And try another video card.
Bob
I just put together a new system with these parts:
AMD Athlon 64 3000+
Asus K8N NForce3
1024 RAM
Maxtor 120 gb hard drive
ATI Radeon 9600XT
I haven't installed windows yet.
When I boot it up, there is no display. The hard drive LED lights up, and the system beeps once, but nothing shows up on the monitor. Can anybody help?
Thanks.
