IE8 and Explorer are Crashing

I am new to Windows 7 (and this is my first post) but I am having a horrible time with crashing web-pages and windows explorer.

Below are two event logs. Any ideas?

I have reset the add on's and IE8 still crashes.

Thanks. I have done several of these in my attempt to solve these problems. I have used a registry cleaner (Registry Booster), checked for spyware, malware and viruses, tested memory (bought new and tested with it), constantly updated video drivers, have the latest service packs from Windows, and removed Norton Antivirus all to no avail. The only items left are the DEP and printer drivers and I believe that I had these problems before I installed the printer drivers.

I have just looked deeper into my event viewer and found quite a few errors. Take a look, perhaps it will shed some light on my issues.

Sorry I forgot the to answer the question, no, this has been going on since I installed Windows 7. I had no problems previously with Windows NT (yeah, I know but it worked flawlessly). Since I have purchased memory and a new video card to try an solve these issues.
