Sometime I practice my guitar. But I usually tune my guitar by my ear.
Once I want to tune correctly but I found my tuner has broken after I used it.
Maybe i'ts time to get something repaired

My tuner

I found the problem after i opened it up
The buzzer in tuner was cracked

So I just bought another buzzer and try weather will it works or not

While I was doing this I was very carefully, I was afraid that make something else broken.

Then Finish.

The tuner works again after I just changed the buzzer.

Few days ago, math teacher from school brought me an old Acer because his computer need restore. (The computer has so many virus)
I found that the virus made the windows crash so seriously after I checked up.

Acer Aspire M3300 (Rate seems good)

Some details about computer

I plug my monitor and some stuff to the computer

Inside

Choose USB - Compact to boot
And I put Windows 7 Ultimate into the USB

Installing

Done !

Finally I just install drivers and some common software.
I return the computer back after all. ( And the teacher looks happy)
