    Ok I gotta challange for you guyz! Symptoms: Computer Restarts Randomly when im running several programs or one. What its Not: Memory, CPU, CPU Fan, Hard drive, OS, Optical Drive. Might be: Power Supply, Motherboard. I dont think its the Power Supply tho. I've ran Hardware Tests and everything Passed with flying colors, Ram passed but still replaced because sometimes doesnt show up in tests, i dropped the CPU temp to the lowest it can go, replaced the CPU, CPU Fan, RAM, Reinstalled XP 3x. I'm thinking its the mobo but all tests checkout.... So came to you for some advice! Any opinions will help! Thanx

    What power supply do you use? It could be providing intermittent power to certain devices.

    Hmm, not exactly a high quality unit. I'd suggest replacing it.

    Please post a spec list of your hardware.

    Are you installing the drivers from the original driver disc or manufactures website for the hardware or are u using an nlite xp disc. as it could be a driver issue.

    It may be worth turning the automatic restart off so if it does crash it may give you some info on the cause. (Control Panel, system, advanced tab, startup and recovery - settings)

    When windows reload does it come up with a box saying windows has recovered from a serious problem. If so what BCCode do you get.

    Oh and the computer does not shutdown, it just restarts as if you pushed the restart button. Got Drivers from MSI. Even tried to Update BIOS.

    OK, so we can write that one off (but I'd still recommend you change the power supply anyway). If you've tested everything else it might be the motherboard. Does the PC have a dedicated graphics card?

    Nope, all onboard. just unplugged one of the HDD's if that fails will try the other. Im hoping its not the MOBO dont feel like taking everything apart and shipping it off, waiting for them to test it and send me a new one!

    well the only reason i bought this power supply is the way it looks, it matches my case... take a look. The other Logisys PS i have came with another case i got. and by the way since i unplugged the other HDD so far so good, been about an hour and a half. so lets keep our fingers crossed, i keep you posted.

    That's not a good reason to buy a PSU. The Power supply is the most important part of the PC, because cheap PSUs when stressed will not only break, but they can also destroy all your PC's components and even start a fire. Suppose you're not in the house....
