OC gone bad?

I was playing around with an old system i had laying around, i went into the bios and realized it had the capabilities of oc'ing, so being a novice when it comes to oc'ing, I punched the cpu clock to x8.0 and the pci/ram to the highest(couldn't tell ya what it was, cause i don' remember)...after I did this, the computer rebooted when I got out of the bios like it should, but I had no display...the monitor light stayed that yellowish orange...but the computer is running....I tried both the onboard video and video card, and neither respond.....so...is there a way that I can reset the multipliers to there defaults, so I can try it again the right way....it is some old CompUSA PC (yes, the brand is CompUSA), that has a Plll @ 600MHz (which is what it is suppose to be running at).....I don't think I fried anything because the computer still turns on and is running...I think I just punched pci clock too high...I really don't know the specs on the mobo, don't know if that matters :confused:
 
try finding the battery on the motherboard, and taking it out for an hour, then put it back in, that usaly resets the bios settings. also, look for a reset jumper on it.
 
Yeah, that's a textbook over-overclock (think about it...it makes sense). Take a gander at OC101, that'll teach you everything you need to know. If you're too lazy, or are being chased by a rabid bloodthirsty amishman (that tends to consume much of one's time, in fact, too much to be able to read OC101 in one sitting ;) ), I'll give you a trimmed down, case specific, version.

First, try not to mess with the PCI/AGP bus', that's not the best idea when you're new to OC'ing. Now, after you've reset the CMOS, if you still have your heart set on overclocking it, try pushing the multiplier up by the smallest increment possible (hopefully 0.5), and when the computer stops displaying anything on start-up, reset the CMOS, jack the vcore by 0.25v, and try again. Once you have what you consider to be a decent performance gain (if it has a thermal diode, check the temp readout in the BIOS just to be safe, although, with a P3 600MHz proc, it should be fine unless you're trying to pull a heinous, ungodly, overclock), check the stability of the OC with Pi-fast, or other such programs, and if it's stable, hooray, if it's not, then either jack the vcore and try again, or go for a more moderate OC.

Again, I recommend actually reading OC101. That's the best guide you could ask for, and I didn't write it, so to most people it's much easier to understand than the coded jumble that I sneeze into semi-cohesive jimble-jamble.

Edit: You don't need to take the battery out for an hour to reset the CMOS. If there's a jumper to reset the CMOS, switch it to 2^3 pins for about ten seconds, then back to 1^2. If there's no such jumper, then just remove the battery for about ten seconds. That's what I do, and it's never failed me.

that never a good idea, new to oc'ing or not :)

You need to unplug it as well :)
The cmos jumper will be on the board somewhere look for is (cmos is basically another way of refering to bios)

So praetor is not your pen name???

Plll @ 600MHz

Good to play around with but dont expect a huge oc with this bad boy.

As recommended, read oc101

the reset jumper works in 10 seconds, look for that, insert a jumper, and go again ;)
 
alright, I reset it, now I started oc'ing agian, I got up to x4.0 but....it doesn't say that my core speed has changed at all?!?!?!?....is there a certaing program I need in order to see the actual speed it is operating at?
 
Well I could see the results when I OC'ed in Control Panel->Performance and Maintenance->System...
