desktop won't POST

[zander55]

after changing some settings and attempting to overclock my FSB, my computer no longer POSTs. I built this computer two years ago but never tried to OC it before. what i did was disable floppy disk seek and enable S.M.A.R.T, as well as raising the system bus from 200mhz to 222mhz.

i've tried resetting the cmos already both by turning off the psu and resetting the jumper as well as removing the battery, but no luck.

my motherboard has a l.e.d post port and is giving me a 7f code, however i can't download the manual off of epox's web site and they don't have that information in their general support.

my specs:
AMD opteron 165 processor socket 939 1.8ghz
epox 9npa+ ultra motherboard
2 gigs (2X1gb) ocz ram.
leadtech nvidia 6800gs graphics card.
thermaltake tr2 430w psu.
windows xp sp2.
seagate 60 gb hdd.
22w2 westinghouse monitor.

if you need anything else let me know. thanks in advanced.

Appendix C of the manual lists the LED error codes. For 7F, it states:

1. Switch back to text mode if full screen logo is supported
-If errors occur, report errors & wait for keys
-If no errors occur or F1 key is pressed to continue:
Clear EPA or customization logo.

Not sure if thats going to help you. I also found some people saying a bad floppy or reversed floppy cable caused this error.

thanks, figured it out.

the problem was my monitor wasn't auto detecting the input after that.

just pressed the button and it boots fine.
