New gaming PC seriously underperforming and occasionally crashing

[313411]

I figured I might aswel try asking for help here as I was not getting many responses over on Reddit.

I let my PC get build and tested by a company where I picked the parts myself so I could finally have a good gaming rig. Now when playing games, I have noticed that it doesn't perform as well as I hoped / it should. (Fallout 4: 60FPS or lower, Rainbow Six Siege: Depending on startup either 20FPS or 90FPS, GTA 5: sometimes it starts off at 60+ but dips to 20 / 30 after 15 minutes. That or it starts at about 25FPS) And after a random amount of time while playing a game ranging from 30 minutes to an hour and a half, my game / computer completely freezes up while audio still works for about 5 to 10 seconds, then becomes choppy and then stops. CTRL + ALT + DELETE doesn't work at that point, neither does ALT + F4. Then after a minute or two the game completely shuts off as if nothing happened

Specs:

• 
  i7 8086k (not overclocked)
  16 GB DDR4-3200 RAM
  AORUS Gaming 7 motherboard
  AORUS GeForce GTX 1080 Ti Xtreme Edition 11G
  750 Watt PSU
  Windows 10 Home edition

The highest temperatures I've seen my CPU get was 60°C and for my GPU 61°C.

I have updated and later reinstalled my Nvidia drivers, checked Windows for updates and checked for any BIOS updates but everything is up to date and the issues still persists.

I'm completely stumped as to why my PC is under performing and crashing as much as it is doing and I hope any of you have an answer.

This sounds exceedingly like a hardware issue to me, however you did say you paid someone to build and configure. Have you been on the phone with them? I would expect if you just got it, and it doesn't work right, you're well within you're rights to make them fix it.

I agree. If I bought a system and the graphics card was hitting 75°C at idle, I'd damn sure be blowing up their phone line.

My apologies for the late reply, I have brought the PC back to the store that put it together and told them the things that were wrong with it. I hope they'll fix whatever is wrong with the PC. I'll keep you guys updated as to what they have done and if it fixed it when I get it back. Thank you all for your support so far!

Refer them to this thread if you need to.

I'm a bit late in updating, but here it is.

It appeared that my GPU had a defect, so they replaced it with an RTX 2080 since they didn't have that specific 1080 TI on location.

Thanks for all the help!

Nice. Well, sometimes the universe shines directly on our faces. Hopefully you have no more issues now.

No more performance issues, luckily! Although on shutdown through the Windows menu the light on my microphone (Blue Yeti Blackout) stays on. And very rarely the lights inside of my computer, for example all or some of the lights on my motherboard (and once on my GPU) stayed on. Which only turn off if I cut out the power to the PSU.

Thats often a BIOS setting. Maybe even something fixed in a newer BIOS. I'd update the BIOS.

And possibly the firmware for any/all of those devices as well.
