OK, I'm not exactly computer savvy. But I build my own. A M/B for Socket 754 AMD Athlon 64 Processor ;2 fans on the CPU blowing front to back, a fan on the back blowing back, and a fan on the side blowing in ;2 Vitesta DDR 400 Memory ;2 80 GB Hard Drives ;400W power unit ;and I originally put in a GF 6200 256MB DDR2 TV DVI Video card but the Heat sink broke off when I dropped it one day. Stupid me. Even better. I tried to use it anyway but I kept having my computer crash. Well it really didn't crash. My video card just shut down. I changed my Video card to a Radeon B2 512 HD2600 XT AGP. Now some times, only if I play a high res game its shuts down again. It give me the same " Bouncy no monitor/PC connection" thing on my Monitor. I found if I let my computer sit when it does that, that eventually it will cool off and I will get my monitor back. But recently I go to turn my computer on after being off all night and my PC turns up and my monitor has power but I get that same " Bouncy no Monitor/PC connection" thing. What the heck is going on and how do I fix it?
