Hey thanks for checking out the thread. I'm having some trouble with my Dell xps 400, hopefully someone can help. The issue I'm having is that my monitor, keyboard, and mouse all go dead at random times at the same time. I can hear the fan running and the on light is still green, so I assume there is still power. It doesn't restart nor does it shutdown. I'm at a loss what this could be. Here are my specs Dell XPS/Dimension 400/9150 OS XP professional sp 3 Intel Pentium Dpu 3.00ghz Nivdia geforce 6800 2x 512MB, DDR2, 533M, 64X64, 8, 240, 1RX8 Memory Module 160GB Hard Drive, SATA2 Dell DXP051 Motherboard mouse & keyboard connect through usb The Dell is about 4yrs old. I've checked all the connections and usually dust out the case every cple months. I'm not sure what other information would be helpful. Thanks in advance to any help.
