Dell :: Computer Freezing After Startup, Driver Problems?

Not sure if this is the right place to post this, but I've been having some issues with my E1705 recently. I was just using it for the normal internet browsing/ iTunes playing sort of thing the other day when it up and froze on me. This would happen occasionally, like once a month or so and I generally don't think much of it. However when I rebooted my computer it froze again after about 3-5 minutes after logging onto my user. I run XP still and was able to get enough time in to do a system restore to a few weeks back, but this didn't manage to fix the problem. I can boot it up and run it in Safe Mode for hours with no problems whatsoever. I ran AVG and Windows Defender and neither of them caught anything, and I'm leaning towards it not being a virus, mainly because I hadn't ventured out onto any new or foreign websites within a couple of days of this happening - its not like I was looking at some new site, I was checking my Gmail, Facebook, stocks, etc.

I was wondering if it could possibly be drivers that are causing the problem? I'm not really technically inclined enough to know where or how to look into this. I've exhausted my limited knowledge of easy fixes. I would really rather not clear my HDD and start new, that would be a severe last case scenarior. Just wondering if any folks on here might have some suggestions for me as to diagnose or fix this.
