I have on three different occasions had a most peculiar problem involving the above noted card. The host machine has failed on two machines (BSOD), and displayed very erratic behaviour with major slowing down on the third. On all three machines the problems ceased completely when the machines were taken out of their usual location. All three were in domestic environments (bedrooms/living rooms). At the first location ALL electrical equipment in the affected room was switched off (at the mains) and still the behaviour persisted. Changing the mini PCI card cured the problems. Once removed from the affected locations the cards work perfectly. Has anybody heard of a location based failure of this kind with these cards?
