100% GPU usage/Low FPS first boot?!

So I've had this problem for a while now and I've usually just been dealing with it by restarting the PC after every first boot of the day, but it's starting to become a pain now and I'd like to know if this is fixable or the card is just faulty and needs to be RMA'd. The card I have is an R9 Fury Tri-X by Sapphire (note, not the Fury X) and obviously it's still relatively new so I haven't had it for that long. The problem I have with it is that on the first boot of the day it seems to make the computer run incredibly slowly - FPS lag on EVERYTHING, not just in games. Browsers are slow, there's lag in the mouse movement, and basically a whole plethora of problems arise until I reboot the system. Upon a reboot everything usually goes back to normal. I checked Afterburner on my first boot and noticed that GPU usage was constantly at 100%, but the temps weren't affected at all. Clocks were (understandably whilst not gaming) underclocked also.

Things I've tried:

- Virus/malware scans
- Complete uninstall and re-install of latest drivers
- CCleaner etc.
- Repair of SSD


I'm not sure what else I can do? The 100% usage on first boot leads me to believe it's a problem with the card itself; I had another problem with it whereby it would be running constantly at around 60-70 degrees whilst on desktop (it's supposed to be a 0db card) which was only fixed by setting up a fan profile inside of afterburner to constantly have the fans on. I've researched the internet and all of the solutions available haven't worked for me, so is it time for an RMA or is there anything else I can do?

This seems like a really strange problem. It could be a faulty pcie lane or even faulty psu with the power not being delivered correctly to the card. Or it could be a faulty gpu.

Have you tried installing latest bios for the mobo and resetting bios to defaults?

Haven't tried either of those, I think I have the latest bios tho, not sure. I'll check that. Do you mean resetting the settings to default in the bios, or the bios version? If the latter I can't do that cause there's problems with 1150 CPU's and this mobo (the mobo cranks the voltage up insanely high on the CPU automatically)

I'm not sure about it being a faulty PSU, because I didn't have this problem before with my R9 280X, and surely 650w is more than enough for a Fury??
 
No dodgy processes open in the background? Have you tried rolling back the drivers? remove with DDU and install a driver a step or two back down the line.

I have a really wierd problem where my Gpu's will run 100% but 45% power limit with the newest nvidia drivers. Literally single card performance. Roll back to previous drivers Im getting full performance out of the cards.

Other than that yeah update the motherboards Bios first. That can work wonders.
 
Sound like a hidden bitcoin miner, I had one once when I totally didn't try out gta 5 (I own it on steam now so calm your man boobs) I can't remember what the process was called but most anti virus programs couldn't detect it. There was one that could though which sadly I have also forgot the name of.

Edit: try running rouge killer, think that was the one I used

Did this give you the same issue? All the low fps etc on the first boot?
 
It varied, sometimes it would kick in right away and sometimes it'd wait a bit but i managed to notice my laptop fan was running at 100% all the time and was always red hot and games were incredibly choppy, i went through my processes trying to end the ones without descriptions and luck be it my laptop stopped lagging. did a reboot to see if it was gone and it came back so then did some research on bitcoin miners and found rouge killer to work. doubt it will help but i think the process began with an M.

having said all that it is still possible you have a hardware issue but its good to explore all routes just in case.

RogueKiller didn't pick up anything :( Looks like I might have to do a fresh Windows install
