Just returned to my pc while I was out and found it had restarted.
Now when I boot it up I get the following errors:
Windows Logon LogonUI.exe
c:\windows\system32\rtrutils.dll and
c:\windows\system32\POWRPROF.dll
saying that these files are damaged or corrupt
once I click OK to these I get a black screen with white mouse pointer
system was working fine with all updates / scans etc
System: Vista Business, 2gb DDR2, 320 GB SATA2 HDD
I have tried running a last known good, safe mode, chkdsk and a startup repair but no avail
any ideas what causes this and how to fix it?
I'm booting of my UBCD4WIN USB drive just now
regards
