Hello, I picked up a refurbished Dell Optiplex GX270 with an Intel P4 2.8Ghz processor and 1 Gig ram (4 256MB sticks). I added a Geforce FX5200 AGP video card. There is a fresh copy of windows XP installed just 3 days ago. The only software that has been installed is itunes and firefox. The computer is experiencing BSOD's pretty much regularly. They always have different messages, but seem to all point to the RAM possibly being faulty. I have run memtest86 on the system by downloading and burning the ISO and booting it from the CD drive. I am having weird results. First I tested ALL 4 sticks together I immediately got an error at about 34% coverage, then another error around 75%. Both occurred less than 10 minutes in. So I shut it off and pulled out one set of RAM, leaving one in. Let it run for about an hour and no error. Switched the sets around so as to test the second set and try and narrow down which stick is bad, and test for another hour and no error. Then I tested them all together again and even quicker than before I got errors. First error came at 14% and by 100% I had 4 errors. Then I began testing each one individually and again allowed each to run for over an hour and none give an error. Why is the RAM failing when tested together, but not when tested individually? Anyone with any suggestions please help.
I will detail the important parts of each blue screen below, The order they appeared in I cannot remember. I will give the error string and the first 0x code. If any more info is needed, please feel free to ask and I will do the best to give it if I can.
I think the first BSOD error was a PAGE_FAULT_IN_NON_PAGED_AREA and I did not write down the 0x code.
I have also received the following ones after that:
We pretty much receive one of these BSOD's every 2 hours of using the computer. I am likely going to be purchasing new RAM for it anyway because I'd like to upgrade to 2 gigs and will need to buy 2 1 gig sticks. I just want to make sure I'm not wasting money if something else on the computer is faulty. Thanks for any help.
