I will be simply browsing the web and everything will stop responding and I'll wait for 5 minutes or so and sometimes it will respond again but usually I have to shut off the laptop. Not even the classic CTRL+ALT+DELETE works, the keyboard doesn't function when my laptop stops responding so I am forced to shut off the laptop.
Does the mouse freeze as well? How about the screen - does the clock keep updating the time, or is it frozen at the time the keyboard stopped responding?
ctrl+alt+del bypasses all of Windows and sends an interrupt directly to the system. That's why Windows server uses it to login - it can't be faked remotely or by software, or blocked by software. If the mouse and/or screen are not frozen and ctrl-alt-del doesn't work, then you probably just have a defective keyboard. Try plugging in an external USB keyboard and see if that still works when your laptop keyboard freezes.
It's odd because when I'm using Photoshop or something the computer will be just fine.
If the mouse and screen also freeze, then it sounds like you have a hardware/driver problem. The browser is causing the computer to try to use that hardware or driver (maybe audio or video?), while Photoshop does not.
Edit: How much RAM are you using, and do you have virtual memory turned on?
