Vista SP 1 froze on 2 out of 3 - is it corrupt?

Sometimes it happens. But I've yet to have issues when I see it. Just go ahead and install SP2.

Your POST is confusing..rebuilding your PC means mechanically taking it apart and putting it back together..

===

If what you did was to Re-install the OS..then that is also called a Clean Re-Install of the OS..

===

If your getting a Installation Screen--for Microsft Updates..declaring ...xxx-%...it should also say..Don't Turn OFF your PC..<<--which means-->>Don't turn Off the PC..

===

Vista is a SP-1 Edition..

How-ever..there is a SP-2 Update..once you've fully install the SP-1(version)..

You move to the SP-2---Update---which is a good size file..about 45-minutes..even at DSL..//

===

Doing a Clean Re-Install..of the OS..also means adding in your Drivers..as soon as your at your Desktop(OS..re-intall)Completed..next is Drivers..and you must install the Chipset Driver(first)..called the INF-File..

===

The rest of the Driver's don't seem to have a special order..

But once the Chipset INF-File is installed..it can be re-installed..so don't mess up on that operation..

===

If you now have your OS...fully installed w/Drivers..

Its time to add your MODEM..so you can use Microsoft Update..

I add my ISP and DSL Modem...and then I register my Product w/Microsoft..

..then I go to UPDATE..usually--I shut OFF..Auto-Update..the computer should handle all of that..its best too stand-by so as::to READ any important messages during the Update Process..//[end]
