Specs: Windows Xp
Recently my laptop screen goes completely black after a few minutes of using it. I hooked up an external monitor and it also goes black. It also flashes rainbow colors but not as much as just blacking out. Is this a video card problem or something else ?

Since you hooked it up to an external monitor and it does the same thing, it's a video problem. Laptops don't have video cards, the video comes from a chip on the motherboard. It sounds like an overheating symptom. Get a can of compressed air and see if you can blow out the vents. If you can open it up, you should clean the inside as well. Try elevating it between two books or something similar to help airflow under the machine.

I use a little stand for it that plugs into the usb port. It has two fans and keeps the laptop pretty cool. It doesnt get nearly as hot as it used to...
