Possible causes for freezes?

post #1 of 8
Thread Starter 
Me again biggrin.gif

Quite recently I have been having freezes mostly in high running games. The screen freezes, the HDD light stops blinking and I hear all the fans go on default speed. Combined with artifacts I presumed this was my GPU's fault so bought an 6950 (unlocked to 6970 now) however I have already crashed a few times in Crysis and Dirt 2 frown.gif The same way as before.

I was thinking that this could be a heating problem? On clock speeds my unlocked 6950 is at 54-55c and OCed it gets to around 58-60. In games this is getting up to 70-80c (can be lowered by manually taking control of fan but anything above 30 per cent sounds like a jet engine).

My current case is a HAF 912, it has one 200mm intake front fan, an 120mm exhaust, and two top 120mm exhausts which I installed.

Idle, the CPU temp is 35-40c and motherboard temp 30-35c.

This is happening on both XP and 7 (on different partitions)

Soooo yeah I'm pretty stuck on what's causing these crashes, is it the high temp of my GPU? Or maybe my intake/outake fan set up is out of balance? Or maybe my 580w PSU is dying and forcing crashes?

Any ideas would be very much appreciated redface.gif Knowing me, it's probably something very simple.

I vote psu or a bad ram stick. Can you take the ram sticks out one at a time and see if the crashes continue? If you do that make sure the ram stays in the right slot for the new ram configurations you will be making.

Under load it gets to around 50-60c. I have taken out one of the RAM memory sticks and I haven't had a crash as of yet, although I've noticed that I can have periods where it doesn't crash for a while then suddenly hits a crash attack. Weird thing is, I took it out after a freeze yesterday, where I would normally be greeted to the message 'your active desktop has been stopped' or something along those lines, this message didn't come up with the one RAM stick, any significance you think? Anyway I'll keep the single 2gb RAM in for the time being, do hope that it is the problem so I will only have to replace one stick and not another component.

Found out it wasn't the ram as both sticks crashed on 3DMark11. Yesterday this seemed to stop when I changed the sata ports for my HDD and disc drive, however now I am getting the same problem when trying to run Crysis. I reverted my unlocked 6950 back to its original state but the problem is still there. I used http://www.techpowerup.com/downloads/1920/HD_6950_to_HD_6970_Flashing_Tools.html to unlock and revert it, I think that program uses the Sapphire bios, could that be causing any problems with my XFX (I tried flashing back to the original bios but winflash errors). I've also noticed that the 6950 temps have gone up by about 8c since reverting it :s despite running at lower clocks.

I've put the 6950 and Q6600 both back on stock speeds, but could it be my 580w PSU cannot handle the load? It's a rather budget one. I've also installed a side fan facing the GPU which has reduced its temps a lot.

Pretty stuck here frown.gif Part of me is tempted to splash out on a new sandy bridge system. Any thoughts would be very much appreciated as I'd rather save some money.

Edit: just got another freeze after posting this.

Are you sure that you're 6950 isn't overheating? The only time I ever get 'your active desktop has been stopped' is when my video card gets too hot and I forget to turn up the fan.

Yeah I monitored it in game once and it got to 44c before freezing, doesn't seem to get much past 65 in other cases. Idle speeds are now 30-40c. I just had a chat with a friend and he seems convinced it's my PSU.
