Desktop I built crapped out after about a year. When I go to turn it on, it sounds like everything starts up but cant get the screen to display anything (shows a no signal message at first then goes black).

I figured it was a graphics issue, so I bought a new card, but that didn't do anything. Then, after trying the new graphics card, I reinserted the old graphics card, but used the PCIe x4 slot instead of the PCIe x16 slot that it was in before. For some reason, this resulted in a successful startup. However, after shutting down last night and then starting it up this morning, it's back to the same problem I had before.

Specs:
CPU - AMD Phenom II X4 955 Black 3.2GHz Quad-Core Processor
Motherboard - Gigabyte GA-970A-UD3 ATX AM3+ Motherboard
Hard Drive - Intel 320 Series 120GB 2.5" Solid State Disk
Video Card - Sapphire Radeon HD 6770 1GB Video Card
Case - Antec Three Hundred ATX Mid Tower Case
Power Supply - Antec 620W ATX12V / EPS12V Power Supply

Thank you!
