hi i have an MCP73vt motherboard with an intel 1.8 dual core cpu. all was well until the unit suddenly lost its power light and the unit boots up and after about ten seconds shuts down. if you disconnect the 4 pin power connector the unit will stay booted with cpu fan funning at full wick but no video output, on reconnecting the four pin power connector the unit boots then ten seconds later shuts down. there is a removable chip near this four pin power socket I wonder if its that that has gone west or if the board has gone up the creek. Any ideas The bios chip is in another part of the board but this removable one is right near the socket that seems to cause the problem the chip is marked v421D1 BCA4
ok tried the separate graphics card but no joy all power connected to the board unit starts but no beeps from the bios and six seconds later the unit shuts down ? the reason I sugested the small chip near the four pin connector is just that its near the connector that when connecter seems to cause the board to fail if you dont connect it the board stays on but with fan full pelt. Dont worry I wont run it like that so any ideas on the fault or is it a gonner?
hi tried that even a replacement cpu still the same no beeps from bios and shut down after 6 to seven seconds. One thing since this fault has appeared when you switch on from the front of the machine there is no longer any power light tested the bulb all ok ?
