Built a computer

[Prometheus]

Specs
Geforce 9800 GT 1gb DDR 3
Intel Core 2 Quad 2.3 ghz @ 1333
Gigabyte S-Series Ep43-ds3l
4 gb Kingston Value Ram ddr2 pc2 6400 800 mhz
Samsung HD 1TB SATA (for storage)
Some random 160 GB SATA HD (for OS)

So first I put all this together with a 450 wat PSU...

No dice. The PSU popped and I had to replace it..... with a nice Antec 550 W psu...

Put everything back together and plugged it in and flipped the PSU switch! and it came alive! LED's Fans, CPU, GPU HUZZAH!!!!

Only problem is now when I plugged it into my dads monitor (the one im typing on right now...)

nothing came up...theres no beeps or anything...just the CPU running and the sound of things coming to life...

I'd like to think that my CPU has not been fried by the PSU pop...but its possible, though I'd like to think that there is something blatantly obviously wrong with it that im being a knuckle head about.


any thoughts?
