My girlfriend's Compac computer has for a while been running real crappy and slow. Then it decided to start doing this thing where it won't boot, just sits on the startup screen with the Compac logo and the F1/F8/F11 options displayed. I could get it to boot by doing F11 and then running System Restore to go back a few days. I found that once I got it going, I could restart it and it would fire up just fine over and over, but if I did a full shutdown, it again would not restart. This problem had been ongoing, but the things got worse and it started randomly giving me the Blue Screen of Death. After I saw blue too many times, I finally last week decided to do some physical troubleshooting, and discovered a strange anomaly with the RAM. It has 2 slots, and each slot has a 1GB stick in it. I found that the computer runs beautifully (fast, reliable) with only 1 stick in it. I can put either stick in either slot and it runs great, but as soon as I try to run it with both RAM sticks in, it fails. I haven't done any long-term testing with either stick in either slot, but I did try each combination a few times and got successful fast boot-ups and ran a few programs with no failure.
The machine is a Compac, (made by H-P of course) model SR533WM, running Vista Home w/ SP2, and AMD 64 X2 Dual Core 4200+ 2.20GHz.
Anybody heard of such a problem? I am confused as to WHY this could be happening.
