So my moms computer was acting up, so I broke into it and dusted it out, as well as checking all the connections and such. All looked good, so I put it back together and plugged everything back in. seemed fine, till I tried to turn it on... It refused to even start powering up... So I look at it and note a blinking green light on the psu... So I google it. Seems like most responses say psu is bad and you gotta replace it... Till I found the mcguyver response, lol. HP suppprr forums had a nifty little method l. You take a hair dryer and blow it on the fan of the psu until the light turned solid...so I tried it. And it fricken worked! I ran the hair dryer for like a min or two and it turned solid and the computer turned back on.. It was pretty damn epic. We'll still need to replace thePSU most like, but at least I got it started up again.
