Tried upgrading my old Acer Aspire 5335 from T1600 CPU to T9600 and laptop just hiccups at boot (shuts down and tries restarting). I have the latest BIOS so I'm assuming it won't work with the FSB of 1066Mhz for the T9600.

I've read in a post that a guy replaced his celeron with a T9300 in the same Acer 5335 laptop and it worked fine. The T9300 is a 800Mhz front side bus so I'm wondering if a T9500 might work but I don't have one to try (or T9300).

Anyone have any ideas or have a T9500 or T9300 CPU lying round they are interested in swapping for a T9600?

Thanks.
