Computer doesn't sometimes boot until I replug computer, Fps drops in games.

[mctana]

Hey, my pc has been acting weird for like last 6 months.

- Sometimes when I boot there is no display, or there is display but it gets stuck, until I unplug and plug the computer.
- Sometimes fps drops to 10-20 for 10-60 seconds. Sometimes, but rarely this stays until I restart the computer.
- Sometimes screen stutters and flickers even when I'm only watching videos.
-Sometimes boots up with wrong resolution
All of these seem to happen so randomly. I've had some other symptoms which I cant remember right now, I'll add them later if they come to mind.
My temps are fine, ive done memtest, updated drivers.
What i've noticed when this fps drops for a 10-60seconds my Power% goes from ~50% to ~10%.


My specs:
Gtx 760
I5-4670k 3.40
8GB RAM
XFW 450W
Asrock Z87 extreme3
WD caviar blue 1tb

Anybody?`

sounds like a gpu breaking down. Try to run real bench/cinebench with gpu related test like opengl and report back. FPS usually will not be impacted by psu, so I will put PSU next one on the list.

Do you generally unplug your PC when it gets stuck or won't respond? That's not healthy.
How old is your PC? Especially your PSU.
Do you have a good antivirus? Or try using Malwarebytes to do a full scan.

No, I always close it with pressing the button down for 5 seconds if it gets stuck. I meant that when there is no display on startup I have to unplug and plug the computer after closing, for it to finally display something. My computer is ~3 ½ years old. I have avast antivirus, and I've done malwarebytes scan few times and it hasnt found anything. Can't do avast full scan tho, it gets stuck at 0% dont know why.

Because Avast is bad. Your PSU might be dying or the GPU. Try some benchmarks like cinebench or 3DMark and see if it can run without artifacts.
Also monitor temps and usage with MSI afterburner on CPU and GPU.

I did the cinebench OpenGL and CPU test. In OpenGL I got 110 fps and my GPU temp went from 40C to 50C GPU usage was 30-60% CPU usage was 30-40%. In the CPU test my CPU temperature went up to 65C and CPU usage was 100%.

no crash? try to borrow a PSU and test again. If issue is gone, get a new psu. Check if PSU is still under warranty.

Okay, ill try to find someone to borrow from. I might aswell add some more details now that came to mind. Earlier today I booted up the computer without problems, but when I started games, straight from the start I had 20fps with like 0,5 sec delay with mouse movements etc. Then I just restarted the computer and all games worked without any problems. Is it possible that my GPU boots up wrong sometimes? I don't know much about these things.

Before borrowing a PSU, let's reinstall OS and update BIOS. If those two do not help, hardware is the problem.
