Disconnect all drives. Now boot-up and hit the bios key sequence to enter it. Will it do that? If yes, allow it to display for several minutes and once there be sure to check all settings. if it doesn't do that, you do have some glitch or power issue.
If it works or stays power-ON then re-attach everything. Be 100% sure that any cabling is the proper setup and connections. Also, because you have XP and SATA connection, did you get to supply the drivers when prompted during XP install do that? Not only that but the right ones, your old mtrbd. doe have SATA connections? it isn't being supplied by adapter? Also, did this ever work? If it did, what has changed?

i seem to have encountered a power issue with an old mobo i borrowed from a friend: it wont power on.
it used to work as normal until i got to the point of installing winxp onto it. it just shut down. now whenever i try to power it on, the fans spin like halve a rotation and stops, nothing further happens. the green LED is on. the ram sticks are good -tested them when the mobo powered on as normal. tried 2 different psu with the same result. it cant be heat build up; i moved the mobo into my haf922 mid tower case and even reapplied thermal paste to the cpu just to be sure.
any ideas what i'm missing?
