Major NVIDIA GeForce: Graphics Become Distorted

I just now decided to join but I've been looking around the forums for a while now as a guest. Recently I was referred to the website laptopvideo2go.com by these forums. I went there and because I had the old factory installed version 98.15 driver for my NVIDIA GeForce Go 6150, I decided to download one of the newer ones. By the way, I have a HP Pavillion dv6000 laptop. The driver that I chose was 7.15.0011.7770. It installed correctly and everything worked fine except for the fact that whenever I logged on, the screen would flash black and the graphics would become distorted and blurry and my desktop icons would look really magnified. But then, a few seconds later, the black screen would flash again and the graphics would go back to normal and everything would Today, however, the graphics did not revert back to normal. Everything stayed really big and fuzzy. I thought that since the driver that I downloaded from laptopvideo2go.com was not digitally signed, or whatever, that it was the problem. So, I went to the HP website and proceeded to download the original NVIDA update (98.15), that I had previously, for my driver.

It installed like normal until it got halfway in the installation loading bar. Then, my computer suddenly restarted itself and said that Windows did not start correctly and gave me the option to run some repair thing. I did, and it couldn't fix anything. So, I restarted again and got the same thing and went into safe mode and uninstalled my driver. Then, I updated the driver with the same 98.15 update and it worked and told me that I needed to restart. So I did and I got the "Windows did not start correctly" message again and I went into safe mode. The driver had not installed and everything was still big and fuzzy. However, the driver was still deleted. So, I restarted again, got the same message, and went into "Last known good configuration" mode, which I am in now. And, of course, the display is still really big and fuzzy. if you select the start normally option instead of the repair option, it will proceed to load with the Windows loading bar but will do that automatic restart thing before it gets to the Windows Vista logo every time. So, it's like a never-ending loop of restarts. I did some research online and I found out nothing, so I guess that my problem is unique. I'd really like to have my computer's original crystal-clear graphics back, but right now the priority is actually getting it to log on.
