1. Checked the PSU with a multi meter at idle and under load (Prime 95). All
voltages within specs.
2. Ran Memtest 86+ separately on each RAM module in DIMM 1 for about two hours each.
3. Checked temps with Speedfan. Nothing unusually high. The GPU was a little warm at 63deg. C
but it is a silent card so I guess that's OK.
4. Tested the GPU with a program whose name I can't recall. No errors.
So that's where I stand now, stumped! I can't understand why the XP Pro runs fine with 4GB of RAM (aside from being bloated and in need of clean install) and Windows 7 craps out with the same RAM configuration.
Here is my setup. Epox EP-MF570 SLI, AMD Athlon64 X2 6000+, Asus GeForce 7300GT (Silent). GSkill F2-6400CL6D 8GB (4x2GB). I built this system in 2007 so It's old, like me. Also, I ran Whocrashed and have a report but I don't know how to save the file. Any help would be appreciated.
