My friend is completely clueless about her computer. I'm staying at her house and want to fix it for her so I can use it.
What happens is that the computer works - slower than normally - for anywhere from between twenty minutes to three hours or so. Then unpredictability, the computer freezes and the "blue screen of death" pops up; the only choice is to to hit the power button to restart.
The message that pops up is:
Problem detected; windows has been shut down to prevent damage...
DRIVER_IRQL-NOT-LESS-OR-EQUAL (or the alternate notice was: KERNAL_STACK-INPAGE-ERROR)
then it says to disable BIOS memory options like caching or shadowing to deal with the problem, unless the program that has caused the problem could be uninstalled or get the proper updates.
The problem also happens in safe mode.
She first had problems when she downloaded a virus, which sucked her in because she had a package coming through UPS and the email gave some excuse to direct her to a link that downloaded a form she was to use to get her package - which was a virus.
A friend of hers ran a series of programs which improved some of the features, but obviously it did not clean up the problem. One friend of hers installed a paid version of Norton, which expired and did not work on the virus. So I deleted it and installed Microsoft Security Essentials instead. (BTW, when loading, you must manually "turn on" the Microsft Security Essen program - is this normal or part of the virus problem?) However, it will not allow a scan to finish - safe mode or not.
Then I downloaded Malwarebytes and managed to get it to run partway through on a "full scan" mode until it found a malicious down-loader...but this "blue screen of death" would come up before the scan could finish. So I declared the scan "finished" before the "blue screen of death" showed up and was able to eliminate that particular down loader. But I'm suspect that it will be re-created again.
This computer is a Dell XPS DXPO51 Pentium (R) D CPU 2.80 GHz, 2.79 GHz, 512 of RAM, running XP Media Ctr. Edition, Version 2002, Service pack 3.
My other friend has said it also could be an intermittent slowly failing power supply problem, because the 5-volt dc tends to fail on Dells. But I'd really like to know there isn't a hidden resurrecting file virus that re-creates the next down loader.
Any hints about how to clean this up would be really appreciated. I have her plea to please fix this problem while I am visiting for the holidays.
