Question about PC Desktops

1 Answer

I reformatted my hard drive a month ago, due to my nephews viewing **** videos, which caused a message to constantly pop up that my computer was infected and I needed to download/and pay for a product. My computer hasn't worked correctly since. When shutting down, I do not have the option of choosing 'standby' mode. If I work on it for a long length of time, I am locked out, and I can't shut it down in the normal manner, and my programs cease to work. I am forced to hold the button down to shut down. Do you have any help for me? Or is this a Windows problem?

Easiest way is to do fresh install your windows.

To do this, please boot from your Windows CD installation, then reinstall. While reinstall, do format the installation partition.

Have you tried running check disk? Or if this is a new installation, try reformat the hard drive to eliminate corrupt data.

If you are familiar with BIOS settings, try changing the SATA mode from AHCI to Compatible.

Things You Must Know To Avoid PC Crash Part 2


4 Hard disk drives
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to
* Start-Programs-Accessories-System Tools-Disk Defragmenter
This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.
The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).
Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to
* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.
Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.
Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to
* Start-Programs-Accessories-System Tools-ScanDisk
Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.
5 Fatal OE exceptions and VXD errors
Fatal OE exception errors and VXD errors are often caused by video card problems.
These can often be resolved easily by reducing the resolution of the video display. Go to
* Start-Settings-Control Panel-Display-Settings
Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.
If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to
* Start-Settings-Control Panel-System-Device Manager
Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.
If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.
Another useful way to resolve video problems is to go to
* Start-Settings-Control Panel-System-Performance-Graphics
Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).
Look up your video card's manufacturer on the internet and search for the most recent drivers for it.
6 Viruses
Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to
* Start-Settings-Control Panel-Add/Remove Programs
Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.
A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.
An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).

Reasons why Hard Drives fail.


A hard drive's file system may become corrupted or damaged due to a virus or software malfunction, but this is not a true drive failure because in most cases you can reformat the drive and reinstall the operating system and everything is back to normal. Hard drives fail due to a malfunction in their mechanical or electrical components.

The following picture illustrates the major components inside a hard drive:

f7bfbc4.jpeg


The following is a list of the most common mechanical failures that can happen.

1. The spindle motor can malfunction. The spindle motor works much the same way that cd-rom or dvd player spindle motor works and is located in the middle of the hard drive platters. In a hard drives case, it's job is to spin the platters.

2. The read/write heads malfunction or the actuator arm malfunctions and prevents the read/write heads from reading the data stored on the hard discs (the platters). The picture below shows a closer view of the platters, actuator arm, and read/write head.

3. The hard discs themselves can become damaged by rough handling (dropped) or can in some cases become scratched by the read/write heads if they touch the disc.

4. On the back side of the hard drive case you will see where the cable and power supply plugs in and you will also see where the jumpers are. These contain small pins and can easily be bent or broken.

79246c5.jpeg

5. Another problem that can occur is the cables and ribbons themselves become loose and do not make a proper connection or the cable themselves can become damaged. The power cable can also become damaged or malfunction.

Picture of a SATA cable.

Hard drives can also fail due to malfunctioning or damaged electronics on their circuit board.

28b1869.jpeg

The most common electrical components to malfunction are Transistors, Capacitors, and Resistors. Power surges are the common cause of these small components to fail, so remember to make sure you are using a good surge protector or a UPS system for your entire computer system. A good policy is to always unplug your computer system from outlets when a storm is capable of producing lightening. It is also important to remember that if any of these failures happen, it will be cheaper to replace the drive for a new one. You can return a hard drive to the manufacturer to be fixed if it is still under warranty. Read your documentation and warranty information carefully if you purchase a new hard drive to upgrade/replace your old one.

The following picture is an illustration of where the hard drive is located inside the computer case. In this case, it is a SATA hard drive.

My computer lost ( ntlpd is missing) plus said press ctrl alt del it's not coming up.


Sounds like you've got some corrupted files. If you have your Windows disc, try a reinstall/repair or try to drop back to a previous restore point.

If those don't work, you might try to reformat/re-install your software. (backup your data if you can beforehand as reformatting will wipe all data from the drive).

This can even be a hardware problem, like the HD controller bad, which caused the file problem in the first place. Or a virus can cause such issues, which would make reformatting/reinstalling a good idea as well.

Make sure you have a defragment task running every month, if not every week. You can schedule to run at night or during the day, whenever you're not at the computer. If you turn it off when you're not using it, just leave it on that one day (or night) that the defragment needs to run... or start it manually before you go to sleep and unless it's a large drive, it should be done when you get up.

Good Luck!

I just want to restore to factory defaults


The best way to reset your Laptop to Factory Default is to reformat it. Depending on which version of Windows you have this will create a directory in your Hard Drive called Windows.old, or depending on whether or not you deleted the partition, it will erase everything. You'll want to back up your hard drive if you have anything worth saving.
Beyond that, pop in your recovery disk, or if you don't have it, put in your Windows disk, then restart your computer. When your computer is booting up, head into the BIOS and set your computer to boot from your DVD Drive. If you aren't sure how to do this then reformatting is probably not a good idea. Once you've booted from the disk, just follow the instructions to reformat.

