I have put many pc's together. They have all worked fine. Now I seem to have fried my second amd 64x2 in an asus a32n8sli. I have had all brass posts under at least 5 mobos in this one case, never used any fiber washers. Never read any where in the installation books to do so. No washers were provided in the screw kit. I rma'd the board and the processor, and they worked fine for maybe two months. Then while installing RC2 I got the boot error that there was a problem accessing the storage device. I gradually stripped the system, substituted all hardware. The whole 9yds. It powers up, fans run, memory activity led blinks once, then absolutely nothing but the whirring of little blades. There is no heat generated by the cpu. Bottom line is to rma the processor again, spending 80 bucks to ship it to Holland. But I would like to know if I have been committing some techno sin by not using washers somewhere over or under the board. Dale.
