Sattellite shuts off, screen starts blinking, and many other problems

Question

Hello
About a year ago i bought a Toshiba Sattellite L855-149. And the thing has been nothing but problems and inconveniences. Not what you'd espect for an 800€ Laptop.
First time i tried to connect to wireless network, blue screen. Happenned a huge ammount of times.
It constantly freezes and goes into a state of "coma". But that's not what I'm here for.
So, I was playing (NFS ProStreet, a game a computer like this should run without even trying), and it decided to shut down. Not in a "normal" way, it just went off as if the power source had been removed, evenb though it didn't. But, this had happened many times before, so I just did what I always did, waited a couple of minutes and, when the power source lightn lit up, I started it. However, instead of starting normally like it always did, it said something about an update, and then the screen just kept turning on and off, like blinking. A couple of seconds lit (altough it didnt show eãnything- just a black screen) and a couple of seconds off. Now everytime i try to turn it on, the Toshiba screen shows up for a bit, and goes back to flashing.
Another thing that I can't understand, is that i can't access the BIOS. I've tried before, with all the F's and with the Fn+F keys, but nothing, it just ignored me.
I am really mad with this laptop, and with toshiba in general. I don't know if someone else had this problem or not, but i think it is unnacceptable for an 800€ Laptop, that was ALWAYS treated with extra care, to give me problems like this.
If someone could help, I would very much apreciate it. It still has a warranty (as I said, it's barely 1 year old), but I wanted to avoid taking it where I bought it for repairs, as that could take months, or even years, and probably wouldnt solve anything (like it happenned before to my father.
Thank you in advance
PS: I DO have a cooler, and the computer was barely hot, so I don't know what caused it to shut down so abruptly.

That doesn't appear to be a US model, and this is the forums for Toshiba USA. You may want to contact Toshiba in your region.
If it's a European model, you could check the Toshiba Europe forums.
