Problem: The computer started to randomly shut down overnight. When I would try and turn on the computer at the start of the day by pressing the front power button, all of the fans would come on full blast and just continue running for several minutes at full speed, but the displays would not come on and the computer would not boot or do anything. I would then pull the power cable from the back of the computer, wait a few seconds and plug it back in. (Sometimes having to repeat this step several times) and the computer would eventually come back on and give me a warning saying the computer shutdown because it overheated. A few weeks ago the machine took approximately 30 minutes of unplugging the power cord and doing everything I knew before I got it on. I them downloaded a bios upgrade, and restartedupgraded the computer,bios and at that point I could never getshortly after the computer to turnmachine stopped turning on againcompletely.
