hi
2 week ago after one dj set on a dance party
my multiface is fail get a all flashing LED ! no host error all led is flashing  !
i tested all votage inside the rack and the 5v drop down to 2v
tesed the 10v and drop down too (ic9 on hdsp pci is fail i checked him and see a burn black trace)
wiht this voltage the rack is not able to sync wiht the hdsp pci
i resolve the problem wiht a external power supply
and 2 week ago my hdsp pci is not recognised by seven
i get this error many time on my old computer p4 and resolve this problem wiht a new 4.7uf cap on ic6 
try a new cap and not recognised on seven
at this moment for me the hdsp pci is dead (maybe another regulator is dead)
i test all regulator on hdsp pci and ic3 have 3.28v ist ok for him and ic6 get 2.48v ist ok too
i try to test this card on my 2nd computer (my old p4) and get a blue screen on 2nd pci slot maybe a irq problem
try on 3nd pci slot but no dectect
try on 4nd pci slot is detected and succefully installed
i have this card for 5-6 year and get this error many time on my all computer
any time i resolve this prob wiht a new cap on ic6 but this time is not work !
wath's the problem wiht this card ?
best regards
