I nees a PC Time machine for VISTA ..

Since 5/08/2014 My PC has been plagued with gremlins.. First at load up I get e message saying something or another did not load up completely due to "dll" 2ndly I tried to change my "start up options" and it wont let me My Mozilla Firefox page is hijacked by "bing" tried to t remove it to no avail I tried to system restore to an earlier date but my sys. rest. was turned off so I had no reference point. Any way to get back to 2 weeks or a month ago without losing any data??

It is best to do System File Checker for this type of issue:

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.
Let the program run and post back what it says when it's done, if you'd like.
