There are a couple of possibilities, and it (somewhat) depends upon what version of Windows you're running.
If you replace a single-core CPU with a dual-core CPU, Windows XP and Win2K3S should detect the change and change the system type from uniprocessor to multiprocessor automatically, and load the appropriate driver. For Windows 2000, go into the Hardware Device Manager, find the "uniprocessor PC" entry, right click, select "update driver", click on "display list of known devices" and find the multiprocessor PC driver. You'll have to reboot. For the 2nd option, I would recommend Ghosting your system beforehand, just in case. Knowing a bit more about your OS and hardware would be helpful. You can also find better info (and respondents who are far more knowledgeable than myself) at online forums such as the Ars Technica OpenForum, http://episteme.arstechnica.com/eve Pete Pete ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Upgrade to Adobe ColdFusion MX7 Experience Flex 2 & MX7 integration & create powerful cross-platform RIAs http:http://ad.doubleclick.net/clk;56760587;14748456;a?http://www.adobe.com/products/coldfusion/flex2/?sdid=LVNU Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:268596 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
