Hello, I've recently had quite a few system crashes on my desktop. After I got the first one, they have been rather frequent, 1-5 times per day, usually when watching videos. I have tried reinstalling windows, flashing bios, updating misc drivers, ran CHKDSK on both my os ssd and storage hhd, none has helped so far. System information: OS: Windows 7 Home Premium 64bit Service Pack 1 MB: Asus P8Z77-V PRO (ASUS - Motherboards- ASUS P8Z77-V PRO) Bios version: 1504 CPU: Intel Core i5-3570K Processor @ 3.40GHz Memory: Corsair XMS3 1866MHz Vengeance CL9 (Kit w/2x 4GB XMS3 modules, CL9-9-9-24, 1.5V) PSU: Corsair HX 750W PSU GPU: Ati Radeon HD5870 OS SSD: Corsair SSD Force Series GT 120GB 2.5 Storage HDD: 466GB Hitachi HTS725050A9A364 (SATA) Display: BenQ XL2410T Mouse & KB: Logitech G400 Gaming Mouse, some plain logitech usb keyboard Sound & mic: normal headset using the MB output, plain mic I have no other components connected to the computer. I have attached a zip with hopefully all you'll need, including 6 minidumps. Thank you in advance for all your help!
