I have system with ASUS A7V133 MB; Athlon 1.3GHz Thunderbird CPU, 256M SDRAM, 80GB Seagate HD, ASUS 7700 Video Card. Just replaced failing HD and was reloading program, etc. Decided to update ASUS 4 in 1 VIA drivers. At re-boot, the system freezes when it trys to detect set-up. I can get to BIOS but not to safe-launch. I think I corrupted something (the BIOS?) when I tried to update. Any suggestions how to recover from this?
