Solved ATI Radeon 5770 Update, resulting BSD, code 52 can't verify signature

Hello forum!

I am somewhat lacking in computer skills, any help would be dearly appreciated!

Windows suggested I update my graphics driver, I let AMD autodetect and install but blue screen of death ensued. Now, I have a charming black frame (dead space) around my screen and the colors are f:d up. In Device Manager it reads that the digital signature can't be identified (code 52) for my graphics card.

What the h happened? And why is my computer looking the ugly way it does? How do I fix it? Sorry if I left something out, I am really tired right now.

Also, I can't open the Catalyst Control Center, the hourglass shows up for half a second then disappears and nothing else happens (wtf on top of everything?)

Autosolved! I waited 18 hours to use the computer, then by magic, God's infinite wisdom, sacred herbs, praying etc. everything worked again! This time when I restarted the computer the magical trollettes had been hard at work to make sure yesterday's problems were all just a bad dream.
