Me too, but only 1/3. See, I've got 3 computers to maintain (my own workstation w/ i7 CPU, my woman's [really, there is one] personal one w/ i5 CPU, and our entertainment HTPC w/ i3 CPU with a huge monitor). I've upgraded all three from win7 to win10. First my own, about 5mo ago. All is fine, no problems whatsoever. Then I did the HTPC some 2 months ago, and again, no problems. Lastly I did my woman's pc a month ago. All was well a few weeks, and then *wham* nothing works. Pc turns on, slooooowly, there's a desktop, but suddenly u can do nothing. Some features kinda works: u can move post-it stickers around on desktop, but nothing much else. I have tried everything, my whole christmas went trying to fix the pc. There's some corruptions on the C: drive (sfc /scannow, chkdsk C: /f, chkdsk /r), but nothing really mends it.
I have built all the computers myself. They have worked for years, with new components every now and then.
The problematic pc has:
mainboard: Asus P8H67-M
CPU: i5-2500K
memory: 16GB 1333 DDR3
The only "real" difference with the other PCs is that this one has a UEFI Bios.
Then I erased the C: drive and installed the old win7 from an Image. All was well, the PC worked fine with win7. Then I upgraded it to win10 again... And again the same problems. Nothing works.
So, it's not a hard disk problem. Not a drive to motherboard cable/slot problem.
It's win10 problem.
Could it be a UEFI problem? Because the other computers doesn't have UEFI.
Now I'm reinstalling win10, which removes a whole lot of softwares, saving personal data, though. Let's see what happens. Will be back...
Edit:
Okay, done reinstalling. At first all worked fine, for an hour. Fsc /scannow found no faults. Started to install removed programs. Chrome was the first. No problems. Second, Core Temp. Run it, and system tilted, no response, just froze. Then forced restart, and all is fine again. Doing scannow again... Laters...
Edit2:
scannow found nothing, again. Installed RealTemp, which I have on my own computer and working fine with win10. It works on this one too, no problems. Now installing latest Nvidia drivers etc. plus Spotify...
Edit3:
Almost all programs installed, no problems. I think everything happened because of CoreTemp. Do any of you others with the same problems have that on your PC? Or maybe you have some other faulty programs installed that win10 won't have. Opinions?
