first buildpowers on but shuts off soon after

[flipgee]

it told me the cpu was shut down due to a thermal event(over heating) everything works for like 30 seconds tho i can get into the bios but it shutsdown soon after... any ideas


the processors fan is plugged in

[doctorgonzo]

What are your system specs? It sounds like a problem with the heatsink. Did you use thermal paste or a thermal pad? Is it the stock heatsink or did you buy your own?

i just used the heatsink stuff that came with it looked like a sticker
i cant imagine i fried anything if it still comes on

[doctorgonzo]

You won't fry anything because the processor will shut itself off before it destroys itself.

Those Pentiums are tricky in terms of getting the heatsink on fully. I'd retrace your steps and make sure it is firmly attached; it can take some effort.

the heatsink is the thing kinda next to the processor right it looks like bunch of pins on a metal rectangle?...it was already installed on the mother board

[doctorgonzo]

No, the heatsink is what you put ON the processor. If you don't have a heatsink on the processor then it is no wonder it is shutting down!

I believe the heatsink you are referring to is the Northbridge chipset heatsink. The one Dr G is referring to is under the cpu fan. It's a large block of finned aluminum. The heatsink/fan (hsf) assembly is held tight with 4 pins that have to be pushed thru the mobo in order to apply proper pressure to the heatsink. Here's the Intel manual on how to install the hsf.

We are also assuming you left the thermal pad attached to the hsf when you installed it. And that you didn't add any additional thermal paste or compound.

yes there is a heatsink and fan and all that good stuff on the processor and i didnt mess with the pad on the cpu fan cuz i heard that was bad....i just tried to power it up with the mobo on a noncondunctive surface outside the case but that didnt work either it again shut itself off after about a minuete...theres a red switch on the back of the psu with 230 and 115 v on it could that make a differencei have a coolmax 500w psu and heard that some dont really run as high as they are spossed to could that do anything...also i hear something about the jumper on thte mobo but the only on i see is for cmos i think...grrrrrr

oh yeah and the spacers people are tlking about for the mobo are they only plastic or are there metal ones too?

[doctorgonzo]

The switch on the PSU should be set to 115 V in the U.S., 230 V in Europe, but that's probably not causing the problems. If you are still getting thermal event failures, then take a closer look at the heatsink.

ill do that this afternoonmaybe just buy a new cpu fan all together...on a side note my old rig that i was using to ask you guys questions crapped out for no obvious reason this morning...CRAP... but i will try a new heatsink maybe even thermal paste...thank you guys for your help i really appreciate it

[flipgee]

i got some thermal grease and took off the stock thermal pad (compusa sold me the wrong part again(cpu fan)) but that still didnt work but i think it took a little longer to shut off this time and the mother board right behind the processor was almost too hot to touch...my bro is gonna be back in town so hopefully we can figure it out if not im just gonna pay some dude way too much money to just do it so i can stop pulling my hair out

[doctorgonzo]

Did you follow the instructions in the link that Panama Red posted, making sure that all four connectors were securely fastened down and that the heatsink was making good contact with the processor with no gaps? Did you use the right amount of grease?

[flipgee]

yeah that turned out to be the problem i thought they were in good but my brother found that one was not in all the way...thanks again for everyoones help i am currently typing from m new computer ...see you all on the battlefield soon
