Hey there buys, grills and all you inbetween!
I have a problem I could really use some help with. I tried posting this earlier but it failed and my patience is low now that I have to rewrite this so please excuse me if now some of the details or if my language fails me. I'll try my beast. Specs can be found at the very bottom.

My theories so far:
- GPU problem
- PSU problem
- Mobo problem
- OS problem

So to get to the problem(s):

- Seemingly at random, my screen won't switch on at startup. As if it isn't receiving a signal. My mouse and keyboard light up as normal but screen is as black as death. This occurs more often than not in chain. I'll press the PC power-button, mouse and keyboard light up, screen is black. Press power-button until dead. Press power button, mouse and keyboard light up, screen is black, rinse and repeat. It goes on like this for any number of times. From not once to "If you don't start this time I will throw you out the fracking window".
When it doen't start as normal I can see the red light from the LED on my motherboard. The light is located as an indicator for the GPU or PCI-slot. When it starts like normal the light is off.

- I recently got a Oculus Rift setup which worked perfectly for about two weeks and then started acting up. Randomly shutting off as if the PC wasn't turned on and then after a while the headset comes back to life again. This also often happens in chain. Off for a few secs. On for a while, spanning from 2 secs to 10 secs. Then it does it again. This happens without any prior signs. After Oculus supports requests the Windows Device manager has all powermanagement-functions disabled. Device manager, at failure, says that the headset and the two sensors aren't working properly. Faulty/missing driver or something (I don't recall). When I removed all unnecessary peripherals the hickups get a lot less frequent. Some minor tracking issues and very few "shut offs".

- My G930 wireless headset will randomly lose signal and then reconnect as if nothing. This either doesn't happen or continuesly on a ca 10 sec interval and then works well again. 10 secs on, 2-5 secs off, 10 secs on, etc. For any number of times. This could be due to the headset itself, it has taken a beating.

- My keyboard and mouse will sometimes randomly shut off. Which makes for fun entertainment in a dark room when they seemingly disappear since they otherwise have a vibrant blue light. They die in unison for 1-3 secs and then comes back to life. This happens in any number of frequency or at any time. (Not just the lights, they get completely killed.)

- Random "Windows peripheral disconnected"-sound. "Connected"-sound is optional and rare.


These are the problems that I can remember right now and all the details I can pull out a.t.m. Please help me diagnose and identify the part(s?) at fault here and what to do to fix it. If you need any more info or details I am happy to provide.

Eternally grateful for your time and assistance!

Philip

Edit: Did run a diagnostics-program but it did not show anything or maybe I don’t know how to use it.

A friend of mine who’s great at computers thinks that my GPU has been running too hot. (86°C) so it might be toast. And then that the main issue has to do with the OS or the motherboard.

Yes, change the psu. Its the cheapest part to change first. If its not the psu, I would say motherboard, with all the controller issue you have. Also try using the integrated graphics on the chip. To see if you are still having the same problems.

Ok that's good to hear. It came with a factory overclock that made it unstable. That's why I'm asking.

CoolerMaster G750M, sorry
