Alright so i got a new motherboard, video card, and CPU. I used a previous owned PSU and hard drive. When i plugged everything in and turned it on, it just made the usual computer noise but nothing showed up on the monitor. THe monitor was actually still in sleep mode. These are the parts i am using:
Windows home edition
Geforcce 8800 GTS alpha dog edition video card
nforce 680iLTsli motherboard
Hyper 540W PSU
2.2 quad core intel processor
please suggest anything!
