GTX 980 help - performance declines after reboot

[johnno]

Hi all, I have a friend who is having issues with his system. please see the 2 3dmark links. The higher score is straight after a reboot. What do you think could cause the low score?

edit: Got it, okay performance after cold boot / reboot, then perf declines with time. Not that there is a difference between cold and warm boot.

Hi, so all has been OK until recently. But now on a reboot / cold boot of the pc gaming performance is great. After the machine has been on for a while the performance drops.

Check it for malware. Also check temperatures.

Could be your cpu HSF is full of dust and over time the heat builds up and it throttles.

Ah, now it's clear. Yeah check for malware. I don't think it's temp related if a reboot clears the issue for a while. Are we talking GPU performance, or also CPU performance drops?

Looking at the 3dmark results it is just gpu.

Graphics Score 9500 Graphics Score 18669

Physics Score 12341 Physics Score 12233

Combined Score 9515 Combined Score 11562

Run MSI AB and see if GPU usage sky rockets after a while. Then something is stealing your GPU cycles. You can also check if it is clocking correctly during the "slow" run.

OK thanks, I'll pass the help on.
