    Lately, my computer has been shutting itself off suddenly, followed by a loud high-pitched constant tone, which lasts until I turn the power off on the power supply. When I turn the computer back on, I get a blue screen that says there was an error and the system has been shut down. If I leave it off for about 10 minutes and turn it back on, it will come on fine, but eventually shut off again. A friend of mine mentioned that this may be a motherboard issue, so I'm just wondering what everyone here thinks.

    Thanks

    maybe a temperature problem
    if you switch back on and gointo the bios do you have a pc health area you can look at CPU temperature settings

    usually the noise warning is a twotone alarm - but it may change with a different bios

    how old is PC = it may be worth taking a vacuumcleaning and opening the box and getting rid of dirt and fluff from cpu fan and other fans - be careful you dont dislodge anything

    AHHHH. I had my response all typed up and right before I hit Submit, I accidently clicked the "Back" button on my mouse....grrr, ok, here I go AGAIN.

    I don't think it's my CPU fan, I just installed a new one a little while ago, cause my old one died on me. I also keep one side of my case open because my temp gets too hot if it's all closed up.

    Here is the info from the Sensors View:

    Temp:
    Cpu: 36C / 97F
    Sys: 34C / 94F
    Aux: 57C / 135F
    HD0: 48C / 119F

    Fans:
    CpuFan: 4688 RPM
    SysFan: 0 RPM
    AuxFan: 0 RPM

    I do have a second fan on my motherboard that IS spinning. I also have a second hard drive that isn't showing up.... Also, as I type this, I am getting alarms from Sensors View that my CPU temp is spiking to temps between 80C/171F - 85C/185F and then drops back down to the temp listed above. I don't know what could be causing this.

    Your temops are acceptable but the spikes show the problem and I would just bet the fan is either not on full all the time or the heat synch is full of crud or the heat/synch and fan need cleaning off cpu grease and reapplied layer of Arctic Silver...

    Well, I haven't noticed the fan speed slowing at all, so I guess I can try cleaning it. Where can I get Arctic Silver, should pretty much any PC retailer sell it?
