I installed 7 on this particular pc, which is kind of old (pentium 4 3.4ghz, intel 925xcv) and it worked for maybe a few days, then it died. Ended up I had to replace the mobo, which worked and started right up. Just replaced the C: drive (another pc had a bad hard drive so I stole the one out of the older pc) and when I tried to install 7 on it, it would blue screen, and a bunch of other stuff, so I formatted and tried to put XP on it, that didn't work. Now the bios doesn't even load, I get no intel screen, no nothing, doesn't even seem like a display signal is reaching my monitor
