|Obviously my other response was a joke (sort of). We can't help you if we don't know what you have. Telling us you have a "high performance desktop" isn't helpful. Is it a custom-built PC or OEM (Acer, Dell, HP, etc). If it's an OEM, please state the make/model/model number & if any modifications have been made. If it's a custom-build, please list the complete specs in as much detail as possible - CPU, motherboard, RAM, graphics, HDD, power supply, etc.|
Had the PC been working OK & then this problem started, or have you been having the problem since day one? Did you make any hardware or software changes that may have brought this on? Not sure how old it is but when's the last time you opened the case & blew out all the dirt/dust that's accumulated inside, especially on the heatsinks & fans?
