I'm installing an HIS Excalibur 9800 Pro, but after plugging in the card and the power connector, my PC won't boot up. Instead, it immediately goes to standby mode. When I reinstall my old graphics card, everything works fine. As far as I can tell, I meet the recommended system requirements.
My specs are:
Athlon XP 2400
Gigabyte GA7DX (rev. 3.0)
512 MB
Antec TruePower 330
Windows XP
Any ideas what the problem might be? Thanks in advance.
