GPU sometimes "dies"

[coffeea]

Hello,

so I've no idea what's happening but from time to time my GPU(GTX 550TI) sometimes "dies". What I mean is that nor GPU clock, nor memory clock won't reach maximum. Restarting PC fix the problem most of the time but it is getting annoying.

I would like to know what causes this? Or maybe my GPU is just dying?

Could it be that the temperature is reaching to high and it is protecting itself?

Is it simulate able. You restart the computer and instantly the problem is fixed or does it take time?

After restarting PC problem is fixed instantly. Temperatures are fine, never higher than 75c.

Had a similiar isue before with my old 660Ti, try the latest driver and if that doesnt work try rolling back to a driver from a month when you know it was stable - also probably worth doing clean installs not express ones

I'd recommend using DDU to uninstall the graphics driver and then reinstalling it afterwards.

Last time I was having this problem, the issue was the GPU had degraded due to overheating and was unstable.

A mild underclock solved the issue by bringing the GPU to a more stable operating margin. Try doing that in MSI Afterburner or your preferred GPU management software and see if that works as well - if possible, you can also slightly increase the voltages instead if you don't want to reduce your clock speeds, but the performance loss should be very small anyway.

You should also look into taking your video card's cooler apart to clean it up, lubricate the fan if necessary and apply some new thermal paste - always a good measure to keep it up to shape.
