Hi guys i have a little problem with my laptop toshiba l505 core2duo.

the problem is i can use my laptop normally when the Core Multi Processing its disabled, but when i activate it in the bios, the laptop starts to crash, restart, and sometimes it doesnt even pass from the login windows logo.. what could it be?
