    My machine is causing me such a headache that I'm ready to chuck it in a dumpster. If I only had the $$$ to buy a new pc.....

    I'm using a six-year-old Dell Dimension desktop with a Pentium III processor, 256 RAM (ugh), Windows XP SP2.

    Here's my problem: A few week ago I was able to complete an AVG deep scan but now I can't run AVG Antivirus or Spybot or MS Defender scans without my computer either freezing up entirely or shutting down. I can run AVG in safe mode, and I've been able to complete AVG Anti-Spyware scans and AdAware without any nefarious results reported. I've also successfully run ChkDsk and Disk defrag. No difference.

    On those occasions when my pc abruptly shuts down and restarts, I get an error message that says something about an "unrecoverable hardware error that caused the operating system to stop functioning." My computer also seems to be rather slow at startup and takes an inordinate amount of time for the personal settings to load. Other times it randomly shuts down when I'm using a multimedia program and browsing the internet at the same time. Also, I've received a lot of strange spam in my OE inbox that contains jpg images with stock recommendations and a lot of gibberish in text at the bottom.

    So, is this a hardware issue or a malware issue? I've checked all my device drivers and they seem to be up to date with the exception of three or four devices that are either "not installed or are not required." Hmm.

    Do I have a virus or could my problems be a conflict between AdAware/Spybot/Defender and AVG? Or do you think it's something hardware-related, particularly the power supply? I'm at my wits end here.

    Here's my HJT log:

    This morning i received a "service executable error" after Defender either tried to scan or tried to run an update. Any ideas?

    Try updating Windows Defender, AVG, and re running them - all while in safe mode.

    I'd take things out of start up, and consider getting more RAM (at least 512 mb).

    It doesn't sound malware or virus related to me.

    I've updated Windows Defender and AVG but haven't tried running them in safe mode since doing so.

    How do I take stuff out of startup, and which processes would be best to remove?

    As for my RAM, yeah. I'd definitely like to upgrade to 512 but the cost of SDRAM is so high that I'm undecided as to whether or not it's worth it. About two years ago I purchased two 256 RAM sticks from crucial that worked solo but wouldn't work in tandem. I think I'd have to purchase direct from Dell.

    One more thing: the fan on my power supply has stopped working and I think the one over the heatsink might be inoperable, too. Could this be the cause of the hardware error and random shutdowns/scan freezes?

    Problem solved!

    I bought one of those all-purpose cooling fans and pointed it at the CPU heatsink. It did the trick. Apparently my pc was overheating during those deep scans and crashing.
