Hi, hoping I can get some help with Windows 7 Ultimate on a PC I built myself (still have the official install disc), using an Intel chipset mobo with an i7 processor and an SSD for the C drive. I found similar problems by searching the forums, but the fixes in those threads didn’t work or didn’t apply to me.
The version of Windows I have is a Japanese version (32-bit, version 6.1.7601), I first tried posting to Microsoft’s Japanese support forums, but only got one reply and it wasn’t very helpful. So I’ll try and describe/translate my problem as best I can, and will try to Google the English equivalents of any onscreen text.
After a Windows Update, Exact Audio Copy (which I use for my own CDs) would no longer start for some reason. I first tried reinstalling it, deleting its registry entries, and installing older versions, but it still wouldn’t start, so I then tried to use a Restore Point from before the Windows Update.
But Windows froze during the restore process on a blue screen with flower patterns, so after forcing a shutdown, Windows boots but the logon screen is all black with just a mouse pointer. Same thing with the various safe modes, Enable Boot Logging, Enable low-resolution video (640x480), Last Known Good Configuration (advanced), Directory Services Restore Mode, and Debugging Mode. All resulted in a black login screen with movable mouse pointer, so I don’t think it’s a problem with my video card (EVGA GeForce GTX 580). Did not try "Disable automatic restart on system failure" or "Disable Driver Signature Enforcement".
Tried the Recovery Console, but no problems were found in Startup Repair.
System Restore didn't work, there were three points, the first one was to cancel ("torikeshi" in Japanese) the previous Restore operation (presumably the one where my PC froze), the other two were for Critical Updates from a few days ago. The "Cancel" one and the second "Critical Update" one resulted in the error described here: https://support.microsoft.com/en-us/kb/2569601 with error code 0x80070057. I tried applying the hotfix from Microsoft on that page, but I wasn't able to do so with wusa in the DOS prompt in the recovery console, it gave me a library error or something. The other "Critical Update" restore point gave me the rstrui.exe application error "The instruction at 0x732f8f0a referenced memory at 0x00000004. The memory could not be read".
I tried chkdsk /R, but it didn't seem to find any problems (later did it again in HBCD, and it said "correcting errors in the uppercase file").
Unfortunately I stupidly haven't made any system images for this PC, so can't try System Image Recovery.
Windows Memory Diagnostic didn’t seem to find any problems.
When I ran
sfc /SCANNOW /OFFBOOTDIR=c:\ OFFWINDIR=c:\windows
it resulted in "Windows resource protection did not find any integrity violations".
A friend suggested HBCD, so I used that to make a backup image of my C drive, and I ran some HDD tests but didn't find any problems. Also tried resetting my Windows logon password to see if that would let me login, but I'm still getting the black logon screen.
Then I tried a couple virus scans. Avira didn't work in miniXP, ClamWin worked and I was able to update its definitions before the scan but it didn't find anything. Then I tried GMER but it took all night, I don't think it found anything but it closed as soon as I clicked on "Save", then my mouse stopped responding, then the PC froze when I used the keyboard to select Shut Down. The PC still boots, but that was the last thing I tried.
Would greatly appreciate it if I could receive some assistance, but I'm not in any hurry. Thanks in advance.
