After looking in CPUz I decided to see if I could up my memory from DDR333 to DDR400 as all the modules reported they could run at this speed. After changing the values the PC refused to boot.

Now I can't get it to boot at all. I have tried the bios reset jumper several times (has always worked in the past) and tried testing it without various components (sound, graphics, the various memory modules etc.)

The motherboard has a display LCD that shows the boot process, it is getting stuck on 'CF'. Unfortunately I can't download the manual from the abit website to find out what that stands for (I keep getting file not found whenever I click the link on the abit website).

The motherboard is an ABit AN8-v, does anyone know what I need to do to fix it, or (please please please), does anyone have the copy of the manual (an8_series.pdf) and could link it to me or tell me what the motherboard code (CF) indicates?
 
Unplug the PC, then hold down the power button for 10 secs. Then remove the bios battery for 1 min, then finally connect the battery up and reset the bios with the jumper.

Connect up one stick of RAM and try that.

CF stands for "Test CMOS R/W functionality" btw.

Oh, and where are you in Canterbury btw? Up at UKC?

Thanks for link and the adivise :)

Tried the steps you said and it's still sitting at CF. Does that mean the motherboard is screwed? Seems to me that 'Test CMOS R/W functionality' is a pretty fundamental thing to stop working? (it's the first thing on the bios code list).
 
I change the values in the bios. I basically upped the memory to ddr400 setting (rather than ddr333) and lowered the values to 3-3-8 rather than the 2-2-7 they were at, as this was what CPUz told me the chips could take.

Just tried remove battery, remove atx connector, left bios reset jumper on reset for 3 mints, reconnect everything and still dead, LED indicator is stuck at CF :\
 
oh my god, im a total noob. Seems that the first time I moved the jumper to reset the bios I missed the pins when putting it back to 'normal' posistion without noticing. Every subsequent try I was resetting the bios by moving the jumper from 'reset' to 'normal', then back to 'reset' before powering on :|

Thanks for the support though Ucof :D
