Not Geek Enough

I am having severe computer problems which is the reason for the lack of posts. I will be back and running as soon as humanly possible. I am not sure just how I am going to do that yet, but I'm working on it. In the meantime, those of you who may have super powers with computers may have an answer for me. Here is the summed up issue: bad_pool_caller blue screen with Windows XP. Won't boot in safe mode, debugging mode, or last known configuration. Argh! I've even tried reinstalling the OS without success. I may have to bite the bullet and call the Geek Squad. Anyway, here's hoping my computer gets fixed soon. Thanks for your patience.
