Internet connection lost when CPU% goes up

Hi,

I have MBP aliuminum, running 10.6

When I use chrome flashplayer or quicktime or torrent, some times, veryoften I may add, the internet goes off. I can't find a solution. Anybody has any idea?

Thank you for your reply guys, I hope you can answer me this after giving more info.

Yes, is quite old, is a MBP2,2 2007 2.33 inter core duo with 3gb 667 ddr2 sdram.

When I used ethernet or wifi, it gets disconnected. Only happens when I have one of those three elements open (torrent, chrome with flashplayer on, and quicktime). I see in my Activity monitor how the CPU% goes up with these three, fu***ng chrom helper makes most of the mess and the kernel_task goes up, it has to be memory I imagine, but it didn't mess up like this before.

Now my new question is. I clear OSX install means all of my stuff will be gone, if I restore it later with my backup, which is a mirror of what I have now, it will be the same at the end right?

THanks.
