Netwk card makes whole PC to freeze/jerk/freez when scanning

Specs: Windows 7, 4Ghz i7, 8GB DDR3
Hi,
I bought a new PC in April and it is good and fast for games except it has one very annoying bug that I can't fix that it has had since the first day. When the wireless network connection is searching or having trouble finding the router or it drops, any application I'm using, even if just on the desktop, starts to jerk. The mouse will skip from point to point, and any sound playing will freeze in those same moments, any game will freeze for about two seconds-jerk-freeze-jerk.
I can stop it by either turning off my wireless radio or by choosing my network and clicking connect (if it is successful).
It was previously just using Windows networking but I have installed the Add-On networking application for my adaptor but still no luck.
I would never think that it could effect the whole computer in this way, any idea on a fix or the cause of it?

"When the wireless network connection is searching or having trouble finding the router or it drops"

Why is it doing that? It should connect on bootup & stay connected. Fix that problem & the other will go away. Why is it that your desktop isn't hard-wired (ethernet cable) to the router?

Thanks for the reply,
I live in a large shared rented house and so connect via wireless. There's no chance to make it 100% stable.
Although even if if I could I'd still like to know why my PC is paralysed by the occasional drop in connection/strength.

I don't know if the dropped connection is the cause of the problem or a symptom. At my house, I have a hard-wired desktop & anywhere from 1 to 3 wireless connections to my network at any one time - I never experience drop-outs. Have you updated the wireless drivers? Updated the wireless router firmware? Scanned for viruses or malware on your machine? Checked which apps you have loading at startup by running MSCONFIG? Do you regularly run a cleaning program such as CCleaner-Slim?
