Computer stopped working. Help please.

Hi, I have a computer thats been working for a while now. Yesterday it started acting weird. Whenever I started a high-graphic game or ran a couple videos at once, the monitor would go into auto power save mode and my computer would freeze. This happened to me a year back also but it only happened when my old video card heated up to over 80c+ (Now I have a new video card).

Today, I get the "entering power save mode" error right when I press the power button.
I tried replacing the RAM, cleaned the dust, re-plugged the cords, and it still won't work. Sometimes when I turn on the computer I get four beeps, but sometimes I don't get anything at all. There is a bright red LED light on the top right corner of my motherboard next to the RAM slots, but I have no idea what thats suppose to mean. My computer used to work perfectly fine until yesterday. I would appreciate any help if possible.

Thankyou.

Four beeps has a lot of meanings, what motherboard do you have, and it is not always likely that a red light next to RAM means bad RAM, never the less, try popping out the ram and booting one stick at a time if you have more than on stick. also if I could have the motherboard name that would help.
