Wareless PCI Card causing DPC's

ok so my Dad's computer was running reeeeeeally slow, so I told him I'd look at it. I ran procexp and found that he had very high levels (30% each) of interrupts and DPC's. I narrowed it down to the wireless network card I just bought him (since I just set up a 5 computer wireless network here). If I disconnect his wireless connection, the DPC's and interupts immediately drop to 0%. I tried updating the driver, and I tried moving to a different PCI slot, but neither fixed the problem.

I guess I should probably return the card and get a new one, or maybe a different one. Posting this here in case someone knows something I don't, though after searching the net for information on DPC's, there doesn't seem to be too much info on what to do about them.

much thanks.

 

I would try the new wifi card in a different PC. It could be faulty.... if it does the same thing in another PC... well.... you know what that means
