My friend helped me built a gaming desktop and it was fine for about a week...then suddenly it turned off, no warning whatsovever, the screen just went blank.
I was able to turn it back on again and it worked fine, until after a few hours it turned off again and won't turn back on again...
I bought a Colors-IT 750W Gold version power supply originally and thought that might have been the problem since it was so cheap...so I bought a new a power supply hoping it would work while I get a refund for the CIT one.
However when I connected the new OCZ 700W Mod-z power supply it still won't turn on?
I tried doing this to turn it back on....
1. Plug the mains adapter to the power supply.
2. Switch the psu on. (I did this both ways...still won't turn on?)
3. Press the on switch on the case.
4. 4 LEDs turn on on the motherboard and the keyboard light turn on but only for a split second.
5. Press the on switch again, no lights at all.
These are the components:
1 x Gigabyte P55-USB3 Socket 1156 Intel P55 USB 3.0 ATX Intel Motherboard
1 x Sony 24x SATA Black DVD RAM-OEM
1 x G-Skill Ripjaws 4GB (2 x 2GB) DDR3 PC3 12800 1600MHz Memory
