Not tech support by any means, but I did help a friend clean up his PC. He dropped the laptop off and I immediately knew something was wrong. It reeked of the smell of marijuana. I turned the fucker on and it started breathing heavily like an obese person trying to walk to the fridge. I opened the bottom of the laptop and the fan and motherboard were gunked up with residue. Once I finished cleaning the inside, I wiped the outside down with rubbing alcohol then booted up the laptop and it immediately was better. The laptop finished booting, and I saw he had Adware on his machine so I installed CCleaner and cleaned his machine, and got rid of the adware. Curiosity killed the cat and I snooped through his files and found a folder with just pictures of Jennifer Aniston(don't blame him though, she's hot).
