Hi great,

All is not lost, when you try to boot up, you may see a "Press F? to enter setup" it goes by quick so you have to watch. Once in DOS environment you can change your boot options, set passwords, if your dual booting you can set the default os , anyway, whatever you change be sure to save and exit. To get yours up, choose safe mode/recovery mode. If os comes up go to start>all programs>accessories>system tools>system restore> choose a date before issue arose>click next/continue, wait for system to recover> reboot and enter DOS environment again and now set boot options to normal save and exit. I hope this helps.

Emachine T 5212, when i turn it on,, a siren sounds,,then computer shuts off


In your computer (as well as other gadgets), the battery powers a chip called the Real Time Clock (RTC)chip. The RTC is essentially a quartz watch that runs all the time, whether or not the computer has power. The battery powers this clock. When the computer boots up, part of the process is to query the RTC to get the correct time and date. A little quartz clock like this might run for five to seven years off of a small battery. Then it is time to replace the battery.

This does not explain why your computer would not boot, however. You would expect the computer to boot fine but have an incorrect time and date. The reason your computer would not boot is because the RTC chip also contains 64 (or more) bytes of random access memory (RAM). The clock uses 10 bytes of this space, leaving 54 bytes for other purposes. The BIOS stores all sorts of information in the CMOS RAM area, like the number of floppy and hard disk drives, the hard disk drive type, etc. If the CMOS RAM loses power, the computer may not know anything about the hard disk configuration of your machine, and therefore it cannot boot.

Many more modern computers are not quite so dependent on the CMOS RAM. They store the settings innon-volatile RAM that works without any power at all. If the battery goes dead, the clock fails but the computer can still boot using the information in the non-volatile RAM area. I would change the battery and make sure unit is unplugged and my other hand is touching the metal frame on the computer to stop static discharge. Blow out the inside of the computer completely.Start computer with case off and make sure all the fans run and don't sound like a siren.Replace anything not running.It may not boot if the BIOS can't see the hard drives. You might have to start computer and watch the screen and when it asks you to hit a key to get into like the bios do it and see if you can reset it. If nothing seems be running right maybe the power supply went out they are real cheep at Tiger Direct.

Is this computer able to dual boot win 7 and xp


Which version of xp are you trying to install 32 or 64 bit ?

Your ability to install a second operating system on your Windows 7 system hinges on one thing: partitions. If your computer has only one partition, you can't dual-boot your system without erasing all information on your computer. Two hard drives, or two partitions, enables you to dual boot. Check this information first, before proceeding.

Click "Start" and type "disk management" into the search bar. Click on "Create and format hard disk partitions" in the list of programs to open "Disk Management." Look at the list of partitions and available drives. The information here will be different on every computer. "C" is your primary hard drive and active operating system partition, and this drive contains your Windows 7 installation. You can't install Windows XP here without formatting the system. Check for secondary drives and partitions in Disk Management. Your system may have a "D" or "E" drive. Some computer manufacturers create a hidden partition with recovery software: don't remove this partition. If you have a secondary partition called "D" with more than 2GB of free space, you can install Windows XP here. b> Installing XP b> Insert the Windows XP Setup disc into your CD or DVD drive and close any windows that appear. Shut down your computer with the disc in the drive. Turn the computer on and look for a message saying "press any key to book from CD." Press any key on your keyboard when this message appears. Most computers are configured to look to the CD or DVD drive first, before booting to the operating system. If your system doesn't recognize the disc, you will have to enter your BIOS and change the boot order. Look to your manual for information on changing the boot order. Press "Enter" on the "Welcome to Setup" screen to load the Windows XP setup program. Read the license agreement and press "F8" to accept. Windows will detect that an operating system is already installed on your primary partition and present a list of other partitions to install XP. Use the arrow keys to select your secondary partition ("D") and press "Enter" to confirm that you want to install XP here. Then choose what to do with the partition: leave the file system intact or format the partition using FAT32 or NTFS. Windows XP supports both file systems, but requires NTFS on partitions larger than 32GB. You don't need to format the drive to install XP. Follow the prompts on screen to enter your personal information, serial number, and date and time. The setup program copies files to your PC and reboots -- don't press a key to boot to the CD. When you have to operating systems installed, a DOS screen appears asking you to choose an OS; press the down arrow key to highlight Windows XP and press enter to complete the setup. You will have to choose this every time to boot into XP, otherwise your computer will boot to Windows 7 by default. Hope this helps.

