First of all, pc specs:
Intel i5-2500 non-k @ base clocks.
ASUS p8p67 pro motherboard
8gb RAM @1866 xmp profile.
Sapphire TriXX OC r290x 4gb (Hynix) - Tested at base clocks and overclocked with OverDrive & MSI AfterBurner (Seperate attempts, of course) to see if issue with Overdrive not assigning voltage correctly.
Samsung 840 EVO 256gb SSD
Windows 10 x64 Home Edition.
I am currently running completely stable on 15.11.1 drivers, audio drivers disabled, gpu core @ 1100, mem @ 1500 24x7 clocks, custom fan profile, temps never above 75 degrees Celsius, only see those temps when 30+ ambient temperatures.
Typical install process:
Reboot into safe mode
Reboot into normal mode
Reboot as per post installation request.
Everything runs as per normal, drivers are amazing with 10-15% performance increases in just about everything, restarts and shut downs are fine until cold boot. OverDrive functions well in testing though I use MSI AfterBurner to enforce a custom fan profile and voltage increase to support the overclock profile.
Once I cold boot, where one would see the login screen (I don't use a password as only I use this pc, have troubleshooted by setting a password to see if I could force login) the monitor goes to stand-by mode, reporting no input and pc hangs completely.
After doing a soft reset or hard shutdown, the network drivers end up being knocked out and I have to go through the process of resetting the parameters to re-gain network access.
I can enter via safe mode successfully to troubleshoot, after initial cold-boot failure I cannot restart after entering safe mode into normal mode, pc hangs after windows logo every time...
I have tried waiting out the black screen
I have done a complete wipe & re-installation of OS
Post re-installation of OS I have done gpu driver installation prior to & post windows update to see if their was potential conflict
Tested base clocks with/out OverDrive enabled, with/out MSI AfterBurner installed, with/out MSI AfterBurner
Tested overclocking via OverDrive with/out MSI AfterBurner installed
Tested overclocking via MSI AfterBurner
Installation of gpu drivers over the top of pre-existing drivers.
I am at a total loss as to what to do now, would really like to use the new drivers except I do not want to leave my pc running 24x7.
Any ideas would be appreciated and thanks in advance.
