Why do you THINK it's fried? We'd need a lot more of the backstory to even begin to answer a question like that.
Generally speaking, if it won't boot using the memory you have, trying only one stick at a time, and it will using other memory, there's a good chance it's bad or "fried". You may need to borrow or buy at least one other stick of memory to find out if it won't boot at all using the memory you have.
Are you getting any error codes when you try to boot the system? Does your motherboard have an error code LED on it, or do you have a system speaker attached to the motherboard in order to hear beep codes? If you do not, it will make it more difficult to determine than if you did.
