3 Years ago i did buy a complete PC (before i always builded them by myself), because it was a good Offer. In the last Time, the Son of my Girlfriend was playing some newer Games on it and the PC sometimes was getting a "blue Screen" or shutted down completely. Because i never did have any Problems in the Past, i thought i start with checking the Temperatures of GPU and CPU and so i installed the msi Afterburner and displayed the Temps of all 8 Cores while playing these Games. There i could see that the Temps of the CPU Cores was around 110 to 120 °, which is much too high. So i set the CPU Cooler Fan to "always full" in the Bios, to see if that cools them down. But that didn't help at all. Then i remembered, that it can happen, that the thermal Paste, that gets used between the Chip and the cooling Objekt, gets dry and crumbling. So i did buy that Paste, opened the PC, removed the Cooler and did see that it wasn't dry and crumbling. But then i did see the Reason for the Problem. On the Surface of the Cooler, where the Paste is, there still was a Film with the Warning: Please peel off label before you use it So i (of course ) did that, removed the old thermal Paste from the Chip and the Cooler, applied the new Paste and mounted everything. The Temperatures of the Cores was between 50 and 60 ° now and i could set the Cooler Fan to it's normal Setting in the Bios again. Now the Temps are between 55 and 70 ° and the blue Screens and Shutdowns seem to be gone. So sometimes a small "cheap" Thing can cause big Problems and it doesn't always has to be the Hardware itself that causes Problems.
wow, that's crazy. Unbelievable. Someone left the sticker on the cooler! Happy you found the problem. My PC was going through bluescreens also not too long ago. One of my 4 DDR RAM sticks was going poorly. Removed it and all back to normal. No more bluescreens.
