    radeon 5450 driver update black creen startup

    heinflhs

      Hi, I was using a Radeon 5450 in my Dell Optiplex 755 SFF and it worked fine. However, after installing drivers I noticed that sometime when I start up the pc, the monitor screen was black while Windows was starting up (heard the Windows tune).

       

      Sometimes the screen started up and I was able to uese the pc again. Sometimes it did not and I was forced to shut down the pc by holding the start-up button (not good). Sometimes the pc started up correctl, other times it took me 5 - 10 (or more) times to shut it down ans start up again.

       

      Virus scanner, no virusses.

      Malware, no alware.

       

      Yesterday the pc refused to build up the screen completely. Even after maybe 20 times shutting it off and startup again.

       

      This morning I removed the 5450 and the monitor (Syncmaster 930 BF) and took an old Toshiba tekbright 717 and used the original outlet on the pc (not the 5450).

       

      guess what. Screen immediately appearedand I can use the pc again.

       

      Only problem is that when I instell the 5450 again and I try to download nerer drivers and Catalyst, the Syncmaster nor the Toshiba monitors will wordk.

       

      I'm stuck in a loophole, I presume.

       

      With GPU 5450 no screen, without GPU I cannot download other drivers.

       

       

       

      Has anybody experienced similar problems or knows a solution.?

       

       

      Thanx
