Today I boot up my PC, click on my user account(I use Administrator) and as soon as the text-box for entering password appears my computer stops responding.
The cursor is moveable though, but has a frozen hand icon(like when you hover over a link on the Internet).
When computer boots up, for about 2-3 seconds up until that "Verifying..." message on black screen I hear a strange ticking coming from motherboard's speaker. It seems to make sound in rhythm with the appearing text upon boot up.
I tried safe-mode, but it freezes at the same spot.
