I'm dealing with two computers, both the same model (can't remember the model. Will finally have access to them tomorrow.) Can't quite say if these were acquired second hand, but they were once used alot back when they were still functional. Both computers where having some problems, which unfortunately, nobody could tell me what those were. These computers where stored away for quite some time, and nobody remembered what problems they had back when they decided to store them.
Both computers were already missing several components, since they were taking out pieces from these computers to fix others. I will refer to these as "PC1" and "PC2" from now on.
So when I got these two computers, PC1 had everything but a video card and no RAM modules. PC2 had a video card and RAM, but no power supply, no CD-Rom and no HDD. I decided it was easier to build upon PC1, so I took what PC2 had and installed it on PC1. Of course, both computers where breaming with dust and trash some of the students would shove into it, so I cleaned PC1 before installing anything. Didn't clean PC2 because, well... I wasn't about to revive that one, heh.
Once everything was connected, up and running, I attempted to format PC1's HDD and reinstall Windows XP. However, upon loading the necessary drivers into RAM before the installation process began, the screen would show the famed white lines when the partitioning screen appeared. This only happened until I switched PC1's Power Supply with a different known working Power Supply. PC2 didn't get these lines at all, since I was using the same spare Power Supply I initially hooked up to PC1. But even so, both computers would go into some sort of "stand by" mode after reaching the partition screen. The computer wasn't actually turned off, but only seemed to turn off the HDD and have the computer fans running at slower speeds than normal.
One would normally think that maybe the HDDs where faulty, but I tried 3-5 different HDDs, and none of these seemed to make a difference.
So... yeah. I have two computers, and I'm trying to build a single working one using parts from both.
