Covered with crap. With crap on the top. Look on the bright side. I find him very entertaining. He told me that my system was incapable of running with a single DIMM. I double and triple-checked to make sure: yep. I have my single 1 GB Samsung DIMM in there. I had to check again just to make sure that chance hadn't taken advantage of me and caused one to spontaneously form and seat itself properly. Plus, if it had, I could probably make a lucrative business exploiting that. I still haven't ruled out the possibility that such a phenomenon happens and the DIMM disappears when I take off the side panel to my case. I need to get ram gremlins to sit in there with a camera just-in-case. Maybe I'll go check pricewatch for some ram gremlins... -Matt
