Good afternoon folks! I've been looking around to find advice or help in regards to the recent and abundant BSoD happening on my system since doing some fairly minor changes to it. Below are my current system specs Microsoft Windows 7 Ultimate x64-bit Version 6.1.7600 Build 7600 Gigabyte GA-790XTA-UD4 AMD Phenom(tm) II X2 550 BE BIOS Version/Date. F2, 03/12/2009 2x2GB Patriot Sector 5 DDR3-1333 CAS 9 (but looks like it's CAS 7 in the bios) in slots 3 and 4 XFX Radeon 5770 1GB with Catalyst 10.3 300GB Hitachi SATA 2 HD 650w Silverstone Zeus Power Supply Prior to running into these errors, I was sporting a 8800GT from EVGA and stock heatsink and fan with the RAM in slots 1 and 2 but now that I have my Noctua NH-12P installed, I had to change the RAM to 3 and 4. Also, I have removed the DVD drive. With this original setup, I never once ran into a BSoD so it seems like something isn't happy somewhere. I have confirmed the RAM is fine by running the Microsoft program upon start up. Anyway, lets get down to the issues. My system has become highly unstable regardless of whether I am playing games, browsing the web, or even opening documents. Typically, I get a BSoD and it will count upwards to create the dump and then reboot but sometimes it won't; however, I do have some examples below. I also get BSoD in regards to Memory_Management and even a Quota_Underflow message. Usually before these happen, the screen will freeze and a glitch/distorted line will go across the top of my screen. When I reboot the system, my keyboard will not work even though the back light is on and it typically throws me through the repair feature where, once it "repairs", I get the Memory_Management BSoD. Sometimes when I load up Windows, the computer will just reboot without a BSoD. Other things I have noticed is the startup time hangs for a couple seconds before posting the Master/Slave IDE ports (mine is on 5) and Firefox will need to shut down. I hope this covered most of the information needed. It's a lot to remember.
