I have an older computer that won't boot up. It gets as far as 'Detecting HDD Primary Master' [Press F4 to Skip]. There is no response from the F4 Key. I've checked the CMOS and BIOS and they look fine. I haven't installed any new devices except to swap out the Hard Drive to see if that made a difference, it didn't. From what I've read I have come to the conclusion that the BIOS chip is corrupted. I've tried several different Boot Disks to no avail. The MB is a Freetech, I tried contacting them for support but my email was 'undeliverable'. Is there any way to determine whether or not the BIOS is working and if not how to repair it. The chip set is an Intel Triton TX. And the Bios is an Award No. 2A591F29C-00. If you have any guesses as to what might be the problem I would like to hear from you.
