|I think I just inherited a lemon,|
I verified that there were no hardware problems, the paste is being applied properly, cannot find any error logs in windows or the bios, no blown capacitors. Reinstalled vista, all the drivers, new mouse, new keyboard, new monitor, new cords, just in case. I also put in a new hard drive. I have tried adjusting the screw tightness on the heat sink, it is spring loaded. I have tried thermal grease. It is still doing the same crap where the power supply fan is running, the other fans come on for a second and then turn back off, the computer will not boot when the fans turn back off. Sometimes the fans stay on and the computer boots, but then then the computer shuts off within 10 seconds to 4 hours. Today it was 40 degrees outside, left the computer off all day with the room ice cold, still having the same problems. The temps are running cool when it does boot. temp does not appear to be a problem. Keeping the dang thing turned on is getting to be rather frustrating. Would a faulty power switch cause it to turn off like this? That is the only thing I haven't tested because I do not have an extra one at this time to test out. Something else I found odd was when I loosened the screws it still turned on, but when I took them out completely it would not turn on at all. So I put the screws back in again and it turned on. Could the screws be somehow causing a short?
