Hi all, I hv P4 845 chipset motherboard V 1.0 , there is an I-ball company's sticker on motherboard, but i don't hv any kind of manual for that. Y'day i was cleaning my system with blower and one jumper came out from motherboard, now when i starts the system, it generates continuous beep noice. I tried to fit that jumper in every empty pin slot but situation remains same. At some places (between 2 pci slots) when i put jumper, beep noise is suppressed but there is no display of monitor, also keyboard and mouse not being detected. The motherboard hv SD Ram type slots, i tried every part re-fit but still problem persists. Wt could b the reason? There is no other missing part from motherboard. I replaced battery also, but problem is unsolved. If you hv any kind of idea or blue print of old P4 845 chipset motherboard, pl forward it to the following id: rozi_hotgirl@yahoo.com Also post your comments /suggestions here, thx all for support.
