I think you better replace your PSU soon! If you search this site, you will find an immense amount of information about eMachines.

Yea thats the problem i had before my power supply fried and took out the motherboard. You still have a chance to change that PSU though.

I'd use this power supply. Newegg's an awesome place to buy from.

I would go with this PSU. http://www.newegg.com/Product/Product.asp?Item=N82E16817104952
FSP has a far better reputation than thermaltake when it comes to powersupplies and it is only $37.

Hopefully motherboard damage hasn't already occured.

What are the specs on that PSU? Newegg's site is currently having problems; I can't view the page. It wouldn't show me the page when I tried to search for something, either.
