Can OC effect CPU usage?

[Gandeh]

Set up:

990FX Mobo
1100T processor
V10 cooler


I haven't done any personal overclocking the motherboard has auto boosted my CPU to 3.8ghz from 3.3 which isn't too big a jump for the 1100T.

But I'm getting minor issues like firefox locking up for a few seconds. All I'm doing is running a Bit torrent and transfering a film from my computer to a USB. But my CPU usage is registering as this on the cores:

1: 30%
2: 6%
3: 10%
4: 12%
5: 8%
6: 15%

Any every so often one will jump up to 80% and then back down. Doesn't seem normal to me. Thoughts?

But I'm struggling to understand why there isn't enough, I have 16gb Ram and good cooling. So why would it be locking up?

Is there anything I can do to help the situation. It would seem silly if I can't do those three things without it locking up

Hmm I see, I'm running sata 3 6gb/s and have 1 SSD 2 Hybrids and a 2tb Baracuda green. So I would hope that wouldn't be an issue either.
