New Processor, Now What?

[brendanh]

I wrote on this forum before asking about the following problem:

I had a 1 GHz T-bird in a Micro-Star K7-ProA Mobo (sorry if i got some letters wrong). One day I was doing whatever (nothing too intense) and the whole damn thing shut down. The fans still ran but no video signal.

I powered down and powered back up and the video came back on for 10 seconds or so and then cut out. Everything stopped, but the fans kept spinning. The actual time (of how long the video lasted) varied from 10-30 seconds but was independent of how long the computer was left off (in other words, its not a heat issue). I left it off for an entire day and the thing never worked.

So i replaced the video card (voodoo 3---> voodoo 5), and miraculously it started working again. Then it did the same thing a month later. Replacing the video card didn't work (with the old one and a new one, PCI and AGP), and every time i started up it died again.

So i replaced the processor (tbird 1 Ghz-tbird 1.2 ghz). and miraculously it worked for a day or two. Today it died again in the same manner, and i get 10-15 seconds of video before it gives up on me. I monitored the heat closely and it never got over 45 C*.

The next thing i can think of is replacing the motherboard. I don't want to go and replace every *$#@() part until something works permanatly. (BTW RAM and all other components are NOT the problem, it does the same thing independently of any devices installed/unintstalled).

Any ideas? Sounds like the mobo is the problem.. but could it be that the mobo is the thing that burns out the processors so when I replace the mobo it still won't work without replacing the processor AGAIN?? I'm out of cash and patience.

Thanks people.

Sounds like a motherboard issue and hopefully only a motherboard issue. Get a new motherboard and try it out with the CPU you have now and hopefully you won't have any more problems.

Could be a short in the mobo and it takes out the other components... I've heard of lightning strikes doing this. It'll hit, but nothing's the matter until two or three weeks down the road. Then all of a sudden weird things start to happen. The fact that the new parts go out soon after they've been replaced makes me think that its the mobo.

I had all kinds of wierd random shutdown problems with my MSI K7T Pro 2a. I seemed to fix it somehow eveytime, but the problem would come back. Somehow, messing with my CPU bridges would fic it, so I thought it was my CPU. I also bought an Athlon 1.2, but the video would only stay on for about 10-15 seconds. It finally died about three weeks ago. Now I'm running ultra stable with no issues on an Abit KT7a-Raid, with my Athlon overclocked to 1.4ghz. I'm pretty sure it's your mobo, since I had the exact same problems as you.

You are my HERO! I was waiting to get someone w/ the same problem!
I just ordered an IWILL KK266. Hopefully everything'll be cool now. Thanks for you reply!

Oh, so i'm not your hero anymore.. Looks like everyone thinks it's the mobo though.
Kinda sucks you had to go through all that to figure it out it was the mobo the whole time.

Oh well.

LMK when the new system is up and running
