Computer Starts then Stops in an endless cycle

CYPER · 6 Sep 2013 at 22:53

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?

Can you list your system spec, as this may help others help you.

Don`t understand this bit, can you clarify what you mean, as it does`nt make any sense.

Is that the red dram/mem ok light lighting up? What make/model memory?

2 beeps Memory parity error. The parity circuit is not working properly.

Check for Bent CPU socket pins? It will beep if no memory is installed

I'm just testing the Mobo/CPU/Memory as the problem is definitely in one of these.
Check the video - with the memory installed the computer starts then shuts down immediately and this goes until I switch off the PSU.
Without the memory installed (just PSU, Mobo and CPU) - computer starts and runs normally, just beeping for missing memory.

It is (DRAM_Led) and according to the Manual:

Memory is Patriot PSD32G13332

It is 1 long, 2 short, which I believe is problem with memory, which is to be expected as I remove it.

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.

CPU pins look OK.
Now I'm convinsed it is leak damage - I just have to figure out which one is dead - CPU or Mobo.

Let it dry out first,then try again,can't see pics yet,not showing up on my phone

Pics are up. You mean dry the CPU, because I don't think it is a very good idea to use the CPU cooler again as it is leaking.

Don't you have stock Intel cooler? I mean take chip out and leave everything a few days to dry out,last thing you wanna do is power it up whilst wet or damp and have a short circuit

Can I dry the CPU and the socket with a hairdryer?

Looking at that pic of the Cpu, there looks to be a cluster of damaged pins, in the top left section.

wazza300 · 7 Sep 2013 at 01:02

yes but don't stay on one spot too long or get too close as it might melt the plastic or bubble the pcb of the motherboard

it could have shorted the memory sticks,ive had that happen with a bent cpu socket pin

EDIT post a pic of the whole cpu socket/pins from directly above looking down on them

I don't see anything unusual.

When I shine strong light onto it I can actually see some strange coloration:

wazza300 · 7 Sep 2013 at 01:40

does it rub off? clean it with thermal paste cleaner or alcohol

cpu's are pretty tough,if dram led is flashing it could be the memory itself or the integrated memory controller inside the cpu or something to do with it

wazza300 · 7 Sep 2013 at 01:51

hold on,im seeing no graphic card??

it wont boot or display anything with no gpu installed,p67 has no onboard graphics support

I have ArctiClean Thermal Paste Remover and Thermal Surface Purifier. I'll try with them, even though when I look at it I don't see any difference.
Just when I shine strong light and at an angle.

It's either the CPU or the Mobo as I've tried with another RAM module and no difference.

Do you know anyone who would be willing to give me a processor for a test - any socket 1155 will do. I'm based in NW London.

The problem I'm experiencing is not realated to the video card. The system automatically shuts down with a memory module installed - it doesn't even get to POST.
