9600gt HELP. Is it BROKEN???????

Hello, i have just bought an inno3d 9600gt i chill hurricane and i wanted to determine whether it was my graphics card or psu or motherboard which is broken or not goot enough. My psu is a cheap one (£10.00) bought from ebay (and the make is win power and its a 650watt psu, It works fine with everything else on my pc but my pc isnt excactly top of the range. The motherboard is an acer standard one, cant remember the excact make but it is on a acer m1610. I dont think its the motherboard because it has pci e slot so why would it have that if it didnt support it. My pc doesnt even power up when i put the graphics card in and then when i take it out it doesnt turn on until couple of times after i unplugg and plugg power cable back in. So i was just wondering if my graphics card is broken or i need to update something?

hope somebody can help and i will let people know when i find out and ill post whats wrong if anyone else is having the same problem.
