Hello,
i just built a new computer. Installed all the parts powered on booted up windows 7 (preinstalled on SDD). The problem starts here. The system runs normal and fine but mysteriously powers off/turns off. It is almost like something is shorting or a heat index is reached. However all the temps are normal and i have swapped out the PSU into an older computer to see if it was shorting..it's not. I checked to make sure nothing was touching the back of the mobo, good nothing there. I RMA'd my mobo thinking there was an issue with that, installed the new mobo still have the issue. Swapped ramm out still doing it. I thought maybe the drivers needed updating nope still doing it. To further describe the issue, I have to remove voltage (turn off the PSU on back) and turn it back on for it to restart. Please help any tips or suggestions?
