PC Boot Up Problem fro Overclocking

[WAnderson]

Hey All, I've got a problem I just can't seem to fix. I attempted to increase my front side bus, and the next time I booted, all I got was a blank screen and 8 beeps. When i tried to overclock, all I did was pop up the fsb to about 75 with the multiplier at 3 (No I didn't exactly know what I was doing at the time, trust me I've learned my lesson http://www.PCGuide.com/ubb/tongue.gif Now I thought I could've friend the processor, but I tried it in another system and it was ok. According to the AMI Bios beepcodes, this has something to do with the system video memory, which has me *really* confused. The system is a P166 with a MB571 (PcChips) TX Pro II CHipset Motherboard and about 40 megs ram. I took everything out but a PCI graphics card. It does have onboard video and sound, but I haven't messed with it much. I've found specifications on the net about a jumper to diable to onboard video, but that didn't seem to do much...any ideas?

If your question is how to get the system back up again......the answer is either find the "clear cmos" jumper and put it on "Clear" setting and restart system for about 5 seconds...then put it back to "Normal" setting and restart or pull the cmos battery (quarter sized silver battery visable near where PCI cards go . Pull it out carefully and leave out for about 10 min.....reinsert and you will be back to default settings and can start again.

Try using the on-board video to POST and get into BIOS setup, You may have inadvertantly disabled the video card and not the on-board video. If you can get into setup the you can also reset the defaults thereand maybe then diasble the on-board video.

Ok, I'll give it a shot...

Ok, I had the battery out for a couple of hours (took it out before I left for school) but had the same problem. Tried the clear CMOS jumper too. I think I forgot to say that the overclocking was done by jumper, not through the BIOS. Think I killed it?

[Randy_tx]

You might have.......especially if prior to clearing cmos you returned the jumpers back to factory settings........You DID do that didn't you??? The jumpers MUST be correctly set for that cpu to get a post up....otherwise you might have overheated the cpu and burned it up if you DID put it back correctly prior to trying to post.

I think I reset everything right. Quick question, and this will sound incredibly stupid, by CPU you don't mean processor, you mean the BIOS etc. right? I've already checked the processor and that seems ok...

Nope, CPU means processor. BIOS is the CMOS chip. Completely different animals. CPU stands for Central Processing Unit. CMOS is Complimentary Metal Oxide Semiconductor, it's the chip the BIOS information is stored in. The battery supplies power so it can keep the stored information while the computer is powered down.

The good news is that a new P-166 is less than $30 if you can find one and your Motherboard is probably OK....but you might have toasted the RAM modules or the video card, rather than the cpu .... so you need to try this routine(assuming you have cleared the cmos):
1. Try different ram modules & try to post
2. Put a different video card in & try to post
If these two dont work.......it's either the cpu chip or motherboard or both are gone.
