P-7811fx Bsod

I have been getting repeated BSOD lately seemingly related to the video drivers.

I have tested the RAM and hard drive. These are not the problem it seems. I have also 'underclocked' the video card. The BSOD's persist.

Any ideas?

The blue screens are related to nvlddmkm.sys and dxgmms1.sys which I understand are Nvidia graphics drivers? Some searching on the net seemed to indicate that the graphics card may be overheating as it ages? Or the power supply is weakening? In either case it was recommened to underclock, which I did, but it doesnt' seem to be working....

Also, I don't recall this frequent a problem before I upgraded to Win 7 64bit... It seems that this is a common issue from searching the net, but no clear solution is presenting itself.

Any advice?

Are you using win 7 drivers, or nvidia? try updating to latest nvidia drivers.

 

I am running the latest Nvidia drivers 266.58

I do not know if it is a common issue, I know that with mine on Win7 x64 it is 100% stable with no bsods. I can't state it is a garentied issue but since you have mentioned the power as a possible issue do you get a BSOD on battery?

 

My laptop is almost always plugged in so I don't really know if it happens on the battery. Definitely when plugged in though!

I thought it had improved, but today I was using it heavily while working on a presentation and it crashed like 8 times. I ran a GPU and CPU temp monitoring program and both seemed fine. Neither spiked to anything alarming.

However as it did seem to get worse when I was using it a lot, I do wonder if it is overheating... I'm really just guessing... Hoping some expert here has a clue or a suggestion on diagnosis. Or perhaps a pointer to some other forum which might be able to help?

Thanks in advance!

well some have attributed a crash to 2d-3d timings but not sure if it is a bsod they get. Since you are just doing a presentation the GPU sould not be heavily utilized.

You might want to try and disable powermizer. This would hopefully lower the 2D-3D timing switch. If this is truly a power supply issue though this may actually increase BSOD's.

Another thing to try is pull the memory and with contact cleaner clean the memory and memory sockets. I have seen this be an issue as well.

I don't know if you have USB or other devices attached, if so pull them and see if the issue continues. Sometimes a driver or even the extra power draw of the other devices can caause an issue.

Yet another issue is the drives. make sure they are not set to go to sleep in power profiles. spin up and spin down along with related power draws and latencies can be an issue.

just throughing some ideas out, not that any specifically will work.............

 

If you are willing to take the risk of flashing new bios you can try my custom one that keeps the gpu at 0.9v and limits it to these clocks: 450/1100/550.
But first I would suggest to make sure its not a drivers issue.
If it won't give you bsod on battery then my bios would probably solve your problem at a cost of 25% performance on the GPU side
