PC has GPU usage drops

[mike5703]

My PC has GPU usage drops. i usually play Rainbow Six Siege and according to the graphics menu i use about 1700 MBs of Vram, and the game itself freezes sometimes and i get kicked to the menu after 20 plus seconds.At times i can go a whole 3 hour session and no issues, and sometimes it happens 2-3 times in an hour. just recently it started to go form just freezing outright to having big drops then a few seconds later jumps back up, and causing a lot of stuttering.I checked the msi afterburner graph for GPU usage and have big dips from 60-75 percent usage to 0 and the temp never passes 74 Celsius. the PC i own is a prebuilt HP Omen 870-224. the pc was bought at the beginning of march so its barely around 2 months old. The PSU is rated at 500 watts. I have updated the drivers and did a clean install also.

Specs:
I-5 7400
GTX 1060 3GB
8 gb ram
1 tb HDD

Rainbow Six Siege is a very unoptimized game, there have been numerous posts on this problem and from what I can see there is no solution that works 100% of the time.
I would recommend you to try some of the standard troubleshooting steps like:
1. Reinstall your drivers for both GPU and CPU, make sure you get the newest drivers from your manufactures website.
2. Reinstall the game, game files could be corrupt.
3. Reseat GPU if possible.
4. Set fan speed to 100% in MSI afterburner, just to make sure the issue isn't temperature related.
