Actually, the system boots up fine, but sometimes some sounds comes as
though there is a problem inside, and i am able to log in. When opening t
he
browser and scrolling through the page the browser just goes off; the sam
e
thing happens when dealing with PDF files.
I was firstly using using SL5.4, but then i had the problem of audio soun
d
and the previously mentioned problems, and also the system making those
"clutching" sound during booting and shutting down.
I moved to SL5.5 and the only thing that has improved being the audio.


cheers
