ive been having some problems with my new computer that i built in late June. About a week after building i got a bunch of bsods for about a 3 weeks, until one morning my computer would not post or show any activity of being powered on. so i RMA'd the motherboard, and i re-installed the new board from ASUS and when i went to try and power on the computer its the same as the old mobo. nothing happens, no fans, no drives spin up nothing.
The only thing left that can cause this problem is the power supply, right?
Try changing your PSU, as long as the accessories are plugged into the right slots on the mobo. If your on your second Mobo and nothing seems to be working it's a good chance its the PSU. Better to be safe then sorry as a faulty PSU can cause some serious damage.
