I’m having a problem with a Creative Sound Blaster XtremeGamer SB0730. It randomly causes system slowdown and slow booting in Windows XP, Windows 7 and Ubuntu. It’s not software because the problem was fixed by swapping it with an identical card and the card caused the same problem in 3 different motherboards. Nothing appears wrong, no bulging capacitors or burn marks. If anyone has any ideas as to what is causing this or a way to fix it, I’d like to hear about it. Thanks in advance.
