OK, I have an old deskpro 4000 6300mmx which I was going to use for windows 2000 pro. Anyway, it had a copy of ezbios on there which had very limited options and wouldn't let me get to "proper" CMOS setup. Someone suggested that I use a utility to write 0's to the hdd to erase everything and start afresh. Unfortunately I still can't access setup and I've booted up from a Windows 2000 install disk and installed a copy of W2k but still can't boot to it. All that happens now is that it gets past POST, the screen flickers and then nothing, just a blank screen and no response from the keyboard.
I've tried everything I can think of like using fdisk to fix the MBR, I've even set the jumpers to clear CMOS in the hope that maybe that would somehow let me get into setup to reconfigure the date and time etc but I just get an on screen error during post saying that the date and time isn't set and I just get the option to press F1 to boot.
Apparently the correct method of accessing setup for this PC is F10 but that has the same effect as pressing F1 - PC tries to continue booting.
