Hi everybody.
Today when I came to turn my laptop, it booted into BIOS screen with "Press F2 to enter..", and then it switched to a black screen with two letters 'Y'..
Now I have read a little bit on forums but didn't really find any solution.

Specs: Acer Aspire 5745G (i7, 4GB RAM, Nvidia GT420).
Windows 7 Ultimate 64bit.


Any help is much appricated!!
Thank you.
