Hi, I am running a P5N-D motherboard ( bios 1401) with an intel core 2 quad Q9300, Rad HD3800 series and I have some problems since last week. It started with an error 0cx00000e9 someting About USB being disconnected. Since I couldn't figure out the problem I reinstalled windows 7 64bit. The install was really slow. I tested the hd, fine, the ram, fine, processsor, fine, deactivated USB no change, new video card, still no change. Now tne computer is really really slow to boot up. Once it's running, it's fine but turning it on can take over 5min. I am running out of ideas. Any suggestions?
