how do you improve your low memory on your pc ,i keep getting this yellow triangle
popping up in bottom right corner . its really slowing down my pc at the moment anyone have any ideas i would be really greatful if you could help thanx

You need to look up what kind of ram your computer uses, you can google the model number for its specs.

The icon you are referring to means your video card crashed and has recovered.. What is the specs on your system?? Could be a overheating issue.. Maybe a dusty system..
