I was on Windows 7 - 64bit, and got the free upgrade to Windows 10 PRO at the same time as updating my graphics card (7870 to R9 390).
But at random intervals, without any prompting, the screen will just go black and the computer completely unresponsive. It varies in time between crashes, from a few hours, to up to 4 in an hour. I have to hard reset after every one.
I tried to use the windows reset function but got stuck on an inaccessible_boot_device error so I decided to do a clean install with a bootable DVD, but the issue returned the same day.
I can't spot anything in the event viewer that happens just before the crashes and it can crash when I'm not actively using the computer.
Ive run error checking on my SSD, and that came out fine. I have all of the latest GPU and chipset drivers. I ran memtest for 8 hours with no errors. The Crucial SMART tools report my SSD is in good health.
SFC /scannow gives:
"Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not
supported in offline servicing scenarios."
Running DISM.exe scanhealth gives:
"The component store is repairable.
The operation completed successfully."
Then Restorehealth gives:
The source files could not be found.
Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see http://go.microsoft.com/fwlink/?LinkId=243077"
Ive found some dump files in the LiveKernelReports/WATCHDOG folder that seem to occur every few blackscreen crashes, but not all (included in perfmon.zip). They point to the Atikmpag.sys driver, but the AMD video drivers were installed on a fresh system, so it shouldnt have any issues with previous installs.
Im just completely lost as to what to do next because unlike bluescreens, it doesnt leave any sort of dump or error other than "the previous shutdown was unexpected".
Any help at all would be really really appreciated.
