Anyone who could help me out with this would be great.

I got a core i3 cpu with 4 gigs of ram, good video card, whole 9, and was having no issues streaming using the encoder at max settings 29.97 fps and 800 birate, while using manycam and using maybe about 15-20% cpu resources.

Just recently now I can't even run the encoder with just my camera and no manycam without it spiking and staying to 100%. Can't even stream at all, is it possible something is wrong with my computer? I did a system restore, virus scan, and everything and nothing is turning up, so my only option at this point is thinking maybe the computer is not cooling down properly (don't hear the fan kick on that much) or something along those lines?

Please help - cause since I did the system restore I can't stream at all, and yeah, I need to work.. its a rented laptop so I do have warranty on it I'm wondering if I should get it looked at and try a loaner.. any input would be helpful, thank you.
