Graphics driver stops working, computer freezes?

[glp15]

Hi,

Over the last few days, my computer has been freezing. Before it freezes I repeatedly get a black screen flashing up and then a message that my graphics driver wasn't working but is has been repaired. It does this about 5 times, before completely freezing (ctrl + alt + del doesn't do anything). I have forced it to shut down and started it up, and it works for about 1 minute. At the time I was using microsoft one note (which I haven't had any problems with before), and google chrome, which I have only recently installed. I tried uninstalling chrome and using IE but it did the same after about only a minute of being switched on.

My laptop is about 4 years old, but I've only had problems over the last few days.
I'm currenly using safe mode, and I'm not having any crashing/freezing.

My laptop is a dell vostro 3500
Windows 7 home premium
Processor: Inter(r) core TM i3 CPU M330 @2.13GHz
Ram: 2.00gb (1,87 GB usable)

Could anyone advise me on what to do?
Thanks

try to uninstall graphics drivers and reinstall them. Maybe they could cause the freezes..

Has this laptop ever been fully torn down and cleaned?
At 4 years it's more than likely the internal heatsink that helps in dissipating the heat is completely clogged with dust it's sucked in over the years. The faults and black screen could be caused by overheating. Regardless if it's never been cleaned, it's time...
