Earlier today I made a thread about this already and people suggested that I dust my pc out. That is what I did and my pc stopped shutting down until now. Now it started happening again. It shuts down the moment I enter the game or after I play for a while. The temperatures are normal, I checked them. The cpu around 60°C and the gpu a bit below 70°C. So since I just dusted my pc out and the temperatures are normal, its not an overheating problem and I am guessing that something is broken. I tested my ram, cpu and gpu a while ago with all kinds of stress tests and everything worked fine. People told me that it might be the psu. What do you guys think?
4Gb DDR2 Ram
Intel Core 2 Quad
ATI Radeon HD4890
Update: I just enabled System fan 1 fail warning, Power fan fail warning and System fan 2 fail warning in bios and it beeped all 3 times, so does that mean that those 3 fans are the problem?
