Ok. It all started when I flashed my bios to version 1B (TCCD Mod). The flash was succesful, but when I rebooted the system it would not post. So I reset the bios using the bios jumper and rebooted, which let to a normal boot and everything was fine. Then a couple of days ago, my USB ports stop working, completely. So I flash back my bios to v1.9 which ends up being even worse! No my PC wont post at all. If I reset the bios (jumper) it boots but hangs after a couple of seconds (after posting). I doesn't stay on long enough for me to flash the bios again. I've not installed any new hardware and I've swapped out the RAM to no avail. Anyone have any suggestions as to what the problem could be? Help!
