BSOD Problems


Recommended Posts

Not Sure about BSOD's because I've been fortunate to have only seen 3 others since I started putting my own computers together over 10 years now and none of them were recreateable. I have enough knowledge to put my own machines together, when it comes to trouble shooting if I do run into a problem well.. here I am lols..


Here's some the new components for reference


EVGA 132-CK-NF78-A1 LGA 775 NVIDIA nForce 780i SLI ATX Intel Motherboard


CORSAIR Dominator 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model TWIN2X2048-8500C5D Rev 3.1 x 2 sets


Intel Core 2 Quad Q6600 Kentsfield 2.4GHz LGA 775 Quad-Core Processor


EVGA 512-P3-N841-AR GeForce 8800GTS (G92) 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready


Windows Vista home premium 64 bit with all available updates.


I'll post whatever else you need to know if asked.


Here's my problem, I installed all necessary hardware with no problems. Originally only put 2 of the sticks in until bios flash, drivers install and windows updated. Runs flawlessly with 2 sticks of ram in. It read the correct timings for the ram, I had to manually change voltages in bios to the recommended 2.1v. I now go to put all 4 sticks in my machine and it boots up to the windows loading screen and I get the BSOD "IRQL Not Less or Equal" error. Restarts itself and then it automatically changes all my bios setting back to defaults and changes the memory timings to 5-5-5-18 2t running at 800 mhz instead of the 1066 timings I had running with just the 2 sticks installed.


I read there are known problems running over 800 mhz with 4 sticks installed, which is fine with me if I can only run at 800, I just want to be able to run all 4 sticks for the 4 gigs of ram instead of 2. It doesn't matter which slots I use or what combination of the memory I use, it just will not make it through the windows loading screen. I don't have a lot of crap plugged into my computer, usb mouse / keyboard, speakers, ethernet and monitor are all that are plugged into the machine itself. Vidcard is the only thing I have taking up any resources on the board itself. I've tried moving the mouse and keyboard to different usb ports on the mobo and it doesn't seem to matter. Power supply checked out for voltages. System temps all stay cool. The only thing I do notice is when windows is in the loading screen the lights on my mouse will flash and some point, I'm guessing its loading the usb/mouse drivers, but as soon as the mouse lights flash poof there's the BSOD and system reboots. Logitech G5 for reference on that one...


If I pull 2 sticks out runs fine again. Even if I put just one stick of the other set into either of the extra slots I get the same BSOD. I have no clue, it even resets my raid settings in bios to disable the onboard raid when the system reboots.


Any tips, info or a slap in the head because I'm overlooking something obvious let me know. I was up for 27 hour straight trying everything I could to get it to work.. no doing though.. I'm frustrated.. HAHA I love new computers and new technology. My last system made it 7 years and ran everything I threw at it, now with the resource hog of programs out there I had to build a new one to keep up with it all. So help me out if you can.. If not I'll just put my head through the monitor and call it a day .. haha


Thanks in Advance..
