Video corruption using usb M4A79 Dlx

[Ren H]

Anybody experience video corruption/anomaly when plugging in usb device? (flash drive)
System:
M4A79 Dlx
Sapphire 4770
video capture card
All devices powered through APC Smart-UPS 750

problem occurs when viewing video from capture device and plugging in usb stick

- I suspect the problem may be due to bad (overvolting) camera but thought I'd ask if anyone has seen similar

I have this board and haven't seen anything like what you mention. Have you tried it without the UPS?
