Possible f*ck up

Anima

Hey,

Recently i was cleaning my fans including the heatsink one. So i took it off but i realised i had made a mess of the thermal pad. So i decided to buy some proper thermal compound in Maplins. I got some Cooler Master branded one for E10.

Anyway, few days later i decide to apply it. So i take off the heatsink and remove the thermal pad from it. There was only a few dabs of residue on the cpu so i left it. I put the compound on the heatsink as instructed and placed it on the cpu. The instructions were a little old and I was supposed to line the template sticker up with the heatsink clips, but i have a p4 and it has that rectangle bracket thing to slide it on, so i wasn't sure if it was in the right place. When i had placed it on, i took it off to see if the cpu was covered in goo, which it was luckily but now there was places where there was no compound . When i turned my comp on, it took only a few minutes for the temp to reach 70 degrees. So i immediatly turned it off.

After this i decided to re-apply the compound smoothly and properly. After i did this i left the case open for the night to let the stuff do its work. So this morning when i put it all back together, I ran into some problems. When i turned it on, it took 10-15 seconds for the computer to turn on for some reason and when it did, the monitor wouldn't turn on and i wasn't getting a post. I reset the cmos then for some reason but it still didn't work.

So I'm guessing the cpu is fried but i thought the P4 had some safety features like it would de-clock itself after a certain temperature and also I'm using an Abit board with the temp. monitor that comes with it and thats supposed to be 10 degrees higher than in reality. Surely it wouldn't fry at 60-70 degrees :dunno:

So is it off to the shop to buy a new cpu or could it be something else?

Did you use a electrostatic strap?

Or ground yourself beforehand?

Sounds more likely to be zapped than fried cpu to me...

No chance a blob of HS compound got over the cpu socket?

Card seating? Try reseating all the cards just in case.

Ditto for psu connections.

Is the mobo beeping - if so check what the beeps are on google.

Anima

Yeah i grounded myself every time i was about to touch something with the radiator beside me.

Atm all i have is a gfx card, the mobo, ram and cpu in and still theres no monitor action .

Theres no mobo beeps either.

Oh thats sounds bad, make sure 100% you have everyhting connected right (LOL i have on one occasion for forgot to plug back in the heatsink) then when you positive it all connected and still wont boot, borrow a CPU if possible in case you fried the mobo rather than the CPU.

Intel chips won't fry with overheating. They'll just shutdown.

Sounds like you have a different problem. Are the CPU pins alright ? Is it getting enough power ?

Loobz

Something similar happened me. Except I took out the graphics card.

Basically I took out my graphics card to clean the fan and put it back in. when I did, the windows logo came up but immediately my monitor went blank and the monitor went into stand by. I went into safe mode and reinstalled drivers - sorted.

Also for some strange reason, if u plug your monitor into the second output on your card (supposing you have 2) it may not display anything on the screen. Swap it to check.

I dont know if this will help but maybe it will.

Anima

Shouldn't my gfx card display the bios screen even if the cpu was fried?

One day my CPU fan stopped while i was running it under load. Winbond measured 90'C before I pulled the power cable. (Auto Shutdown was slow). Usually the motherboard would beep if they was a problem with any essential component not present. Check all connections again. That 4 pin power connector might have come loose:dunno: My Abit IC7-G has a green power led on the board itself. It should be one once the PSU is on and connected.

Anima

The green light is on i'm afraid

She just wont boot damnit!

Dempsey

Does the red one come on at all?

Explosive_Cornflake

What does the 4 pin power wires do? (badly phrased i know)
I was building my athlon system a few months ago, and i couldn't find the 4 wire power lead for the mobo, si just thought, oh well, there's none on the PSU. Wired everything else up, and computer works fine, and has done for months. The other day i was bored i decided to tidy up the wires, and *wow* i found the power lead hidden behind a drive bay, plugged it in, and i see no difference. Its that 12 vdcc or whatever its called.
Is that a bit strange or normal?

Dempsey

Its a connection for P4 systems, not used by AMD CPU's. It a 4 pin, squared(2x2 pin) yoke, completely odd to everything else

Anima

Yeah the red light turns on when the comp eventually starts. Still no picture though

CyberGhost

when you left your computer to cool off did you cut the power to the psu?

I had the same problem! athlon heated up 75 ! then I tried to run it and it didn't! then i cut the source and after couple of minutes tried again, and it started working!

SouperComputer

reset cmos? just to ask the obvious question!

clean off all the thermal compound from the chip die and the heatsink.

apply a layer of paste to the surface of the heatsink, apply to prepared heatsink to chip.

koneko

Aye, he speaks the truth.

Use nailpolish remover and remove all trace of the compound from heatsink and cpu. Then apply a little bit on the cpu, spread it out using a blade (preferably) so it's a thin layer. Make sure the heatsink is applied correctly.

Reset the CMOS, take out any extra cards (so there's just one stick of ram, HD, graphics or use onboard) and see do you get any beep codes at all. Recheck all the cables/connections.

Not entirely correct I'm afraid -

My Abit NF7-S 2.0 (AMD board) uses this ATX12V connection.

Explosive_Cornflake

Yeah, its a abit AN7 i have, but it made no difference when i plugged it in.

As does my dual MSI K7D Master


The 12V connector is to provide a clean reference 12V rail instad of a 5V, along with some extra power for the board, cpu, ram, fans and graphics card.
The reason it's 12V instead of 5 is because it's easier to derive a 5V rail from a 12V source than to make 12V rails from a 5V source, and you'll end up with a "cleaner" (read: less variations, won't go wild under load) rail.

It's part of the ATX12 standard.
