I bought a Philips 7130 PCI TV card. It works fine on my other Pentium 4 PC I use regularly. I couldn't carry the PC with me so I took everything I was going to need: hard disk, DVD drive and the TV card. The other two work fine, but the TV card isn't even recognized by the system, it's not there in device manager though it's firmly inserted into the mobo. The PC specs are: Intel Pentium II 398 mhz, 128 mb sdram, Seagate 6.4 gb hdd, ATI Rage Pro 4 mb, Windows XP Pro SP 1 (it's magically slow). Why can't the TV card be recognized by the system?
