Hello. I recently bought a 9800gtx and have been trying to install it myself despite not very much knowledge about computers at all. I remove my old graphics card, insert the 9800gtx and connect the white/transparent things from the card to the computer. I boot up the computer and get a "VGA - No Signal DVI - No Signal" I'm not really sure what I've done wrong. I've heard something about power supply but I know nothing about it. Are they different from EU to US? (I'm EU). Thanks.

Input voltage is different, but output voltage to the computer components is the same. --Does that Packard Bell's power supply provide enough juice to power such a high-end card? --Did you connect the two 6-pin PEG power connectors to the card? If you did, did you have to use a Y-adaptor for the second power connector? If you did, then your power supply wasn't designed for such a high-end card.

I had successfully installed and play the Crisis Games by 9800GTX but unfortunately the motherboard BIOS crashed because of CMOS Reset button pushed and jamed. Motherboard has been changed by new one but no display and after turn on pc, power goes to auto off. Pleae help me. Is it my 9800gtx goes crash?
