I have been building computers for myself, friends and family for 10ish years. Not the longest career in the biz, but I definitely have the modern relevant bits down. Computer tech in general is a hobby and interest of mine. I'm more confident and interested with hardware problems than software, but can do both in many cases. I'm not trying to make a serious business out of this, but figured I could help some people out.
I can try to diagnose hardware problems, fix overheating components including laptops unless they're permanently damaged, upgrade just about anything that can be upgraded and help clear out junk in Windows that you probably didnt know you had.
