alright well i had searched and found a similiar thread to this, but was unable to solve the issue. I made sure my MB was on a non-conductive surface, and i still had problems. So i wondered if it was the Power supply... I didn't have an extra power supply so i tried something that really gave me direction to my problem. I took off the heatsink and took out the cpu. I then turned the computer on and power stayed on. I do have the thermal pads there. It is a brand new CPU. Something is just telling the computer to shut down and i'm confused what exactly it is. Any help would be greatly appreciated. One last note, i did double check to make sure MB and processor were compatible, they are both set for athlon xp. thanks

Hello ryanb2983,

Welcome tohttp://www.pcguide.com/ubb/pcgubb.gif Forums!

Was it the post regarding the processor fan and the correct motherboard header to plug it into?? Or, the one with the correct header being used, but the fan connector placed backwards??

Was this computer ever working properly?? Is it a new build?? A new purchase??

You could look at the link below to help check out the PSU but you need to supply more details as Whyzman suggests.

this was the post I was referring to, by user bubbaj

This computer was working, but the chip went bad. The reason i knew that is because i had borrowed a chip and it booted up. So i got a new chip for the computer, and it keeps powering down on me for some reason. I get no post, nothing on screen, no beeps, just a quick powerdown. I know for a fact it isn't the power supply as I mentioned before. So i don't know if between connecting something, that i messed up somewhere or what?

thanks for the replys or any help!

If we're talking about identical chips and it powered up...it sounds as though you've a bad CPU...

Or, the dreaded ESD might have come a knocking...:( Takes about 2000 volts for us to feel a static discharge...about 200 volts to turn many electrical components to toast...:eek:

If you can get the borrowed chip back and verify, or are certain proper grounding procedures were used...you may have found the culprit...

You may want to clear the CMOS and enter the BIOS to reset the default values also...

Ya I am almost positive the CPU is either fried or bad to begin with. Im just going to end up sending it back as it is brand new. And this was the identical chip I had used earlier. I was just curious if anyone had any suggestions that would maybe solve it. Thanks for the concern and help though! appreciate it

Unfortunately, computers have no gliding ability...if the motor is shot the trip to earth is pretty instantaneous! :eek:
