Yeah this might be the reason for not booting. you may find the battry on motherboard, but you could also boot the system by going to setup menu and using first boot from hardisk.

do you get any error messages? open cmd from another computer and ping the pc in question (assuming this pc gets an ip). if "ping" works then try net view \\computer name or ip. you should be able to see the shares or get an access denied usually 5.
Try that and let me know what you got so that i might understand the root of the problem.

Switch ON the PC, boot the PC in 'Safe Mode' by continuously tapping F8 button after you switch On.

Let windows boot in Safe Mode and log in to windows.

Go to 'Start'--->Programs--->Accessories--->System Tools--->System Restore

Here you will have to check "Restore computer to an earlier time' and click Next
Now you will find one Month Calendar window with Dates below, go to the previous month by clicking the '<' sign in the upper left hand corner of the Month Calendar and select any date that you see in Bold.


The detail of that particular date should show "System Checkpoint" and time on the right hand side box. Select that date.


Now, Click on Next and System Restore will start and windows will take a reboot.

After reboot your problem should be resolved.

My hp media center m7160n computer powers up, has a definite fan sound, normally the fan sound diminishes and the computer boots up. For the last several months, the high speed fan sound would not diminish...


How did you clean it?
The last one I worked on had the fins of the Heat sink totally blocked with dust. This will make the fan scream trying to push air thru the heat sink to cool the processor. If it isn't cooled it will shut down in short order.
You must BLOW it out. Use a pressurized air can. Better if you have a compressor with a nozzle.

The other issue may be the interface between the CPU and heat sink is defective. Heat sink moved or become loose.

Of course by this time the processor could be dead also.

Hp desktop won't boot


Firstly how on earth did it get hit with lightening? i have several computers in my house none of which have been hit with lightening during a storm.

secondly it sounds like some of the components are damaged i would try the different components in different machines to rule them out if certain components are damaged you will have to replace them.

I have had this for about 2 years but i havnt used it for about six months when i tried to boot it it just will not boot to the operating system see the second picture for the error message the error...


Ok...

The FIRST thing you need to try, is disconnecting ALL un-necessary devices from the PC... Leaving only 4: Power cable, Monitor cable (unless the screen is built in... I didn't look up your model), Keyboard, and Mouse.

Try booting... We are attempting to determine if any other devices (iPod, Printer Etc.) are interfering with the standard boot process...

If that does not resolve the issue (it likely won't if nothing has been connected to the PC recently), you most likely have corruption on the hard drive's boot sectors... In English: the computer cannot find Windows' boot-up files...

There are SEVERAL ways to fix that hard drive problem without losing your data, but I must insist you let a professional handle that... 1 word: LIABILITY

One last thing... If the PC is SO old, that it has a floppy disk drive... Make certain there are no floppies in it... the PC will try and read that instead of your hard drive.

I'm not sure when it started, because my 17 year old son was the last person to use the computer. I have a 4-year old Dell PC and have been running Norton Go Back just about the whole time. Since late...


my advice is to uninstal Go back as sometimes it stops the boot process, but you may have a faulty drive, so first try starting in safe mode (Pressing F8 on boot up), select safe mode and if it boots into windows you know it's not a hardware problem, but a software one.

dot.gif How to load last known good configuration. Question: How to load last known good configuration.
Additional information: The "Last Known Good Configuration" option was first introduced in Microsoft Windows 2000 and is available in all later versions of Windows including Windows XP. This feature enables a user to load the last working version of Microsoft Windows. This is a great step to try when trying to fix issues with a computer not being able to load into Windows.
Note: Users able to open normal Windows XP mode and who wish to restore their version of Windows to an date before the last known good configuration may also wish to consider doing a system recovery in Windows. Additional information about how to do this can be found on document CH000589.
Answer: To load the last known good configuration in Windows 2000 / XP reboot the computer and as it's booting booting press and hold your "F8 Key" which should bring up the "Windows Advanced Options Menu" as shown below. Use your arrow keys to move to "Last Known Good Configuration" and press your Enter key. Trouble Getting into Windows 2000 or Advanced Options menu - If after several attempts you are unable to get into Windows 2000 or Windows XP safe mode as the computer is booting into Windows turn off your computer. When the computer is turned on the next time Windows should notice that the computer did not successfully boot and give you the safe mode screen.
Note: With some computers if you press and hold a key as the computer is booting you will get a stuck key message as the computer is booting. If this occurs instead of pressing and holding the "F8 key" tap the "F8 key" continuously until you get the startup menu.

Windows Advanced Options Menu
Please select an option: Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode
Start Windows Normally
Reboot
Return to OS Choices Menu
Use the up and down arrow keys to move the highlight to your choice.
As can be seen from the above example, you should be able to highlight and press enter to load the last known good configuration. Once completed the computer should restart and attempt to load into Windows. Will running the Last Known Good Configuration delete anything? No, running the last known good configuration will restore your last good system settings and will not delete anything. The only thing you may have to reinstall programs you have recently installed because the configuration for those programs may have been lost.