Alienware Aurora CDROM and Hard Drive Issues


Some SATA/RAID controllers require you to install the drivers during the setup of Windows. Otherwise, you'll get the message you received. Download the drivers and put them onto a floppy disk for use during setup and at the start of the Windows setup, you will be prompted to press F6 to install these drivers. If you don't have a floppy drive, don't worry. You can slipstream the drivers into a setup disc that you can create. To do so, follow the methods here:

If you have a spare computer or can get to someone that can help, remove your hard drive and install it as a "data" drive in another system. The other system can then remove the partial installation and start over. A last resort would be to reformat the drive. It might be possible to reformat it with a DOS (or Windows 95/98) boot floppy. Be very careful as DOS does not always work well with newer hard drives.

Trubleshoot Motherboard


More than 70% of all computer problems are related to cabling and connections. Ensure all cables are connected and connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Ensure microprocessor, memory modules, and adapters such as video card are inserted correctly and didn't "pop-up" due to vibration.
System has no power at all. Power light does not illuminate, fan inside the power supply does not turn on, and indicator light on keyboard does not turn on. PROBABLE CAUSE DIAGNOSIS SOLUTION
Power cable is unplugged. Visually inspect power cable. Make sure power cable is securely plugged in.
Defective power cable. Visual inspection, try another cable. Replace cable.
Power supply failure. Power cable and wall socket are OK, but system is still dead. Contact technical support
Faulty wall outlet;circuit breaker or fuse blown. Plug device into socket know to work and test. Use different socket, repair outlet, reset circuit breaker or replace fuse.

Expansion card is partially dislodged from expansion slot on the motherboard. Turn off computer. Take cover off system unit.
Check all expansion cards to ensure they are securely seated in slots. Using even pressure on both ends of the expansion card, press down firmly on expansion card.
Defective floppy disk drive or tape drive. Turn system off.
Disconnect the cables from one of the floppy drives. Turn on the system, check to see if the keyboard operates normally. Repeat until you have located defective unit. Contact Technical Support.
Defective expansion card. Turn computer off.
Remove an expansion card. Make sure expansion card is secure in expansion socket.



System does not boot from hard disk drive, can be booted from floppy disk drive. PROBABLE CAUSE DIAGNOSIS SOLUTION
Connector between hard drive and system board unplugged. When attempting to run the FDISK utility described in the HARD DISK section of the manual you get a message, INVALID DRIVE SPECIFICATION. Check cable running form disk to disk controller on the board. Make sure both ends are securely plugged in; check the drive type in the Standard CMOS Setup (in your motherboard manual).
Damaged Hard Disk or Disk Controller. Format hard disk; if unable to do so, the hard disk may be defective. Contact Technical Support.
Hard Disk directory or FAT is scrambled. Run the FDISK program, format the hard drive(See HARD DRIVE section of manual). Copy your backup data back onto hard drive. Backing up the hard drive is extremely important. All Hard Disks are capable of breaking down at any time.



System only boots from Floppy Disk. Hard Disk can be read and applications can be used, but booting from Hard Disk is impossible. PROBABLE CAUSE DIAGNOSIS SOLUTION

Error message reading "SECTOR NOT FOUND" or other error messages indication certain data is not allowed to be retrieved. PROBABLE CAUSE DIAGNOSIS SOLUTION
A number of causes could be behind this. Use a file by file backup instead of an image backup to backup the Hard Disk. Back up any salvageable data. Then do a low level format, partition, and high level format of the hard drive( see Hard Disk section of your manual for instructions). Re-install all saved data when completed.



Disk formatted on IBM PS/2 will not operate with this system. PROBABLE CAUSE DIAGNOSIS SOLUTION
The IBM PS/2 uses a different format than other computers. IBM PS/2 disk format will not work in an AT type computer. Format disk in the AT type computer insert disk into the IBM PS/2 and copy the files you wish.



After install an expansion card (network card, tape drive card, etc.) the system no longer works properly. PROBABLE CAUSE DIAGNOSIS SOLUTION
No power to monitor. All or part of the system may be inoperable. The new card may work but a mouse or COM port may not work. Change the interrupt or RAM address on the new expansion card. See the documentation that came with the new card in order to change pin settings. many expansion devices come with proprietary software that will assist you in doing this.

I think my compaq presario desktop has crashed


the computer is not recognizing the contents of your hard drive. you'll need a floppy with command.com, iosys.com and sysinfo.com on it. when inserted into the drive cmos looks here first. if you can access the cmos, check the search parameters to see what the computer boot up sequence is. you may want to change it to recognize the cdrom first, then the hard drive, then the A drive. I had a compaq armada that gave me the same message but I was able to reformat the drive off DOS 6.2 and changed the boot up sequence.
