Cleared CMOS, now will not boot

[FlyingPigGod]

I was lowering my memory timings and I went too low. I set the CMOS clear jumper to clear and left it for 10 seconds (the manual said only needed 5) and nothing happened. i decided to leave it on the clear jumper settings longer (an hour), when i changed it back it started to boot up but froze right at the beginning with some errors (see pic). I also tried removing the battery over night and it is doing this same thing. I had the power cable unplugged when it needed to be. My system is

Chaintech VNF3-250
Athlon 64 3000+
512 Mb Kingston ValueRam
9800 Pro
40 gig 7200rpm Maxtor

What is causing this and will I need to get a new motherboard?

Also while im asking isnt this mobo have working AGP/PCI lock? When i turn it on it does not lock.

Pic of how far it will load and the messed up bios

Btw: Is this the right place for this? I put it in here because i was overclocking, should it be in technical support?

I've never actually had a problem like this, but you could try switching around where your memory modules are. That might reset the manual changes made, and fix your problem.(If you need them in the particular slots they are in now for dual-ddr, or something, don't forget to put them back once you are done).

Never seen this happened before. Don't have a a64 so don't have any insight to your problem. I assume you cannot enter into bios at all? If you still have problems after switching around your memory sticks, I'd try to lflash bios? Don't know if it work at all but that is waht I'd do.

Really a strange case. Switch off power, try to clear CMOS again, Remember to put jumper back to "keep data" position. Check connection, take out and put back (tighten) RAM, HDD cables, display card, ATX power connector, motherboard connection of cables. Then try to start your computer.

Your mobo should have AGP/PCI lock, need to check in the BIOS.

Some early 875p 865 on intel board had these problems with certain memories. My suggestion is to get some other memory and start computer. Its nice idea to keep old junky DDR memory arond just for this purpose or spare 2nd rig which you can cannibalize for short time

This is the right forum for this topic.

Your BIOS is obviously corrupted. You have two options:

- RMA the motherboard
- replace the BIOS chip yourself by paying for a new one through a website (sorry I don't have the address)

Thanks for all the help, i think im just going to RMA it. I tried adjusting all the connections and different ram and different slots and nothing. I think I may just have a bad motherboard the AGP/PCI lock doesnt work, the onboard ethernet doesnt work and now this happened.

I just had my computer die when I replaced my CPU. Not sure what was happening, but for a day or two if I moved my heatsink & rebooted it worked for awhile. Finally it just quit posting. I went through & used another CPU, different ram, etc. but nothing. I've come to the conclusion that, like SickBeast said about yours, my bios chip is dead. Never had that happen before...

I wish that were true about some of the people on the AT forums.

If you had to move your HSF, that's very strange. It should have no impact on things. It sounds to me like maybe you had the HSF mounted incorrectly and/or you didn't use thermal paste.

 

[lookin4dlz]

Yes, it was strange about the HS - I originally though the CPU wasn't seated correctly or something because of that... More than likely, it was just coincidence. I can't see a thing wrong with the board now that it's out... The old components plus a 3.0c are now in a P4P800-E humming along at 3.75GHz

Some boards require you to remove the actual ATX cable in order to remove power to all of the board(though I have only run into one of these) the bios chip somehow would power off the residual energy left in the power supply or something like that, but it would not clear unless it was unplugged.
