I've had this motherboard running for about three months with an E6600 crunching folding@home no problems with the F8 BIOS. I've also had the E8500 in an Asus P5K for the same period of time also crunching folding@home with no problems either. X38-DQ6 was flashed with the F8 BIOS when I initially installed the E8500 this morning, power on and all I get is all the fans start-stop-start-stop ad infinitum with no post or boot. So, flashed with the latest f9f beta BIOS and it still does the same. Power on, all fans spin up for a second then stop, rinse and repeat... Tried it with two different lots of memory, some corsair dominator CM2X1024-8500C5D and some corsair M2X1024-6400C4. CMOS has been cleared, cables etc checked also. The GA-X38-DQ6 PCB has "REV: 1.0" marked on it.

Anybody got any ideas? les...
