I ordered a new PSu and Graphics card, which i just recieved today. I put in the PSU, and everything is fine. I remove my old GPU and put in the new one (an ATI Radeon HD 4850), and plug in the 6-pin PCI-E connector. I push the power button, and the blu LED on the PSU flashed on, then nothing. The computer refuses to start.
This is the PSU i bought: Newegg.com - Rosewill RP600V2-S-SL 600W SLI Ready-ATX12V V2.01 Power Supply 115/230 V CSA,UL,TUV,FCC - Power Supplies
I think it's the graphics card, becuase the PSU works, but i've heard of people having problems with this unit under powering their system.
