i have a dell laptop machine.. it fell down and my key board got problems, so i decided to dismantle the machine and wash the motherboard with water and so i did, luckly, i got my key board working again... but from that time, when ever i shutdown the machine for some good time let it be 30 minutes, especially when i power it for during night. it refuses to power on all the components (fan, ROM,Screen i.e. ALL) except the power LED light (only)......
it does this for most of the times, but some times, it powers on successfully, but rarely..

i appreciate any help. thank you
