System wont boot after setting jumper

[JsN]

Hi
My pc wont boot,it keeps making a continuos beeping ,and there is no video.

The pc worked fine until I opened it to fix several things...I overclocked the K6-2 processor from 350 to 450mhz, enabled KBPO in the EPoX MVP3G-M motherboard, and I set the memory clock jumper to the CPU clock (it was set to AGP,wich is 2/3 cpu clock, but the memory is PC100). Now the pc keeps beeping continously and there is no video at all. The bios is award, so i suspect a memory or video error. I dont have another PC to test the memory on...

Now im trying to boot the pc with only the hard disk, the floppy and
my Matrox mystique video card. Im not sure about if the memory is blowed up or if it is a power problem of any sort,because I notice the power supply making less noise that it used to,or at least that seems to me, but well im not an expert... the video card works,the monitor works,the processor worked at least until I opened the case...
now it doesnt bot even with the memory jumper in its original position, neither removing the overclock.

well thats all...i will appreciate any suggestions, thanks

A continouse beeping is usually a cpu alarm (high temp, low voltage ect) might have toasted your chip.

Continuous beeps is video or memory problem. BIOS beep codes (http://www.pcguide.com/ts/x/sys/beep/index.htm) from PC Guide has info on lots of the beep codes. Both Award and AMI show continuous as being video or memory problem.

Sounds like it's time to get new memory or video card, I think you fried one or both overclocking it. Try the video card in another machine, I think you'll still get the same beep code. If you have a friend who won't mind, you can boot it just long enough to get video or hear the beep code, and you won't have to actually install the card in Windows, shut it down quick though...

Same applies to the memory, the only other way to test either is to take them to a computer shop and have them test it.

One maximum recommended overclock for a K6-350 I saw was 420, with 400 being the typical, so it supports Nunjo's thought.

This PCGuide (http://www.pcguide.com/ts/x/sys/beep/awardContinuous-c.html) link says that while a continuous beep is most likely memory or a video problem, it could be a system board problem too.

Good point Reid, I forgot about that, could be motherboard too.

I'm still betting on video card or memory though, just seems to be more likely.

I looked at the EPoX site to see if they had anything else on the beep codes. Here is their short list of common codes from the FAQ section:

one long and 3 very short beeps - video related
continuous beeps - memory related
no screen and no beep - CPU related

JsN could also try moving the clock speed down a bit. I must have a knack for buying marginal memory, but I have put three systems together, one Tyan and two EPox', but none would run with PC100 memory and a 100MHz clock. Just dropping to 95 or 89MHz corrected the problem.

Again, a tip of the hat to Reid on a job well done. Epox is not the only board that uses one long and three short for video errors, I've seen that one...or heard it actually...even on XT boards, and would have recognized it instantly. Some also use continuous, and I thought CPU would be none, but wasn't going to say so without being positive. And by the way, thanks for saving me the trouble of looking it up. http://www.PCGuide.com/ubb/biggrin.gif Thought of it after I logged off yesterday...

As for your experiences with PC100, that's not exactly unheard of, although not a highly common occurrence, especially with generic RAM. With the major name brands it's less of a problem, but sometimes the RAM will work fine if underclocked a bit. I wish I could remember where I found the info, sorry I can't post a link...

Pete, no need to find that link, I'm a believer from experience http://www.PCGuide.com/ubb/smile.gif
I was even expecting that problem after the building the first system, but at the time PC133 was too expensive and I decided to give up MHz instead of $$$.

Coincidentally, I opened up a spare computer yesterday to check out some DIMMs. I kept trying different memory combinations, but it kept beeping. It turned out that the video card had failed, but I had convinced myself for an hour that it had to be memory related because the video had worked the last time it was turned on. I finally looked up the beep code http://www.PCGuide.com/ubb/smile.gif

LOL...

Got ya beat though...When I was first learning computer repairs, I once spent an hour trying to troubleshoot a computer that got no video on boot, when it worked perfect earlier in the day, I forget what I did to it...upgrade a hard drive or some such...anyway, a friend finally walked over and turned the monitor on...AFTER I tried 3 video cards, two memory chips and a different power supply...
