Bsod ntoskrnl+748c0

Loaded BIOS in Safe mode!!!!

Update: seems to be taking a lot of time - 5 minutes - updating the BIOS?!?!

Update2: quit bios update in safe mode. Rebooted fine.

I'm begining to think youre correct. I swapped out the C: drive with another drive. The second drive is a clone of C: drive; the cloning was done months before these issues started. I got the BSOD. So I've removed DIMM #4 and have swapped back to the current C: drive. Whem'if it fails I'll closely inspect the mb for issues.

Heh, glad that i could help.

I thank you and all folks who are helping. I have a feeling the issue is heat-related as the computer will run fine for 10 hours or so after being shut off for several hours. Also, I'm running a Scythe cooler on the processor. It partially overhangs the memory (see attached) and may impede cooling of the DIMMs. I pulled DIMM #4, the easiest DIMM to reach. Btw, I'm running BOINC (Berkeley Open Infrastructure for Network Computing), doing cancer research. This runs (when it runs!) at full bore - 100% on all 4 cores. I also have a 92mm side exhaust fan; it's set up to run at max rpms. Same for the bottom rear fan. CPU temps remain below 45* C., while Northbridge temps stay below 50* C.

Update: I run "CCleaner" on a daily basis. In the last few weeks it seems to run verrrrry slooooooowly. I suspended BOINC to run CCleaner. It took over 20 seconds to compete its run, and only deleted 17MB of trash. Memory issue? Why no alert? ARGH!

Hmm, can you post Speecy screenshots of the temps? This also be a failing HDD so run SeaTools.

Thank you for researching about cancer. Someday we will cure cancer and less people will die of that horrible disease.

It's not the HDD as I temporarily installed another system disk that I mirrored to before the BSODs showed up. It ran for hours and then BSOD'd with the same thing. Also, after each BSOD I've run as admin SFC. Never an issue.

I've attached a screenshot of the Cupid HW Monitor (and more).

Thanks,
Mark

Your GPU is overheating a little. Can you borrow a friends GPU?

I think my mb has builtin vid. I saw it run a lot hotter during the Ferman test. I think it's ok.

So far so good with DIMM 4 empty.

You're welcome on the research. I built a very high performance single core box around an AMD Athlon FX57 for cancer research hosted at Oxford University. My dad died of lung cancer in 2002. A friend (super smart), with whom I went to grade school and high school received his phd in bio/chem from Oxford, was athe wake and funeral. He works are the National Cancer Institute.. His adviser at oxford was Dr. Graham Richards, one of the pioneers in using computers to perform chemical research. Dr. Richards' theory was that cancer generates and needs one of 12 proteins. If we can interfere with those proteins we can stop cancer. I ran that program for 4 years on my home and my work computers.

Wow, interesting. Sorry about your dad though. May he rest in peace.
Well of course it should run hotter in Furmark as it's a stress test on the GPU. Still the GPU is pretty hot for being idle. But so far so good, hope there won't be anymore crashes.
