I have just completed my first pc build only to have the inability to post. Everything has power and all of the fans spin including the GPU. However the GPU fan only spins for about 1 sec during power on. It then spins again once I hold down the power button to turn the machine off. All of the other fans including the case and CPU remain running.

Welcome to the forums.
Did you plugged the external power connector into the card?

Yes, Everything is plugged in. All of the fans run contantly with the power on except for the GPU. The GPU fan spins for about a second at power on and about one second again when the machine is powered off.

There are many things that could cause this.. Basically your system is not booting..

I would be willing to bet it is one of your connections. I would disconnect all of your cables etc and replug them..

This just happened to me during my newest build.. If you have messed with the bios I would clear your cmos and use a safe setting once you reconnect all of your cable etc.. I am talking about your hard drives etc...

Good luck

Yes this is a new build and I did install the cpu myself. The thing is I have not been able to post, so basically nothing can be done. I tried clearing the cmos and nothing happened.

Thank you for posting this. I just got finished removing and reinstalling everything. This includes removing the MOBO and even tightening the stanoffs . I also reset the CMOS I made sure all the power cable were connected and everything was where it should be. I also inspected the CPU to see if any pins were bent, they were not. Trying to boot with one stick of ram yielded nothing. A friend at work is going to let me borrow his PSU to see if that is the problem. If not I have no idea what do do.

Well I tried a different power supply and still no luck. I don't have a different GPU to test so I am just going to RMA.
