I recently upgraded from an Intel E6400 to a quad core Q9550 using a BIOS updated Asus P5W DH Deluxe, this with Windows 7 64-bit and have had nothing but failure trying to use FSX SP2. I have a GeForce 8800 GTS with up to date drivers. The E6400 had no problem with Win 7 and FSX,had lots of sucessful flying, not with the Q9550 however, nothing but computer freezes within 5-20 min. of any attempted flight. I have read online about problems using a quad core with the P5W. Comments? I have update every driver I can, including the chip set, Intel i975's.

I'd suggest formatting the HDD after a CPU swap - that's my personal opinion though.

Thanks for the suggestions and links guys! Obviously, the Q9550 is to much for the older mobo. I'll move on and get a better board or backpedal from the Q9550 for now in favor if an i7 setup later.

Final follow-up. Yup, I dumped the old P5W DH Asus with the i975X Intel chip set, plopped my new Intel Q9550 into a new Gigabyte EP43-UD3L and have never looked back. FSX is very happy and so am I!
