the virtualisation capability is an option in the bios; that is where it can be anabled. To get into bios begin the boot up process and hit the delete button continuously. On some boards it is the F2 button but it should be the delete button on your board.
Remember to save the option on exiting.

I don't see the Gateway GT5238E motherboard supporting an Intel Core2 Duo E8400.....

The motherboard in the Gateway GT5238E has an Intel G965/Q963 motherboard chipset.

You can find a list of supported processors here: Intel Desktop Board D946GZIS Supported processors and here: Compatible Processors.

Hello visit your pc models homepage in seach for the drivers.

Or search by the mainboard number with google.

Good luck

If your pc worked fine before then why it shouldn't support. Consider the following :

# Check whether you have insert the processor to the motherboard firmly or correctly (your pc won't boot if you fail this condition)
# Check whether you have insert all the power supply cables in place if you remove earlier
# Check for any unusual events after or before you switch on

It's the motherboard - the processor would have violently overheated if it would have drawn so much power.

Nope. because it only accepts AMD processors

check your BIOS.

personally i have the q6600 which is a quad core processor, all the others you listed were dual core, personally i use alot of programs all at once which is good if you have a quad core, but just for general music, data, and streaming, the e8400 is probably better for you, its a 3ghz processor.
