PC won't start up with new PSU

http://pcpartpicker.com/b/pZYJ7P is the build I replaced the dying PSU with a Corsair 750 watt http://www.newegg.com/Product/Product.aspx?Item=N82E16817139051

http://pcpartpicker.com/forums/topic/58124-got-a-new-psu-however-it-wont-power-up-the-computer-however-i-did-the-paper-clip-test-so-it-cant-be-the-psu You can read some of this to figure what I'm at, at the moment(comments section mostly). Basically my PC worked last night, but then I turned it off and replugged the HDD because the BIOS wasn't recognizing it at all. After I did that, the PC doesn't turn on anymore. I best I got was a split second power LED and then an immediate shut down after. The fans started to spin for a split second and then stopped. The PSU works because my PC was working fine last night, except I was just trying to fix whether or not my HDD was dead or not. I don't think it is, but I'm not exactly sure about anything right now. I've reseated the RAM and CMOS unplugged power switches etc and still nothing happens.

So I think I've come to the conclusion that I some how screwed up my motherboard or something, because what else can cause a problem like this if it's not the PSU? And if the Mobo is fried, is the CPU still okay? Cause I would hate to buy a new CPU

almost sounds like you might have a short. did you unscrew the motherboard or tighten any of the screws in tighter. i would go around your case and make sure there is nothing that is touching cables or parts that might be contacting the motherboard or other components like the graphics card that shouldnt

Well idk wat exactly am I looking for everything to my knowledge is connected to the motherboard. All the appropriate cables and everything I didn't even really touch or move the mobo since all I did was connect cables from the psu to the mobo

Do what Madcracked said, but also try taking out the HDD again and see if it turns on. It's quite strange but from your description it sounds like that's having some effect.

Yea I've done all that now and I think I've come to the conclusion that the mobo is dead. I just hope the CPU is okay and the HDD is okay. I'm gonna see if I get one of my friends to test the hard drive on his computer. Out of curiosity is there any motherboard that you recommend atm or should I wait for black friday and stuff.
