New graphics, black screen, freeze

A few days ago I got my graphics card and power supply in the mail. I put both of them into the computer after removing the old ones. Then I powered my computer on, uninstalled the old NVidia drivers (this new card is ATI Radeon HD 7950, old was GT 430), restarted the computer, installed the new graphics drivers from the site. Now, when I restarted the computer again, I got a black screen after the welcome screen. I powered the computer off by holding the power button, restarted it, and this time it didn't go black. It got to the desktop and the screen had a black bar outline around the edge of the screen, as if the resolution was smaller and not stretched. However, when I checked the resolution it said it was on 1920x1080 which is my native resolution. I was suspicious something was up and went to search the web or a solution but then after browsing for about a minute, the screen locked up and I no longer could move the mouse and nothing responded, and the computer got very quiet.

Attempts: Being that the computer was frozen, I restarted by holding the power. I figured the problem might be the drivers from what I read on my phone and uninstalled the new drivers in the small timeframe before the computer would freeze. I reinstalled and the same things kept happening.

It seems I can run in safe mode and without the drivers installed. Any ideas? Here is my belarc report, let me know if I need to copy more info.

Thanks for any help in advance!

 

Greetings, BigglezMcGee.

To verify: you downloaded and installed the 64-bit ATI driver?

If the correct driver is causing the problem yet the machine starts properly in Safe Mode you might try this: while in Safe Mode run msconfig - under the Startup tab disable everything except the Catalyst driver package. Reboot into Normal Mode to see if your symptoms change. Be advised: if you disable any antivirus startup routines it might be best to disconnect from the internet while testing.

Also, you mentioned replacing the power supply. It would seem that this would be a very strange PSU symptom - but power supplies can be very strange. I'm just sayin'.

 

Hi my friend , in addition to Caliban's suggestion you can use this tool

http://www.majorgeeks.com/files/details/driver_fusion_(driver_sweeper).html

removing completely the old drivers before you can install the new one :wave

 

I tried both of these suggestions and it seems to be working. I've been on the computer for 30 minutes and nothing has happened, which is 30 times better than normal. I don't know if it was the startup change or the driver removal, but it seems that one of them worked. Should I go one by one to see which startup program was causing it?

 

Well, I went back into ms config and made private firewall come up on startup and once I restarted it, it froze again. So, nopf=no problems, pf=problems. Is there any way that pf is somehow blocking my graphics card and causing a freeze up?

 

Tried testing out opening a game up ( no pf on), and I got a screen with white and grey vertical lines across the whole screen, nothing else, and I couldn't do anything. *sigh* Apparently this screen is card is called grey screen of death, which is apparently a problem with many amd cards... I'll look into this further, let me know your thoughts.
