progressively worse bsods after working fine for 6 months.  

i selected the repair option and reran verifier with the same settings.
Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.

It was the same misbehaving driver.
Please find a new driver or use alternative hardware.

ok i deleted that software and redid verifer and it gave me a blue screen saying
verifier detected violation
what failed: iocbios2.sys

but no dumpfiles, it stayed on 0%

It's best to debug a dump file.
The reported driver may or may not have caused the crash.

Uninstall and reinstall:

Code:

iocbios2.sys	Intel Extreme Tuning Utility Performance Tuning Driver	http://downloadcenter.intel.com/

how exactly? i went ot the website and there is a file for software and driver. i downloaded the driver one and it said setup failed. can i just delete the folder in C/programfiles86/ intel/ intel extreme tuning utility?

Uninstall the software using control panel.
This should also uninstall its drivers.

After troubleshooting has completed you can reinstall the software if you overclock:
Download Intel(R) Extreme Tuning Utility - Intel(R) XTU

hmm. i uninstalled via control panel and its still in that folder. and i tried verifier again and it said the same thing.

Others had struggled to get a complete uninstallation.
Try Revo uninstaller:

How to completely remove Intel® Extreme Tuning Utility?
If it is still incomplete please open a new thread: How to completely uninstall the software.

Sometimes a work around for drivers is to change abcdefg.sys > abcdefg.sys.old

ok i got it uninstalled and did verifier with those last 5 again, this time it gave me that 75% blue screen and did not make dumps.

Increase the number of customized tests to create more Windows driver verifier BSOD.

If BSOD continue without dump files plan several days of testing in safe mode.
