Cannot load webpages, multiple browsers out of memory?

Hi all,

I just got a new macbook air with SSD, 8gb memory... it was running fine all last week but this morning I'm getting all sorts of memory errors and page load problems across all browsers. I haven't installed/uninstalled anything and haven't changed any system settings recently.

Some pages load fine, both others load without stylesheets, others time out, and others throw memory errors:

Chrome:

Error 13 (net::ERR_OUT_OF_MEMORY): Unknown error.

Safari:

(NSPOSIXErrorDomain:12)

Any ideas?

Thanks in advance.
