I have an Asus U50F notebook. Specs: Windows 7 Home Premium 64bit, Intel Core i3 CPU M330 @ 2.13 GHz, 4.0GB RAM, Intel HD Graphics. For the past three days, for no apparent reason, I get frequent intervals of CPU spikes of up to 100% load on both cores. I've checked Task Manager and Process Explorer, and nothing seems out of the ordinary. This PC has always run at a consistently low RAM usage and core load. I'm not much of a techy, but any suggestions? Thanks.
