PC wont boot after RAM test

[Rsundvor]

Hi!

 

I have recently had a couple BSODs daily, and I thought they were memory related (Memory_management error, and Kernel_security_check_failure). So i decided to run Memtest86. So I booted it up, and watched it for a couple minutes, and went away when it had 9 errors. When I came back it had crashed (nothing was running, couldn't press anything) and it displayed about 75000 errors. 

When i tried to reboot, my PC starts for 19-20 seconds, and then it reboots itself. There is no signal to the monitor on either of the boots, so I can't even get to the BIOS, nor is there any beeps from the motherboard.

 

I have tried to reseat the memory, and even tried some other sticks of memory, but no difference.

 

I installed a H100GTX watercooler, and an EVGA GTX980ti yesterday, but I ran several games and even a CPU stress test, so it all worked fine.

 

Everything worked as usual, untill i started the test, I think it said it was 75% done when it crashed.

 

What can be the issue here? Please help!

 

Specs:

CPU: i7 2600k (OC'ed)

MB: ASUS p67 Sabertooth

Ram: 2x4gb Corasir Vengance 1600mhz

Video card: EVGA GTX980ti

PSU: Corsair GS800

Storage: Corsair (something, something) 60gb SSD

               Two 500gb hdds

Case: NZXT Phantom

Cooling: Corsair H100GTX

 

 

UPDATE:

For some reason, when I have only one RAM stick plugged in (No matter which slot) it works. I can boot as normal. If I plug in two sticks in don't, even if I use two slots that have been tested to work fine with a single stick. 

The other weird thing is that if I have sticks in slot 1 and 2, it reboots. If I have them in 1 and 3, it does not reboot, but it still wont go to BIOS or post anything to my screen.

What can I do to get two slots working?

Did you run Memtest with only a single stick of RAM? If not then you will need to do so, the errors you got could have been due to either dimm.

I am not able to get to BIOS at all, nothing is displaying on my monitor. So that is not an option.
