broke my motherboard

[Salazaar]

I've got a Lanparty NFII Ultra B with an Athlon 3200+ and 1GB of pc4000 memory.

I recently pushed the FSB from 215 to 225 MHz with the CPU multiplier low enough to keep the CPU running at normal speed (2.2 GHz, it never did overclock well) and the AGP speed locked at 66MHz.

After I rebooted with the new FSB speed the mb fails it's post, the LED on the mb seem to indicate that it's failing to initialise the FSB frequency which would make sense. No monitor activity either.

I've tried reseting the CMOS using the jumper and also by holding the insert key which the DFI website reccomends.

Anyone else got any good ideas or is it time for a new motherboard?

Do a proper CMOS clear: battery out, leave it for 5 minutes with the jumper in the clear position, then hit the power switch a few times. Put everything back and try it then.

If that doesn't work you may have corrupted your bios somehow; in which case you could get a new one or get someone to reflash your old one.

Rich :¬)

I pulled the power cable, switched the jumper to clear and removed the battery. I left it all night but still no joy when I plugged everything back in.

How would I go about replacing/reflashing the bios?

Thanks and happy new year.

I once had a board which played dead completely even after loads of cmos clears. What eventually brought it back to life was hitting the power switch a few times (with the board plugged in obviously) with the jumper in the clear position. If you haven't tried that, then do.

If that doesn't work, the easiest but riskiest way to get a working bios is to find someone with the same motherboard and do a hotswap flash. In theory, if you can find a board with the same bios ship socket, you can use uniflash to flash if even if it's a different board.

I've done a hotflash a couple of times; the only problem I had was when I shoved a bios chip in backwards (a pretty stupid error) which killed it- it got very hot very quickly.

Otherwise there are some companies who will sell you a replacement bios chip with a new bios on it for a tenner or so. I can't recommend any specifically though I'm afraid, but I'm sure there will be people on the boards who will be able to help.

Send the BIOS chip off to someone who has the same board and get them to flash it.

What bios are you running and had you read the "Unofficial" Infinity/ LAN-Party "B" FAQ over at Amdmb forums? That has solutions to booting probs & it sorted mine out when i had the all 4 led's lit but no boot. Not same prob as yours granted but it may help.

Thanks for all the help guys.

DFI have agreed to send me a new BIOS chip, hopefully that'll sort it all out.

I used to have this problem with one of my ASUS boards (cant remember which one either nF2 or KT133A) but it would be sorted buy loads of pressing/holding combinations of the power and reset buttons in as well as sometimes hard powering down (switching hte PSU off while its powered up. Also dont forget the INSERT key trick - that works in 50% of dodgy FSB selections

Glad to say my current board isnt as picky and does re-set.
