System Thread Exception Not Handled

Scotspaul · 23 Jun 2014 at 11:06

My PC is unusable right now as I get the BSOD with 'System Thread Exception Not Handled' message shortly after logging in (couple seconds after desktop appears, screen blinks a couple times then BSOD)

It happened a few times a couple weeks ago and I though it may be the memory but memtest reported no issues.

Google suggests it may be display driver related, so i have attempted to boot into safe mode to uninstall driver, but here i have run into a problem. Booting from the windows 8.1 install disk I am trying to enable safe mode from the command prompt as explained in this thread here - http://www.tomshardware.co.uk/faq/id-1653141/fix-system-thread-exception-handled-error-windows.html
When i get into the command line, and change to c: drive, it appears that there is no data on the C drive at all, just says 0 files and 240gb space.
So to me it looks like the PC is intermittently not seeing the data on the C drive? could this be the cause of my issues?

I am intending to A) check all sata leads are firmly attached (I use the ones with the catches though) then B) re-install windows

Anyone got any better ideas? this is driving me nuts now.

Can you boot into safe mode without the windows disk then try to uninstall the drivers.

Not so much as advice but confirmation. I just finished my new build and had the same error popping up every now and then (not as much as you are saying though!). I uninstalled the 14.4 drivers for my 280X with DDUCleaner, installed 14.6 beta and it hasn't happened since.

Hope the gurus of OCUK can help!

OK, just to update I have managed to boot into safe mode (not too hard - thanks Google) and uninstall the old gfx card drivers.
Interestingly I was on the 14.6 drivers already.
I used driver fusion to flush the old files out then re-installed 14.6 again.
All seems fine now - no BSOD - yet.
Interestingly, windows reports driver version 14.2 from the control panel/device manager window, yet MSI Afterburner shows 14.6 installed. Strange

I'm still convinced there's something else wrong with my pc. Time will tell I guess. My PC did get pretty toastie on Saturday night, both 290's were hitting mid 80's, so maybe that has caused my issues?
I have had my 4770k overclock backed off to 4.3 for a while now but if the system stays stable i'll whack it back up to 4.5 and see how it goes.

GPUs getting to 80C won't have caused any issues to the rest of the PC (or themselves) - you need temps well in excess of 105C before thats even remotely likely.
