Ok friends. I read much stuff in this forum but now... i`m confused... i have: AMD X2 4400+ , DFI Lanparty NF4 Ultra D, and 2x512 MB Corsair XMS C2 (on the sticker on the ram it says XMS 3202 v1.1), Cooltek MST 500 "Real Power" 500 PSU, Gigabyte Geforce 7800GT And YES i have the "coldboot" bug (i think so) If i click reboot from within windows the pc shuts down but it did not reboot. I need to hit the reset button then it boot normal. Same if u turn on the PC. i really dunno wich BIOS to flash, i tried 623-3 etc... but i read something about tccd, utt and that stuff. Dunno what tccd is or utt can anybody help?
