No. You should copy anything out of those folders that you want to keep. Then use the built-in disk cleanup utility in Windows to get rid of those folders. You'll have to check the appropriate box to do so, while using. I think it will be called Previous Windows Installations.
Type disk cleanup in the start menu then press enter.
Well, everything continued working fine for the rest of the session, I also restarted once or twice to be sure everything was fine. After that I went into one of the VR worlds for awhile... then powered down and went to bed.
Today, I turn the machine on, it starts loading Windows, gets as far as the Starting Windows splash screen, where the colored dots coalesce into the Windows logo... and it hangs (if it helps, it's at the point when there's three little dots set diagonally). And all disk activity stops. What could this mean?
(Turns machine back off, restarts it...)
It recommended Startup Repair, so I let it do that. Seems to be taking awhile.
Okay, after maybe 15 minutes of that, it came back with the recommendation that if I'd added some new device to the computer, please uninstall it and start it again. Should I have let it go back to a previous storage point? Last time I did that, several programs I'd just installed all magically vanished... and I wasn't wanting to go through THAT again.
BTW, this hang-at-startup thing is exactly what it did at this time yesterday.
(Lets machine shut off, starts it again...)
Hmmm, this time it started okay... Will simply leave it running for a little while without doing anything to see if it gets goofy.
Went to boot into safe mode... and it bluescreened. Several times. Both in Safe Mode with Network, and Safe Mode without. (Didn't try it with text-only mode.) Even bluescreened just letting it boot into regular Windows. I let it attempt recovery twice, and it bluescreened on returning from those. One of those recovery attempts, it complained about not being able to access a spot in memory (in ram? on the drive?), or something of the sort. That time it was when I'd decided to let it go to a recovery point. Next time on sending it to recovery, I said no on it going to a recovery point.
I will let it stay off a short while to see if letting it cool helps.
addendum: Dang, no matter what I do, it bluescreens at startup... so I can't get in and retrieve the new minidumps.
Why is it that the machine either seems to work fine for hours, even through multiple reboots, one day, and then bluescreens like nobody's business the next day?
Is this the same MB_WIN7_ATK.ZIP you linked me to earlier? The URL has a slightly different string of numbers in it.
I still don't know how to install it because I don't know which device it goes to, and so can't go to that device and select to update drivers. Do you know what device, or what sort of device, it likely goes to?
Or do I just copy the files in ...\MB_WIN7_ATK\MB WIN7 ATK\64\WIN7 into a particular folder in my system like was done with some of those others?
As for the NVIDIA chipset stuff... I thought I'd already done that earlier...
