I work for an ISP and we do pc repair in office as well but im starting to have a problem with my office pc. We arent a big company just a few employees so we usually take care of the pcs ourselves. Currently my pc has been Freezing up and the mouse light goes off as well as the keyboard #lock light. Here are the specs Win XP Pro 32bit P4 2.66Ghz Northwood Socket 478 Gigabyte 8IE533 Motherboard 1GB ram (512 stick, 2x 256 sticks of ddr) FX series graphics card I can be surfing the web, using microsoft access or anything else when it happens. Id really like to figure this out as working with a customer on the phone and you pc freezing is starting to get really annoying. If you need anymore info just ask and ill provide. Thanks for any help.
