Hello Mafi, welcome to SevenForums!

I have taken a look at your dumps, a lot of the dumps are similar, but you have different errors as well in general. You have one "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M" bugchecks, two "KERNEL_MODE_EXCEPTION_NOT_HANDLED_M" bugchecks and one "REFERENCE_BY_POINTER" bugcheck.

Interestingly enough, 3 out of the 4 dumps provided show that dxgmms1.sys as the faulting module / image name. dxgmms1.sys is a Microsoft related file that has to do with DirectX. It can be graphics related (software or hardware), memory, power supply, etc. Many things can cause this specific 8E bugchecks.

The first thing I recommend you do is uninstall your current graphics card drivers, and then update your nVidia drivers to the latest version.


If updating your drivers does not solve the problem, we'll move on to hardware tests:

Run Memtest (I recommend for at least 6-8 passes).

Download and run SeaTools to test for Hard Drive issues.

Old driver(s) that need updating:

3xHybrid.sys - 3xHybrid Fri Apr 20 01:34:48 2007 (ASUS Hybrid TV Tuner by Philips Semiconductors GmbH (may have ATI chipset) - SAA713x PCI TV Card). Update here.

Thanks for the reply.
I uninstalled the drivers, then installed the newest ones. We'll wait and see if I get bsod still.

I searched a bit, and saw that when you update your drivers you have to uninstall the old ones first.
Could this be the problem? Cause i might have installed the newest drivers in the past, without uninstalling the old ones.

I would always recommend uninstalling old video card drivers before installing new ones, yes.

BSOD error 0x0000007e Help!
My desktop randomly blue screens at certain times like when I boot up, or 30 minutes from then. I booted into safe mode and the problem doesn't happen so it might not be any hardware. I don't have any restore points I can use to go back and I've already checked my PC for viruses, what do I do?
