Well here's what happened. Yesterday I went to subway and when I came back my monitor was off, my mouse turned off, and the light on my hub for my computer was out. Now when I turn it back on I can usually last about 30 minutes until the same thing happens again. Sometimes it doesn't even turn on though. The only thing that I noticed is that my core0 voltage is way low. I have a 900mhz t-bird on a msi k7t pro-2a and the voltage is only 1.55 if I have the voltage set as default in the bios or 1.7 to 1.65 if I set it to 1.85 in the bios. Could this be the problem? I have an antec 300watt powersupply so that should be good. I re-greased and re-sat my heatsink also. Thank You
