Computer Starts then Stops in an endless cycle

post #1 of 9
Thread Starter 
Asus P8P67-M / i5 2500K

If I put the memory I get endless ON-OFF cycle. If I remove it then it works as intended.

I've tried another ram module with all slots, which are clean.
I've removed the battery for 30 minutes to reset the BIOS.
I've tried another PSU - same thing.

Here's a video of what's happening: http://www.youtube.com/watch?v=T2Ujsz7_S9E

1st half is without memory and 2nd half with memory.
Btw is the noise coming from the water pump normal - it sounds quite loud and annoying.

Anu suggestions what might be the problem?

Hi,
I would check asus and see if you might need to update the bios to run the RAM your trying to use. Also, it could just be a bad ram stick....

Btw I removed the water cooler and things doesn't look good. It looks like it has leaked:

So it is either the Mobo or the CPU - is there a way to find out without having another CPU? I have a multimeter.

If it was me, I would just pull a old heatsink/fan and see if it would work. Because then it was just throttling down each time and repowering to try to save the cpu.

I've tried without a heatsink for a very few seconds, while monitoring the temperature of the top of the cpu with an IR thermometer = same thing.

When a memory module is installed = starts/stops
No memory module installed - runs without stopping.

Logically this should mean a problem with the CPU as the memory controller is built inside it, right?

nono, I meant find a old heatsink, and use it. If anything was bad, it would be due to your cpu overheating. To me your motherboard sounds fine. In the first part of your vid in tones once long, then two short, meaning video or ram.

The 1 long 2 short is problem with the memory which is fine and expected as I've deliberately removed the memory.
I think it is some sort of protection: it shuts down immediately after it is powered on.

I just want to find out what to buy: CPU or mobo. Maybe I'll risk it and get a cpu.

its shutting down because its overheating ....I'm saying you might have, might have mind ya, got away without hurting the cpu...If ya stick a old heatsink or what have you , it might be fine. But sometimes the overheating can also kill your motherboard

It was shutting down with the leaky heatsink + it is not shutting down with no memory installed = doesn't seem like overheating is the cause of shutting down.
