|||If you plugged your video card into the old PSU of 300W, then you've fried the card. It's OHMs law (resistance) -- I'd send it off for an RMA or exchange.|||Right-click on My Computer and hit properties, go to the hardware tab, and open the device manager. Look under display adapters to see if your computer detects the card at all. If it does, just enable it by right-clicking on the desktop, going to properties, click on the far-right tab, and selecting it as your video card. If it's not in device manager, it could be a faulty card (or slot on the motherboard).|||go to your bios and set it to PCI-E or pci-express,but not PCI otherwise the bios will only detect any PCI gfx cards on the first PCI slot which is not what you're supposed to do and furthermore what PSU(power supply unit) did you buy, a cheap nonbranded 1KW PSU is worthless as because it will have a maximum of 18a on the 12v raild and dont even get me started on the design|||did you run the software after plugging it in,the driver software,this what i did disable my on board graphics through device manager,turn off ,plug in my video card,restart,cancel found new hardware,ran my driver software,make sure direct x has the latest

updates , config my display settings,went to the nvidia website for the latest updates .|||Look at the products' manual carefully and find out.|||don't know too much bout computers but don't you have to disable the other card first.



idk.. jus a suggestion..
