Opera Issues on Win7 PC.

I'm having issue after issue with this custom built PC. I left for class after setting my computer up to defrag and upon returning, my system went to sleep as it usually does. When I signed back into my account, something happened. I remember something like a window for Opera opening up to update or some such (I don't remember exactly) and then Opera starting as usual. Once it did, the screen did a jolt and turned blue giving me a 0x03B error.

Upon rebooting, Opera refused to open. It opens with a completely black screen for about 1 second and immediately closes. It adamantly refuses to open or do anything further and opens a second window that is also pitch black, I can't see any words, only 3 large selection dots with no description and it claims it has to "restart." This puts it in a loop. It also has been noticed when I tried to uninstall via Control Panel, it will not do anything, it does the "loading" symbol on my cursor and stops, doing nothing. No other windows pop up, no commands, nothing more. Anything that does show up in the windows is black and I am unable to see anything.

I installed a newer version of Opera deciding that may fix the issue and overwrite the other folder and ended up installing it in the wrong folder (cause I'm a genius) and starting it, once again, it crashed and gave me the same error. Upon rebooting, it started normally and I've had no issues. However, uninstalling the previous version isn't proving effective, and using System Restore has given me no change in this either.

How am I to rid myself of the old version and install a newer version without the constant BSOD's? I'm in the middle of running some hardware tests on my comp to rule out those problems, but I see no reason why Opera is causing system crashes like it is.

NOTE: System Restore also had the fun backlash of deleting my minidump files so I no longer contain the memory dumps for the BSOD's.

use a program called your uninstaller
