I was repairing a computer for a friend. We had to replace the mobo/ power supply. I initially had it booting to windows and it was at the activation screen. I left it for about a week(not on) and since then had to disconnect the power switch/power led and hdd led. Now the computer won't turn on at all(I reconnected the leds and switches). The mobo light comes on but nothing else happens. The computer is a POS celeron on a Intel D845GVSR. I had to remove the switches because the power button got stuck in.
