My mom is 85 and uses her computer for mostly email and playing the installed games that come with the operating system. She got it from her local senior citizens center so it came without any disks. She asked me to help her with a problem she says she's been having for a while. She says that means over a month. I thought I'd try a system restore but discovered it had been turned off so that wasn't an option.
Her computer is a Dell Optiplex GX260 with Win XP Pro SP3 and a Pentium 4 2.00GHz with 512 MB RAM on a single stick. What is happening is she gets random restarts of the OS. I brought her computer to my house and the same thing happens. It usually takes from 5 to 15 minutes for it to happen. It does not happen when I boot to safe mode. I installed Avira Free Antivirus on it some time ago and it's virus defs are up to date.
Since I've had it I have done a full virus scan with no issues being reported. I've also run MBAM without any issues reported so I thought maybe that is not the issue.
I stopped the auto restart feature so I could get a look at the blue screen and it gives the stop code:
0X00000050 Page Fault in Nonpaged area. I read the description of the 0X50 code and based on that I downloaded Memtest v3.3 and ran it from a diskette. I let it run though 8 tests and it reported no errors.
So I think I'm beyond my abilites to fix this thing without help. Thanks in advance for any assistance.
