So I am putting my old computer back in the old case now that I have my new one. The old one being a KT266a mobo, 1.2ghz Tbird, 2x256mb PC133. I plugged everything in and got my XP cd out, but it doesn't turn on. It was like the power button isn't doing anything. So I figured it was likely that I plugged in the power switch wrong on the mobo, but gd I have checked and rechecked those connections about 10 times now. The only other thing I could think of is the ATX plug not being all the way in on the mobo, but I have checked and rechecked that one a lot. I even pulled the whole system apart and remounted the mobo on the screws all over but still it just doesnt turn on. Nothing happens when I hit the power button. And these parts are coming from a system that I have used for years so I don't see how they would be defective. Granted I did remove the mobo, cpu, ram from the case and it sat for a month or two till I got a new case but I was never rough with it obviously. The only thing "new" is the 5gb hard drive which could be hosed for all I know but the computer would still get power and start POST.
Any ideas??
