fix my pc plz
 

at first I thought someone down the street was running their lawnmower, but it was actually my desktop computer. I powered it down and now it won't turn back on. I'd like to preserve what I can, if it's possible. My first thought was that the problem is the power source/and/or cooling fans. but I really don't want to spend a fortune replacing the parts or even buying a new desktop, especially if it turns out the damn thing is fried.

any experiences with something like this? or know what the issue could be?

I really would start with the power supply. If your PC is a stock one (whether off the shelf or just made by a company like Dell), the supply probably sucked in the first place. Plus, unless you put in your own power supply, you can almost certainly get an equivalent or better for cheap. It's not an expensive part to do a test run with, I guess is what I'm saying.

Out of curiosity, what do you use your PC for?

i use it to rule the world. and yeah it's a dell. i'l just try to buy a new power supply and see if that works.

Which is why I was wondering what he used it for. Most stock power supplies are pretty low-end in terms of endurance and in terms of the power actually supplied. Even boutique "gaming" PCs often come with supplies that are really too low to supply the power recommended for their video cards.

But if you don't use a video card (gaming, video processing), you probably don't need that powerful a PSU.
