Inactive Completely Random DEP crashing Explorer.exe

[Inactive] Completely Random DEP crashing Explorer.exe

Hi there. I've just recently re-installed Windows XP 32 on my PC about 3 months back. Since then, I've been up to date with all drivers and windows updates as well. Recently, about 4 days ago, I began to get DEP crashes that literally crashed whatever process I was running at the time. So I experimented with DEP for a while until it stopped i.e. Turning on DEP for all programs and services excluding those that I select manually. It stopped for awhile, but now I'm getting explorer.exe crashes intermittently while some programs are running without any prompt at all. Of course explorer.exe starts back up as soon as it crashes, but its starting to get obnoxious. I've already done several antivirus/malware scans with Avast, AVG, and Spybot Search & Destroy. Nothing is turning up so I decided the best thing to do was submit a Hijack this report to see if their is something I'm missing. I've never really read a log so any help interpreting what my issue might be is frankly VERY WELCOME at this point. I've never had this issue before, and I'm the kind of person that freaks out and runs memtest overnight if some problem keeps flaring up randomly. Well once again I appreciate any and all help given. Thanks in advance.
