Hello,

I hope you all can help me. I replaced a CPU stock cooler (replaced Intel heat sink/cooler with corsair h80) and now my computer won't post, the keyboard will flash on then off and I get the 'no signal input check video cable' message on my monitor. Everything else works fine! I put this thing together from scratch at least 7 times over the last 2 days and I am los.t I even put the old Intel stock cooler back in and got nothing.

Specs:

P6X58D Premium motherboard
Hanns-G monitor
i7920 CPU
ATI Radeon Sapphire 5850
G-Skill DDR3-1600
Corsair TX750W power supply
Corsair h80 hydro cpu cooler

I did read the sticky at the top of the forums about this issue. Still nothing has changed and I am stuck. I don't want to take this to Geek Squad if it's something simple.

What does that mean? Do you hear a single short beep (if you have a case speaker installed) as your system completes the POST?

No beep, everything is not working fine.

Do you get a "TaaDaa" sound when Windows finishes booting (assuming you had it before)?

If no "TaaDaa", everything is not working fine. If "TaaDaa", test the video card in another system.

jsc,

I stated in my post that that the computer didn't post. I was being sarcastic after listing a litany of problems. I have to remember that online that sarcasm doesn't always translate well. Sorry.

I don't know if Windows (yes I have Windows 7) finishes booting. I stated previously that I get a 'no signal input check video cable message'. So I can't see anything.

Regarding that link, I saw that thread and some other threads about that. I stated previously that I've taken this thing apart and put it together numerous times, that's why I need help. Obviously I have missed something.

The fan on the video card spins, yet it doesn't show output on the monitor.

Thanks!

Bump

I tried a new motherboard; same problem. Would it be a good idea to try a new PSU?
