I have a problem my pc has been falling for a few days and I do not know why. It would be of you to hear a few normal theories or what I could do best.
If your laptop's CPU does not overheat due to dusty vents and fans, it could be broken hardware in the worst case, or at best just a driver or system problem.
If it should be the bad dust: just blow with an air pressure compressor in the vents, until it no longer dust.
And if you get a blue screen, it's usually at the bottom that caused the crash. In most cases then stands u. A. Something from ati or something like that, which points to defective drivers of an AMD graphics card, which should then be replaced by akutelle. Of course, other broken drivers can crash the laptop.
Finally, you can reinstall the operating system. If there's no hardware problem, the error can already be solved.
