Need some help diagnosing a BSOD

Over the past 17 days, I have had over 25 BSODs. I have tried to figure out on my own what could be causing the crashes, but I'm at my wits end.

Of the 26 BSODs, 23 of them have either been IRQL NOT LESS OR EQUAL or KMODE EXCEPTION NOT HANDLED. From what I have read, this seems to indicate a driver issue, but I've updated all of my drivers and the issue persists.

Using BlueScreenView, it shows that my crashes have also pretty much all been caused by ntoskrnl.exe with the crash address being ntoskrnl.exe+75c00.

I have replaced my motherboard, cpu and gpu. I have also tested my all of ram using memtest86+ and they all came back with no errors. At this point, I feel it is either a driver error, my PSU isn't strong enough for my rig or my HDD is crapping out on me.

My computer's specs are:
CPU - Intel Core i7-3770 Ivy Bridge 3.4GHz (3.9GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I73770

GPU - EVGA 02G-P4-2660-KR GeForce GTX 660 2GB 192-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card

RAM - 2x G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL
(Total of 16GB of RAM)

PSU - COOLER MASTER GX Series RS650-ACAAD3-US 650W ATX12V v2.31 80 PLUS BRONZE Certified Active PFC Power Supply

MOBO - GIGABYTE GA-Z77-DS3H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

HDD - HGST HDS721050CLA362 (0F10381) 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive Bare Drive

Case - COOLER MASTER HAF 922 BLUE RC-922M-KWN2-GP Black ATX Mid Tower Computer Case with Side window


And finally, here are my crashdumps -

If you guys need any more information from me, I am more than happy to oblige.

  1. Use the method from microsoft to see you can solve the problem or not by yourself, because it is hard for us to do this without face to face with that PC.
