Well. I went around the internet about why my PC isn't starting up any games and I found a site that tells me it's either: My PC is crap(It's not, it's been working before.) the temperature inside is too high. (I tested, it's not) It's dusty. Yeah, the fat guy told me it was dusty. I'm not bothered to open up my PC and I don't think you can solve this problem by picking out individual dust bits. So is there a way to clean off the dust without opening my PC???
No. Just turn off your PC, unplug it, open the case and gently clean out the dust. If you have it, use some cans of compressed air to remove dust gathered around the heat sinks/fans on your processor, video card, power supply, etc. Just follow the instructions on the can. Most of them you have to hold upright, don't shake, and don't use for long periods of time. It all has to do with the compressed air cooling the surrounding air and causing condensation. You don't want to spray water everywhere. Follow the instructions on the can and you won't have that issue. The temperature inside your case may not be too high, but if heat sinks and fans are clogged with dust then your computer's individual components may not be dissipating heat properly and can cause errors and such. As far as errors on games, what games are you trying to play and what are your computer specs? Operating System, Processor, RAM, Video Card.
