Could Old Intel Graphics Driver Cause IE9 To Crash

I've been having problems updating my Intel Graphics Media Accelerator driver, 8.15.10.2119. It is the version that prevents Win 7 SP1 from showing up in WU. I read a thread about this very issue from 2011, but the link provided to go to Intel to get the latest driver leads to nowhere. I cannot find a place to go to update the driver. I manually downloaded SP1 and installed it and it is working fine. My question is: do I still need to update the driver, and if so, where do I get it from? Neither HP nor Intel is any help here. And would this driver cause IE9 to crash? The computer came with IE8 on it, but I installed IE9 in Nov. 2011. Shortly after, I was getting a message like "Internet Explorer has stopped working". I uninstalled IE9 and went back to IE8, but I had the same problem there as well. IE8 worked fine until I upgraded to IE9. Then I uninstalled IE8 and changed to IE9, where I still have problems. I have contacted MS Support about this, and one option given was to reformat the hard drive, which I really don't want to do. They were concerned about the fact that SP1 was not offered and hinted that the computer would be more vulnerable to problems without it installed. My firewall and anti-virus have turned up nothing. I use Trend Micro Titanium Internet Security.
