Having trawled through previous post I believe I may have the bios corruption problem!
When I turn on my PSU the red LED on the motherboard lights. When I turn on the PC the green LED lights, CPU fan, chipset fan case fans etc on come on. The HD LED lights for a while then goes out. During this process I get nothing to the monitor. There are not unusual beeps and the PC seems to just stay like that. Oh and its not just a display problem as when the HD ligh finally goes out the number lock key has not effect so its not just sitting there fine with no display.
I have tried the following:
holding down the Insert key while booting - (multiple times)
clearing the CMOS - (multiple times)
I have had boot problems a couple of times before and clearing the CMOS worked fine so I don't think I am doing anything wrong although I have not tried removing the ATX power connectors or removing the battery yet.
What would be the easiest way of proving/identifying the problem. I have access to a second completely identical system so I can replace components in order (swap bios chips?).
I also have access to a Tbird 850 100fsb - I have heard this can resolve boot problems in some cases!
I thought I would try the ram first (easiest), the graphics card then the Tbird 850 - a little nervous of the CMOS chip really don't want to break another mb.
Any other suggestions/pointers??? See below for my system details and how I got into this mess!

My system.
Chieftec case (360watt chieftec psu)
NF7-S v1.2 bios 1.5
Single stick 512mb twinmos PC2700 cas 2 (Dimm 3)
Sapphire 9100 128mb
WD 80GB (SE)
XP1700+ (Tbred 'B') Jxxxx
Coolermaster HAC-V81
Sony DVD
Aopen CD/RW
What i was doing.
Nothing too dangerous - I was attempting to find the stable limit of the memory and CPU.
12x166 worked fine (vcore up 0.025)
Checking the ram/fsb ram - expert (6 2 2 2)
stable at 10 x 179
unstable at 10 x 180
dropped the multiplier (only trying to check fsb)
still unstable at 8 x 180
loosened timings (8 4 4 3)
stable all the way to 8 x 188
8 x 190 - would not boot re-set cmos - fine
7 x 189 - would not boot re-set cmos - fine
loosened timings (15 7 7 3)
7 x 189 - would not boot re-set cmos NOT fine - re-set cmos etc etc !!!!
