Hello,


I have made my new pc and started gaming at first the system was perfect but now after about 2 weeks usage my pc is starting to lag while gaming, the fps drops for certain games like Elden Ring and GTAV, as of now I have been playing these games more recently. the fps drops to 0-1fps and the screen freezes ever so often sometimes constant.


When looking into task manager I can see that my gpu usage drops from 60-80% to 3-10%, as if the pc is on idle screen. the cpu also drops usage but by like 5% I have updated all drivers and softwares, as well as bios. unplugged re plugged in gpu, made sure the gpu is mounted and all cable are connected properly. I have also reinstalled windows and reinstalled all drivers. The weird part is while doing stress tests there were no issue, I also did benchmarks on 3dmark as well as GTA's benchmarks still no issue or throttles. So I am out of ideas.

The issue did occur after installing a cpu contact, but I added a sufficent amount of thermal paste and the thermals for the cpu and gpu are fine. I also downclocked my cpu and gpu to its normal state and this still occurs.


Processor: Intel(R) Core(TM) i7-14700K 3.40 GHz (OverClocked w/ MSI bios)

CPU Cooler: NZXT Kraken Elite

RAM: Corsair Vengeance LPX Black 64GB (2x32GB) 3600MHz DDR4 (OC to 3800mhz)

Motherboard: MSI PRO B760-P DDR4 II

GPU: GIGABYTE - RTX 4090 24 GB GAMING OC Edition

PSU: BE QUIET! Pure Power 12 M 1000w

Monitor 1: Gigabyte M27Q X 27 Inch SS IPS QHD (2560 x 1440) 240Hz

Monitor 2: LG UltraGear 24GL600F 24" Full HD 144Hz

Windows 11 Pro

(the video looks weird coz I had hdr on but i have turned that off, this also occured regardless with hdr on or off)

what do you consider "fine"?

what are idle and maxed usage temps for both?
So for idle temps, cpu idle is 35-40, cpu max is about 65-75 (not on pc atm so i dont know cpu temps directly).

gpu idle is 25-30 gpu max is 60-65.

I used intel burner for cpu stress test.

When doing gpu stress test i used furmark the “hot spot” is 72 I dont know if thats the gpu’s max temp. (the maxes are from separate stress tests).
