System won't start anymore after changing CPU cooler.

post #1 of 30
Thread Starter 
Hi, I seriously hope someone can help.

I was running my P4 3.4GHz cpu on water cooling (Thermaltake Big Water) for the last two years (motherboard: Asus P5 LD2-VM).

A few days ago, I started the system but the pump wasn't working. The CPU must have easily hit the temperature threshold because it was overclocked to 3.8GHz.
So, after trying for a few times to turn the system off then on, I gave up.

I took out the motherboard and removed the water cooling kit from my rig. I then installed Thermaltake Silent Tower.

The problem is that whenever I touch the case anywhere I feel a small electrical current running through. This was not the case before.

When I power on the system the motherboard's green light goes on and the fans all start spinning but that's all that happens.

I get a "no signal" message on my LCD monitor and I hear no BIOS beeps whatsoever.

How should I troubleshoot the system ?

Thanks.

Is it properly ground? Make sure you used all of the motherboard spacers and have it all screwed in properly. Also make sure there is nothing touching the case itself (like exposed wires ect...) It could be shorting out the board.

Clear the CMOS and try another GPU. This will rule out the GPU being dead.

Try swapping the RAM in different dimms to rule out the RAM dimms being faulty and then try one stick at a time to rule out faulty RAM.

If all of that doesn't work it maybe the board

I put an sound card on my brothers P5N32 mobo the other week, and i got the same symptoms. Everything booted and powered on, just no display.

Turned out the motherboard had gone...somehow. So that maybe your problem

Yup, certainly could. Like i said, i got the same symptoms. Green light was on, everything powered up, all fans spun. Just no display

Had to replace the motherboard, which fixed the problem. So yes, it certainly could be the motherboard. But i think that should be the last option, as it is easier to test everything else. To test a motherboard you need to buy a new one, and that would be a waste if ti turned out to be something else

Definately clear the CMOS first. My mobo usually needs the CMOS cleared after its been out of the case...no idea why.
Also check that there are no screws or un-needed standoffs that could cause the mobo to short against the mobo tray.

How do I clear the CMOS ?
Can't try another CPU and I cannot switch the system to "On-board graphics" because I can't see anything on my display to be able to go into the BIOS setup.

Well, it will depend on the mobo. There will be a jumper somewhere on the mobo. Just move the jumper onto the other pins for 10secs then put it back where it was. Its probably best to check your mobo manual as locations and procedures vary depending on the board.

Yea, it is usually near the battery somewhere.

Does your GPU fan still spin? That would be a good way of telling whether the GPU is dead or not.

Yep the GPU fan still spins.
I'll try what you guys said and get back to you on this.
If it turns out to be the motherboard then I'll have to buy a new CPU as well since the model (Prescott: 90nm) I have has been out of production for quite some time.
I hope my 4x512MB DDR2 ram modules can still be used with Core2 DUO CPUs.

You might wanna try a new CMOS battery also. Doubtful, but they're only 99 cents.
