Black Screen and Sound Looping when Gaming

[AEM]

Ok, so this issue has been persistent for the past month or so and I've flipped the Internet inside out trying to find a solution but with no luck. The sum of the issue is that after between 5-15 minutes of gameplay, my PC will blackout and sound loop and keep doing it until a hard boot. I've managed to mash my windows key and mouse and got out of it in time to see a "Nvidia Display Driver has stopped working" (but it doesn't say "and it recovered" message). I get no BSOD or auto-restart so no dump files to give out. If there is a dump file for Nvidia drivers crashing I don't know the location (if it exists), so if somebody tells where it is I'll upload it. The weird thing is it usually happens to games like TF2 and CS:GO.

I don't think it's related to my PSU since this hasn't happened in the past and my OC (only +80 mhz on base clock) hasn't affected any games in past either.

I'll go ahead and list the things I've tried and have failed, the measurements, and my PC specs.

PC Specs:

MS Windows 7 Professional 64 bit - Intel i7 4770 @ 3.4 ghz (stock) - Dell
0KWVT8 Motherboard (BIOS A06) - 24 Gb DDR3 RAM (2x8 Gb and 2x4 Gb) @ 1600 Mhz -
2x1 Tb Seagate HDD @ 7200 RPM - Nvidia GeForce GTX 660 Ti (OC'ed) (Reference Card) -
Corsair Cx600 PSU

Things I've tried so far:

• 
  ■ De-dust my entire PC (I do it on a monthly basis)
  ■ Do a clean installation of Nvidia drivers (Uninstall in Safe Mode, Drive Sweeper,...)
  ■ Run Malwarebytes, Roguekiller, etc. to check for any Bitmining malware hogging my cycles
  ■ Try running game on original clocks

GPU benchmarks during gaming

• 
  ■ Temperature: Around 75C
  ■ GPU Load: Around 80-90% and jumps down to 0-10% every 30 seconds to 1 minute

Thank you to everybody in advance for taking the time to read and respond and hopefully there is a solution.

[strike]EDIT: I forgot to mention the drivers are up to date on 335.23, but I found some have had issues with it. Is it possible that the latest driver is the cause of it?

Update: It seems even after clean uninstalling and rolling back to 332.21 still causes the crash.
