But why did you do that?
Also, where is the power supply noted as well as did you take this up with the machine's maker?
Any seasoned tech will nod as you declare such and then promptly do the test. (cover off, point a fan at it.)
Heck, you/re a gamer expect problems. Not to pick on you but you have an OC version of the video card. Also, if you check your video ram use, see if any is also provided by system ram. Your video card will be noted as "deciated ram" and any other is system supplied. On top of this, you're in a SSD world where I'm sure drivers reside. Excluding even that, you expected speed and probably have the highest setting, did you try to trottle back? All, this boils down, sooner or later yopu find the weakest link. often enough that maybe the PSU, but yours is probably OK. BUT! there is no heat sensor in that PSU, the power output varies on demand and if it reaches into the 80% range too often you've exceed it's limits even if rated, that' suppose to be now and then range, qualuity does matter. Heat issues, simply remove side cover and place household fan and check results. Also, understand heat stress will degrade devices/items and once stressed, it won't fix itself, it' prone to repeat until replaced or allowed to work well within and below its limits.
Read these forums here and elsewhere on all those gamer PCs that poop-out. Whatever the cause, gamers tend to stress and prolonged play does that. Thus, attention to detail and cooling is a must. Further, quality makes a difference all its own and will offer best results.
You may find a previous driver in downloaded programs or can search for one in device manager.
You may have a restore point for it as well see "help and support" for restore point instructions.
Even new drivers can be faulty. You maybe getting a new driver for it soon.