My hp pavilion a1420n wont boot up. It shows the blue xp startup screen and then goes to a black screen with a blinking white line in the top left corner.


Hi...jimmylang13...

Start your computer in the Safe Mode.
To start in Safe Mode
Turn your computer on
Keep tapping F1,F2 or F8 while the computer is starting up
When the computer starts select Safe Mode..(depends on your computer).
1. Uninstall any softwear you may have put on the computer before the problem started.
2. Do a complete System Restore: Start>All Programs>Accessories>System Tools>System Restore.
This will bring your system back to a time before you installed the softwear or Microsoft installed drivers,etc.
Note: Just be sure to use a date in a darkened box before your trouble start date.
When you have done the above, restart the computer and if your still getting the blue screen of death, the installed drivers,softwear,etc might have
corrupted the Operating System.
If that happened then that means either repair or reinstall the operating system.
You will need to do the following:
1...Repairing the Operating System...
A...You will have to have the Operating Dics that came with the computer.
Note...If you do not have the disks that came with your computer or the ones you should have made when you first got your computer...then you will have to go to the manufacture's webpage and see if they have a recovery disk available for your computer, if they do not a recovery disks available then you can also try ebay to locate the recovery disks.
The original disks will have your product key number that came with the computer, you can also find it on the tower, or under the bottom of your laptop, or maybe the piece of paper that the CD orginally came in may have the number on it.
You can also download a small program and it will tell you your product key number.
Go to the following webpage to download your FREE key finder.
http://www.magicaljellybean.com/keyfinder/
B...You will now insert the disc into the CD/DVD player
C...Restart the computer
D...When the window opens that tells you to press "Any" key, you will press any key you want to press.
E...If you do not receive a message that says "press any key to boot from CD", then then the computer is not ready to boot from a cd.
To correct this problem you will have to go into your computer's Bios and change the computer to boot from a CD.
To get into the Bios, shut the computer off,restart, while the computer is starting up keep tapping F1 as the computer is starting up.
When you are in the Bios, select to boot by CD by moving the cursor with the direction arrows on the keyboard.
Once you have selected to boot by cd the exit and restart the computer...the disc is already in the cd/dvd player.
Your system will then boot from the cd.
F...After a minute or less it should ask you if you want to Quit Repair, or Continue.
You will select Repair this time, but you may have to come back here and select Install if the repair does not work.
It will ok the agreement document if it asks you too.
Tap F8 on your keyboard to pass it when ready.
It will ask you if you want to Install, Repair, Delete Partition, or Quit.
Select Repair
Inside the box there will be one or two partitions.
Choose the largest partition.
After you have chosen the largest partition, you will then press the "r" key to start the repair
After the repair is complete, then you will need to restart your computer.
G...Computer Restart
After the repair is complete, shut the computer down (the computer will shut down a few times during the installation of the operating system
that is normal).
Then restart your computer, when the computer restarts it will have a box to put your product key...put the product key in the box and click.
The computer should start up and run as if it was a new computer.
You do not need to re-register
You can now remove the disc.
-----------------------------------------------------------------------------------------------------------------------------------------------
If this fails to clear your blue screen of death then you have a hardware problem.
It could be faulty ram
If you still get the BS (Blue Screen), then you have two choices.
1.Reinstall the entire Operating System and you may have to update some drivers.
This will require you to go back to the start of the repair info and select Install instead of Repair.
2..Take your machine in to have the hardware tested.
Keep in mind that if you do a complete reinstall of the Operating System you will lose all the information on the computer,such as pictures, programs, videos, everything you installed will be gone.
Please take time to rate me four thumbs up

Get a copy of the right boot CD, set the computer for OS install mode, and boot from the CD itself. It should automatically start the installation from the Cd you put in.

What happens inside the PC between turning the power on and you see the desktop on the screen?


