Blackscreen after changing CPU -pls help-

1,165 Views

Hello,

I've buyed an Intel core duo T2400 for my Acer Extensa 5230.

When i put the CPU in and start the Laptop i get only a black/no screen.

The Status LEDs and drive works fine but there is nothing on screen.

After a few seconds the PC automatically shuts down and restarts.

When i put my old Processor in everything works fine again!

When i touch the CPU (T2400) its really hot and i tried Thermal conductivity Paste (sorry if its the wrong word,im not english) but theres again just a black screen.

Ive got the latest BIOS version.And i think the CPU is compatible with my laptop......

It seems like the PC/BIOS/Mainboard does not detect/accept the new CPU?!

Is there anything i can do?

Please help me....

Thanks,

Severin
