I have reformatted my PC. Installed from scratch. Installed no software. Works with win 8. But once I try upgrading to 8.1 proper, it fails. I tried all ways, update drivers then upgrade. I have stripped the PC to barebones with only graphics card and a normal HDD. Get this error too. Seems like I am stuck with win 8. :(
it is frustrating. And the PC is only two years old. Works perfectly fine. Throwing it out just doesn't cut it for me.
