REPLACE THE PSU, and hope you have not damaged your other computer parts!!! do not even try booting it again Period.
The PSU is NOT a place to shrimp on cost!!
(1) 22 buck for a 575 W PSU should have hit like a ton of brick, if not then the 142 out of 443 people who gave that PSU a rating of 3 or lower "eggs" (25% 1 and 2 eggs)
(2) A 575 Watt is way more power than you need. A i5-750 OCed, 5770 GPU, 2 HDDs, a SSD, a DVD writer and one Blu-ray writer only draws about 300 W Under full load, little over 100 Watts at idle. Newegg currently has the corsair 400 Watt on sale for 50 Bucks (w/10 MIR). AN Outstanding Company). Bought this for my wife's low end build.
Another, lower rated than corsair, but not junk eitherhttp://www.newegg.com/Product/Product.aspx?Item=N82E16817341017
I'm not normally this harsh, as I know money can be a desiding factor, But on the same token - Never forgot what my Pop said when I blew it. "Sympathy can be found in the dictionary between shi_ and Syphilis"
