Good night.

I'm having a lot of trouble with my computer recently. It's actually quite old (like 6 years old).
My configs are:

Intel Core 2 Duo E6750 @ 2.66GHz processor
ASUS P5LD2-X/1333 Motherboard
2GB/800MHz DDR2 RAM
GeForce 8600GT Video card

Long after my father bought me this computer, I realized that this motherboard does not support 800mhz RAM (supports only up to 667mhz). Nevertheless, it worked perfectly for more than 5 years.
Recently, my video card (or so I thought) started failing. Most frequencies of red became just black (thus making purple stuff just blue), and some frequencies of green became yellow. I plugged in my TV to test whether it was the screen or the video card, and the same thing happened (red->black, purple->blue, some cases of green->yellow). Even though it wasn't pretty at all, I did nothing about it.
More recently, though, I started experiencing some crashes in Chrome, Firefox, Skype ("Skype has stopped working and will now shut down") and League of Legends (a game I play), several Bug Splats in LoL and some cases of blue screen (often while playing LoL). One time I could read "MEMORY_MENAGEMENT" in the blue screen before my computer restarted. On this specific day, Chrome was crashing so frequently (like every 30 seconds) and I couldn't even open LoL sometimes, so I downloaded memtest an ran it. After kind of a long time and a lot of "enter" pressed, it tested 0,5% of my memory and found 136 errors. "It must be the memory card", I thought.
But two days later, the computer was running smoothly (except for the colors) and no error was found in Memtest. And it was fine for like 3 weeks, until today it started crashing again. I ran memtest and it found like 2k errors in 20% tested. Also, my mouse would stop working sometimes, making me unplug and plug it back several times to make it work. I tested the mouse in other computer and it worked perfectly.

This package of errors together made me think the problem was my motherboard, but I really need some light on this matter. Is anyone here able to help me?

Sorry for the not perfect english and thanks in advance.

Just to throw some more information I might have forgotten:

I have only one memory stick.

Sometimes, even when the computer was "ok", it would start beeping and I'd lose control of my character while playing League of Legends for like 3 to 5 seconds.
