From time to time some friends call with mysterious problems…. they describe it like “PC is broken”, “it does nothing”…
Solution: the motherboard wiring to the front panel was wrong -.-
Now the system works fine, one little stumbling block thru set bios-defaults, AHCI configuration was gone. Go to BIOS – storage configuration – change IDE to AHCI otherwise Windows won’t boot.
This was the fast part, now the time consuming one….
Installed System: Windows 7 32bit Home
Windows 7 without Service Pack 1 (release date 16. 02.2011) and I thought it is time to solve the problem its summer 2016!
First I tried to install the downloaded SP 1 which ends in the same error like from Windows Update –> ERROR_TRANSACTIONAL_CONFLICT(0x80071a90)
thru this error and a little search I found this Microsoft Article how to perform a clean boot in Windows.
This solves the conflict and reveals a new error..
So once again SP1 –> ERROR_NOT_FOUND 0x80070490
sfc /scannow –> did not find any problem.
System Update Readiness Tool for Windows 7 –> did not find any problem.
before I give up the solution is found here.
Locate the File:
c:\Windows\inf\setupapi.dev.log
