Hello, everybody! I'm new here .Well I have a problem with my PC, the CPU is overheating it's about 55 C at idle mode and 75 C at Max CPU usage.The PC gives me BSOD's because of the CPU overheat. I Had this problem before but i bought a new Thermal paste and installed it into my CPU. It has fixed the problem completely but after 3 weeks the CPU has began overheating again... Also, when the CPU is overheating and reaches about 65 C or more I hear a strange sound from the CPU or the Cooler i don't really know also I think it can be coming from the Video Card but it's not overheating at all. My Hardware: CPU: Intel Core 2 Duo E4400 @ 2GHz Motherboard: Intel DG33BU RAM: 2.0GB Dual-Channel DDR2 @ 399MHz (5-5-5-18) Graphics: ATI Radeon HD 2600 Pro (MSI) Please help me , THANK YOU!
