Hi, my computer was getting really slow, so I reset windows. After that, the computer would randomly shut off, and wouldnt turn on unless I removed the ram and reinserted it. This stopped after awhile, though, until I upgraded the ram. The ram I had before were two 1gb 400ghz sticks, so I upgraded to 4 2gb 800ghz sticks. The pc was alot faster after that, but when ever I go to play big games on it for awhile, or leave the pc on for a bit, itll shut off and will only attempt to turn on when I unplug a ram card and reinsert it. But the most itll do now when doing that is it will simply not turn on, itll power on for a second then turn off, or itll power on for a minute or so then shut off. More often though, itll just power on for a second then turn off... Does anyone know a fix for this?
