Intel QX9770 Install nightmares

System setup

Asus P5Q3 DELUXE w/ wifi@on
Intel(R) Core(TM)2 Extreme CPU X9770 @ 3.20GHz, 3203 Mhz, 4 Core(s), 4 Logical Processor(s)
4 x 4GB Kingston HyperX DDR3 KHX1600C9D3T1K2/8GX
2 x ATI Radeon HD4850
OCZ-ZX1250W Power Supply

I started out by upgrading the ram from 4gb to the 16gb above to my old Q6700 processor just to get the ball rolling.
Everything was working great.

Installed the new processor.

System began to not turn on all the time, and when it did, it talked about cpu and bus ratio. so i downclocked the ram to 1333Mhz and it booted stable all the time. However, my usb devices started only working 1 at a time. If i have my keyboard plugged in, my external hard drive doesn't show. As soon as I unplug the keyboard, the drive appears.

I have a Logitech G19 keyboard and since the processor upgrade it works for typing but shows up as Device not recognized and the screen doesn't light up.

Went on the forums and tried different voltage settings and whatnot, none came out successful.

I took out the ram and put in my old OCZ 4GB 1066Mhz and it boots good. But the usb devices are still doing the same thing.

I am out of things to try and have determined either my motherboard can't handle the cpu, the cpu is shot, or there is something I am overlooking.

do you have the latest BIOS for your motherboard?

Have you tried resetting the CLR CMOS jumper to set the BIOS to default? (Remove bat first) If problems still persist after that, I would consider the RAM. Many motherboards don't play well with all slots populated with the fastest memory, if it isn't on the QVL.

If you can get your system to boot like it should w/4GB, run CCleaner to clean your system of resource wasting crap and registry errors. Defrag. See if that helps the USB issues.

Have you re-installed the O.S. between processor changes? Windows 7 needs to load certain drivers for different processor generations. If not, I would re-install Win with the processor in place.
