GPU core clock goes down to 135 mhz

[PCproblemos]

So here's the case: I sent my computer in to repair the hard drive. The repair is gonna take more than 5 weeks which is a long time for a hard drive replacement. They did however have the courtesy to lend me a computer for the time being.

And I'm having problems with that computer. When playing games, after a while (this time varies from 1-50 minutes) the gpu core clock goes down to 135 MHz causing unplayable framerates. My temperatures are low (40-50 celsius) and I haven't done any overclocking.

List of things i've done:
Deleted and re installed drivers.
Run virus scans.
Factory reset computer.(and re installed games).
And some attempted tweaks in MSI Afterburner.

I am far from an expert when it comes to things like this, so i may very well be missing something simple.

Help would be very appreciated!

are you sure those are your gpu temps?

I'm pretty sure those are correct, yes. It's a fairly cool laptop and i'm using a cooling pad. The air that the fans blow out isn't very hot.

Temps were monitored with MSI Afterburner and GPU-Z

and the temps are always that low? even before it slows down, it all points to thermal throttling, and i've never seen a laptop running that cool on discrete graphics. I've never seen a cooling pad do more than 1-2 C of improvement, certainly not the 30-40C that you might need to have those temps being normal (according to my experience).

Yes when i'm getting 50+ fps in gta 5 the highest temperature i got was 62 celsius, and that was after forcing the gpu to work on full clock.

I think i have a clue what the issue is: When the fps drops, the clock speed of the gpu is ALWAYS 135 MHz and doesn't sway. This is interesting because 135MHz happens to be the clock speed during GPU idle. So maybe the GPU thinks that it is rendering the desktop? I dunno.

About the temperatures, yes i agree laptops using discrete power sucking gaming cards tend to go 90 celsius + in my experience too.

u find solution ?
