tale of stupidity
3 days ago I had to rma an asus mobo back. Figured ok-put in the old mobo temporarily. Wouldn't work. I changed memory, reset the bios, hard drives, pulled all the cards, changed video cards, formattted a drive to fat32, tried to load 98SE, XP, etc. Everytime was an error and never the same one. No luck. Now I have been doing this for a number of years and thought , ok the mobo is fubar.
Last chance, pulled the mobo, started rooting around, and found I had put the heatsink on BACKWARDS!!!.
Oh well. Back to the fix.
