Icam stops working after a while

[Mujy4u]

I have 3 Foscam & 1 Dlink camera and I have Icam installed on windows 8. Everything was working great for a couple of months but now I keep losing some and/or all the cameras to whitish/grey screen. I would restart my computer and everything would be normal for a couple of days then I would have to do it again. Now 2 of the 4 cameras don't come back. Any ideas?

Are you able to access your cameras via any other video capture software? Also, what is the fps setting for each camera? Please drop it down to about 2-5 fps to see if that improves stability.
