Asus p4p800-vm

some suggestions:

* remove all ram and use 1 stick of ram in slot 1.

* visually inspect the capacitors on your board to see if they are bloated or top cracked open.

* remove data & power from DVD-ROMs, non-essential hdd and etc devices.

* if u oc, return to default spec.

* check key-mouse ps2 correctly conected. some boards with swap'd ps2 will not boot. bad bios programming.

*** watch out for static. it'll kill devices silently.

yr system full spec. would be very helpful here :)
