Hmm, Vaio's are nice PC's. I have a Vaio Laptop, never gives me any problems.
Is it the first AOE game? There are three of them now and a number of expansions. accurate information is whats needed.
Ok, well a reboot is quite a serious bug, usually reboots are caused by graphics driver problems.
Patch the game to the latest version. Find the official site and do that first. Then go and update your Graphics card drivers.
If you have an Nvidia card go here:

If you have an ATI card go here:

Once that is done try again, if the problem persists then we can try the next level of expertise.
