Ok, so I bought all necessary parts and installed them all aswell, the computer boots up and everything is going smoothly. I start to install Windows and half way through, the power supply shorts out. Small puff of smoke comes out of the case, smelled kinda like burnt rubber or something. Anyway, I checked the motherboard thoroughly and there were no burns of any kind on it. So I tried turning the machine back on. It worked for about 2 minutes and then turned off again. It did this several times.
I assumed the PSU was shot to [bleep] and sent it in for a replacement, same model and everything. I hook up that one and then when I pressed the power button, the lights connected to the power supply flash, the fans connected also start but stop almost immediately, there is a Processor fan that connects through the motherboard that turns on and turns back off. And there is also a little light on the motherboard itself that turns on. So this leads me to believe that the motherboard is not damaged and that the PSU company is just a piece of crap and I should just get another brand.
So I purchase an Antec 500w power supply. High Hopes. Same thing.... Things just flash on and flash off.. I made sure that everything was seated securely in the machine but with no change. Things power on for less than a second before turning off. It's obviously not a PSU issue as I've had multiple of those in it now.
The only thing I could think that could possibly be wrong is that maybe I connected something wrong after removing the first power supply, or the power button is no longer working properly. I have no idea at all.
Any advice would be a big help. If you'd like to know the parts specifically then ask.
