My PC simply hangs. No restarting or blue screen of death. It simply gets stuck with the power on unless i hold the power button for a dew seconds.

Any idea what can cause this problem? This happens both at bios level and windows level so it shouldn't be a virus.

I can run memtest but the problem occurs there without any error being identified.

Finally, its not a PSU related fault as i checked with another working PSU.

I have returned to the defualt settings to make sure that it was not the overclock with no success.

Any ideas?
 
Hi mate.

Is this a new problem, or one that has always been there with your current system configuration?

Are your Motherboard drivers up to date and compatible with an SSD? (not sure if it wouldnt be, but might be worth checking out)
 
Both CPU and GPU temps are fine. The CPU never exceeds 60s under load (running stock now... till the problem is solved) while the GPU never exceeds 50s idle.

The problem appeared when i came back to Cyprus. The PC was working flawlessly in the UK. I thought that maybe it got damaged in the process, but it took about a month after i came here for the problem to appear.

The SSD was working fine in the UK, so assume that no incompatibility existed. Drivers are all current as well.

Is there a reliable way to test motherboard for failure? And is the symptom consistent with graphics card failure?

I am completely lost and i hate not being able to identify the problem! I cant fix it if i dont know what it is! :(

Edit: The overclock was completely stable for over three years, i really doubt that it would be the cause of it. I just went back to stock to make sure of it...

I did some more testing...

The PC passes memtest with 1 memory slot occupied. Tested both separetly (both pass fine). However any combination of the two causes the pc to hang.

Is this a sign of motherboard failure?
 
So the PC runs normally with just one RAM stick? Have you tried upping the RAM Voltage a tad with both RAM sticks installed?

Also try updating any Gigabyte drivers.

It is starting to sound possibly like a Motherboard issue. Your FSB is high. What were the results when you put it all back to stock?

A similar thing happened to my Gigabyte board after my house was struck by lightning BTW
 
Yeah, the PC operates 100% stable with 1 stick (regardless if which one i use). I tested with memtest and intel burn test and 3dmark loops to cover everything and it all passes fine. Thats with my previous overclocked settings.

I tried upping the VDIMM as one of the first things as i had them undervolted (1.87v instead of the 2.1v that they are specced) however it didnt change anything. I also tried upping the northbridge and FSB voltages but it didnt make any difference.

I am inclined to believe that its a mobo issue as it was occurring even before entering windows (bios level with memtest).

Putting everything at stock didnt help at all. I tried running the RAM at single channel but that didnt help either.

(The FSB is quite high yes, but the mobo can handle at least 1800FSB, the only reason i stopped using that was because the CPU temps were starting to increase a lot at 3.6GHz)

I am bit gutted to be honest, i paid god money for the mobo back in 2007 and the blasted thingie started dying on me right after the warranty expired >_<

P.s. Is a P45 good for overclocking the Q6600? I found an Asrock P45XE at a pretty good price (£65 new).
 
When you try the memory sticks, do you put them each individually into the same slot? Just thinking if you're only using the second slot when you have both sticks in, that might be the problem.
 
Tis a shame, but it does sound like the same problem I eventually got with my old P35 Gigabyte.

P45's are more than capable of overclocking a good Q6600.
Have used one myself with the Q6600 and easily reached 3.6ghz stable
 
I tried multiple slots yes. As long as two modules are inserted the PC hangs after a few minutes of stress testing.

Cheers Joe, this has been an exercise in frustration. Mobo issues are tricky to identify really. That and PSU issues are the two i hate the most.
 
Hehe, no problem mate. Sorry I couldnt be of more use though.

Unfortunately we buy into this frustration when we become PC enthusiasts.
Its worth it I reckon ;)

Hope it all gets sorted soon mate, take care
