Overclock causing GPU to switch off

Lethagized · 25 Jul 2011 at 04:15

So my system has been overclocked and running stable for many months now, but it's recently and randomly started to crash in games. Sometimes it will do it within a few seconds of starting a game, other times i could be half hour or an hour into it and it takes a ****. Sometimes it won't crash at all. When it does, both monitors lose signal which puts them into standby and i have to hard reset the pc to recover it. The sound is still playing in the background sometimes. Other times, i get a looping crashy sound.

GPU and CPU temps never go over 70c

Any ideas?

It doesn't have to overheat to be unstable.

I'd start by removing all overclock and making sure it's stable without.

If its fine then add your overclock in steps til you find what makes it crash on you.

Sounds like a sketchy video card. Had the same problem with my box "white screening" in BFBC2. Make sure you're running some good GPU fan control software.

my video card does this when i push it too much, you sure yoursu can supply enough power to do it? as mine kept resettng the pc bu t was due to the psu not being powerful enough

It's not switching the GPU off, the CPU overclock is unstable. Lack of signal!=caused by GPU

Just back the OC off a bit and you should be fine.

Forgot to mention that the GPU isn't overclocked at all. Will try backing off the clock on the cpu instead and see how it goes.
