I recently purchased this in a bundle complete with an AMD+2 5200 dual core, 2GB 667 ram as a replacment for my old faithful PCChips M810l. I reloaded XP using the dvdrom cdRW drive np, then when all seemed ok I connected a flying lead from the back of the optical drive to a 4pin header, this flying lead used to be connected on my old board also. When I swithcd on smoke came from the case and this flying lead just about melted, luckily I seemed to have switched off in time as the puter has worked ok since, is this lead not needed? what was it for? The board header was marked CD-in and the plug was the same pitch so it had to go there? any ideas pls.
