This is one of four things, which can be checked in order: 1) memory 2) video card/memory 3) power supply 4) main logic board Before you do anything else, take the thing apart (use an ESD wrist strap) and reseat all of your connectors. Actually unplug the DIMMS (memory modules) and replug them. Unplug the power supply connectors and reseat them. Gently unplug all connectors on the main board and reseat them. Unplug your cards (particularly your video card if its not on-board) and reseat them. Reboot and see what happens. Is your video card an nVidia chip set? If so, try another one... voodoo, etc. I keep an 250 watt power supply in the closet for this purpose... basicly, swap out the power supply with a known good one and see if the problem goes away. Bad supplies are notorious for causing this type of failure. If the problem does not go away with another power supply and the video is on-board, then your main logic board is probably bad. Intermittent problems are almost always hardware related... however, some flaky problems can be due to drivers also... have you upgraded any of your systems drivers that might correlate to the hardware problem you are experiencing? Oh, one more thing... instead of rebooting... when your screen locks up have you tried bringing up a black screen console with ctrl+alt+F1 ? -- Kind regards, M Harris <><
