Computer problems

I hate my computer...

Since a few weeks, my PC doesn´t work. There´s nothing on the screen sometimes, or the whole screen is full of colourful stripes...Or it works for a few minutes, then goes out. And when I press the On-Button, sometimes the PC beeps 2 times fast and 8 times slow.

Good thing I got a laptop on my birthday. I can´t live without computer and internet. Don´t wanna imagine: no Ebay, no MAL, no anime and manga...OMG!

Anyway: If someone reads this and can help me, please leave a comment.

Arigatou~
