Hello potential heroes, i have a problem and unlike last time, i don't want to pay $110 to have it resolved. My computer seems to have caught a similar virus to the one it had late last year, which made it shut down at random times, sometimes 3-4 times in an hour, and it's just becomes increasingly irritating and expensive to deal with. I have Norton Anti-Virus, which seems to be helpless against this!

Is there a way i could remove this myself? i'm no computer whiz, so if you want to help, i'll need it to be simple, step by step kind of stuff lol. Does anyone know of a virus that does this? is it possible that it's a spyware issue? Also, what's the best virus protection software on the market today? I think it's time i ditched this Norton deal!

Thanks in advance for your time.

Try running your AV in safe mode. See if it finds anything when it does a complete scan--- then, as a double-check against Norton,you can use one of the many on-line virus scans as well. If neither options points to a virus. If neither of these steps work, then consider the possibility that your problem could also be caused by other, perhaps hardware related, problems.
Whereof one cannot speak, thereof one should be silent.

The symptoms you describe could be malware related or they could be due to hardware or overheating problems caused by a failed processor fan, bad memory (RAM), failing power supply, underpowered power supply, CPU overheating, motherboard, video card, drivers, dirty hardware, etc. If the computer is overheating, it usually begins to restart on a more regular basis.

Check for malware by performing a full system scan with your anti-virus in "SAFE MODE". Also download and scan with MS Malicious Software Removal Tool and AVG vcleaner. Some rootkits can also trigger BSODs, shutdowns and error messages so download and scan with AVG Anti-Rootkit.

If your not finding any malware then its sounds like the latter problem. When was the last time you cleaned the inside of your computer? Dust restricts the airflow and prevents proper cooling. This in turn can cause overheating and faulty processor fans which can result in unexpected shutdowns, random restarts, booting problems, etc.
  • Open your machine, check all the connections and make sure the fans are all operational.
  • Check the heat sink on the processor to ensure it is not blocked with dust or debris.
  • Remove the CPU's cooling unit and clean the fins on the heat sink that sits under the CPU with a can of compressed air.
  • Inspect the thermal compound between the CPU and heatsink as it can break down over time so.
  • Remove the cards and RAM modules, clean the contacts and reseat them.
  • Feel the CPU heatsink when it powers down. It should be warm to very warm but not hot.
  • Monitor the temperature of your CPU, motherboard, hard disks, voltages, and fan speeds.
See "Cleaning the Interior of your PC" and "General Cleaning Tricks & Tips".

Some video cards run so hot that they have their own cooling system. If the fan fails, the video processor will not be far behind and your system may start crashing. If that is the case see "Illustrated How to Replace an AGP Video Card".

In Windows XP, the default setting is for the computer to reboot automatically when a fatal error occurs. You should be able to see the error by looking in the Event Log. An alternative is to turn off the automatic reboot feature so you can actually see the error code/STOP Message when it happens - this is also known as the Blue Screen Of Death (BSOD).

To change the recovery settings and Disable Automatic Rebooting, press WINKEY + Pause/Break keys or right-click on My Computer and select Properties > Advanced tab.
  • Under "Startup and Recovery", click on the "Settings" button and go to "System failure".
  • Make sure "Write an event to the system log" is checked and that "Automatically restart" is UNchecked.
  • Click "OK" and reboot for the changes to take effect.
Doing this won't cure your problem but instead of instead of crashing and restarting you will get a blue diagnostic screen with information displayed that will allow you to better trace your problem. See "Extract troubleshooting info from Windows XP BSOD error messages" and "How to Find BSOD Error Messages".

Also see
"Events and Errors Message Center"
"Windows XP Error Codes".
"Troubleshooting Windows Stop Messages".
"Memory Dumps in XP".
If you don't find the error code you have in any of these links, then try doing a Google search of it.

Download and run Motherboard Monitor 5. If Motherboard Monitor's seems to be reporting high temperatures for your CPU check to see what your max CPU temp is from here.

You can also use NextSensor to check temperature and voltage or SpeedFan to monitor voltages, fan speed, SMART status, and temperatures. SpeedFan can help you investigate the reasons for an unpredictable reboot or for a failing hard disk as well as whether you are likely to experience temperature related issues.

There are suggestions for troubleshooting power supply, video card, CPU, RAM, MB and hard drive here and here.

You can use BurnInTest to stress test the CPU, hard drives, RAM, CD-ROMs, CD burners, DVDs, sound cards, graphics, network connection, printers, video playback. This utility works on all Windows versions to include Vista (32-bit & 64-bit).

Another option is to use Microsoft's Online Crash Analysis. The Windows Memory Diagnostic tests the RAM for errors with a comprehensive set of diagnostic memory tests or you can test your RAM with either of the following tools:

Memtest86+ and follow the instructions to Diagnose with Memtest86+.
Once a bootable disk is made, just leave it in the drive and reboot your computer. However, before rebooting, you need to enter the BIOS setup and make sure that the Boot Order is set so that your first boot device is either the floppy drive or the CD-ROM drive, depending on which type of disk you made. If necessary, change the boot order, save your changes, and exit Setup. When the machine restarts it should boot from your Memtest disk, and the program will start automatically.

Download ISO images for creating a bootable Memtest86 CD-ROM or an installable from Windows/DOS to create a bootable floppy disk or usb flash drive. Read the directions under Technical Info and allow Memtest86 to run through the entire battery of tests for at least 4 full passes (or let it run overnight). Any errors indicate that there is likely a problem with your physical memory (RAM).

Note" If you need to replace your RAM and unsure what type you current have, then use the Crucial System Scanner.

Finally, look for problem entries in Device Manager and check if updates are available for your drivers.
