Hello there,
Recently, I've had some performance issues with my RX 6750 XT, thus i decided to update to the latest Adrenaline Software. After a successful download, it told me to restart. The reboot however failed, and upon restarting i got a greyscreen. After about 10 minutes waiting i got my Board's BIOS access on screen (option to F2 etc), and after waiting another 10 minutes it went into troubleshooting mode, yielding no results however.
I did the reboot 3 times to go into safe boot thing, and sequentially tried all my options, failing to boot with a lot of the options. Resetting to before the last functional update (Windows 10 did an update a day earlier, though successful) finally did it, and after waiting 10 more minutes i finally got my Login screen. Functionality however was down after this. Several Apps wouldnt start, or failed to launch all their funtions. Both my 7700s internal GPU and my 6750s GPU drivers are installed, up to date and seem to be working though.
I then tried to reboot it again, but received the very same greyscreen from earlier, having to do the triple boot thing again. This time however, i just let it work through its troubleshooting menu, and after 40 minutes i got my login screen back. Functionality still seems to be off though, with a lot of apps failing to start within their usual timeframes, and a lot of them still having graphics problems, for example, Prusaslicer not displaying my 3D models, CAD software needing 5 minutes to start, when its usually like 5 seconds etc...
Unfortunately I'm a complete novice in PC diagnostics, and dont know how to give any more detailed information for now...
I hope someone can help me with this
