Hem i got some updates!
I think i found out the problem : my hard disk is not being recognized!
I noticed that when windows doesn't boot and i access Bios i can see that as master 0 and slave 0 ther's NONE while as master 2 thers my dvd reader
Today my pc was working perfectly , i went in BIOS and saw that this time as master 0 something popped: MAXTOR STM3500320AS ...that's my hard disk!! but could this really be the problem? would it justify the OS freezes and slowdowns?
And if Yes , is it necessary my hard disk the problem , or maybe it could be vista that doesn't recognize it?
Please if you can help a noob like me , do it !
Thanks in advance,
Nemar
