Please help. My computer keeps crashing and rebooting. It will just randomly reboot, while playing games (Star Wars TOR, WoW) , working in Lightroom or surfing the web (Firefox). Sometimes it will crash, reboot and immediately reboot again after loading up. Firefox crashes all the time as well. I'll walk into my office and see my computer has crashed and is rebooting on its own, when it was not even being used.
I receive an error message saying, "Your PC ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you." It has listed the following errors: memory management, Kmode exception not handled, PFN list corrupt, page fault in nonpaged area, system service exception, kernel security check failure, driver IRQL not less or equal (usbport.sys), attempted execute of noexecute memory, video memory management internal, dpc watchdog violation, NTFS file system (ntfs.sys), 0xc000021a.
My system is:
Windows 8.1 Pro 64-bit (6.3, Build 9600)
INTEL, Core i7-3930K Six-Core, 3.2 - 3.8GHz TB, LGA2011, 12MB L3 Cache
ASUS, P9X79 PRO, LGA2011, Intel® X79, DDR3-2400
CORSAIR, 32GB (8 x 4GB) Vengeance™ Red PC3-17000 DDR3 2133MHz
EVGA, GeForce® GTX 680 Classified 1111MHz, 4GB GDDR5 6008MHz
Digital Audio (S/PDIF) (Sound Blaster X-Fi Xtreme Audio)
OCZ, 256GB Vertex 4 SSD
WESTERN DIGITAL, 3TB WD Caviar (WD30EZRX), SATA 6 Gb/s
THERMALTAKE, 850W Power Supply
I have reinstalled the OS and all software on the computer and am still having the same problem. I also updated the video drivers. I took my computer to a repair shop. They had it about three weeks and said they could not find anything wrong with it, which I find very hard to believe. I don't know what else to do. It is so frustrating trying to do anything on my computer. I spend more time watching it reboot than being able to use it.
I will very very much appreciate any assistance anyone can provide.