  1. The internal power supply turns on and initializes. The power supply takes some time until it can generate reliable power for the rest of the computer, and having it turn on prematurely could potentially lead to damage. Therefore, the chipset will generate a reset signal to the processor (the same as if you held the reset button down for a while on your case) until it receives the Power Good signal from the power supply.
  2. When the reset button is released, the processor will be ready to start executing. When the processor first starts up, it is suffering from amnesia; there is nothing at all in the memory to execute. Of course processor makers know this will happen, so they pre-program the processor to always look at the same place in the system BIOS ROM for the start of the BIOS boot program. This is normally location FFFF0h, right at the end of the system memory. They put it there so that the size of the ROM can be changed without creating compatibility problems. Since there are only 16 bytes left from there to the end of conventional memory, this location just contains a "jump" instruction telling the processor where to go to find the real BIOS startup program.
  3. The BIOS performs the power-on self test (POST). If there are any fatal errors, the boot process stops. POST beep codes can be found in this area of the Troubleshooting Expert.
  4. The BIOS looks for the video card. In particular, it looks for the video card's built in BIOS program and runs it. This BIOS is normally found at location C000h in memory. The system BIOS executes the video card BIOS, which initializes the video card. Most modern cards will display information on the screen about the video card. (This is why on a modern PC you usually see something on the screen about the video card before you see the messages from the system BIOS itself).
  5. The BIOS then looks for other devices' ROMs to see if any of them have BIOSes. Normally, the IDE/ATA hard disk BIOS will be found at C8000h and executed. If any other device BIOSes are found, they are executed as well.
  6. The BIOS displays its startup screen.
  7. The BIOS does more tests on the system, including the memory count-up test which you see on the screen. The BIOS will generally display a text error message on the screen if it encounters an error at this point; these error messages and their explanations can be found in this part of the Troubleshooting Expert.
  8. The BIOS performs a "system inventory" of sorts, doing more tests to determine what sort of hardware is in the system. Modern BIOSes have many automatic settings and will determine memory timing (for example) based on what kind of memory it finds. Many BIOSes can also dynamically set hard drive parameters and access modes, and will determine these at roughly this time. Some will display a message on the screen for each drive they detect and configure this way. The BIOS will also now search for and label logical devices (COM and LPT ports).
  9. If the BIOS supports the Plug and Play standard, it will detect and configure Plug and Play devices at this time and display a message on the screen for each one it finds. See here for more details on how PnP detects devices and assigns resources.
  10. The BIOS will display a summary screen about your system's configuration. Checking this page of data can be helpful in diagnosing setup problems, although it can be hard to see because sometimes it flashes on the screen very quickly before scrolling off the top.
  11. The BIOS begins the search for a drive to boot from. Most modern BIOSes contain a setting that controls if the system should first try to boot from the floppy disk (A:) or first try the hard disk (C:). Some BIOSes will even let you boot from your CD-ROM drive or other devices, depending on the boot sequence BIOS setting.
  12. Having identified its target boot drive, the BIOS looks for boot information to start the operating system boot process. If it is searching a hard disk, it looks for a master boot record at cylinder 0, head 0, sector 1 (the first sector on the disk); if it is searching a floppy disk, it looks at the same address on the floppy disk for a volume boot sector.
  13. If it finds what it is looking for, the BIOS starts the process of booting the operating system, using the information in the boot sector. At this point, the code in the boot sector takes over from the BIOS. The DOS boot process is described in detail here. If the first device that the system tries (floppy, hard disk, etc.) is not found, the BIOS will then try the next device in the boot sequence, and continue until it finds a bootable device.
  14. If no boot device at all can be found, the system will normally display an error message and then freeze up the system. What the error message is depends entirely on the BIOS, and can be anything from the rather clear "No boot device available" to the very cryptic "NO ROM BASIC - SYSTEM HALTED". This will also happen if you have a bootable hard disk partition but forget to set it active.

When It goes to loading screen it restarts


It is becasue of your computer is not properly shut down and so your harddisk has some bed indexing of memory location.
For that you need winxp disk or recovery disk.
Then boot your computer with that disk .
You have to set first boot device as your cd or dvd rom.;
For that when you power up press F1 or F2 or "del" key to enter in bios .
Then go to boot option then sewt first boot device as your cd or dvd rom.
then save settings then put winxp or recovery disk in rom.
Then follow the procedure .
Then enter in recovery console then type in prompt "chkdsk /r"
then it fix error on harddisk.
Sometimes this command fix eror and then after restart windows load normally but sometimes need to repair windows.
So after check this if still face issue just chose "r" when it finds your previous version of windows then it recovers your windows.

Let me know if you need more assistanse.
Thanks.
