Can you write down the error you get? We can't say anything until we get the correct error message.

there is no error msg as such bt pc hangs as soon as booting process ends (loads evrything fine) and startup screen of ubuntu donot appear
Same prob occur evrytime and harddisk led keep on glowing

Whats the last thing that loaded ? Did you get any hotplug error.. Read the lines carefully... Errors need not be at the end alone...

First tell me your System configuration - everything. And what error flashes on the
screen? Note it down and post it here.

see in which place ubuntu hangs, in my system, it used to crash when "STARTING HOTPLUG SUBSYSTEM" appeared. i pressed CTRL+C and the task was
skipped. Do the same, ie, press ctrl+c when it appears.
try it

I have this exact same problem; it hangs after everything is loaded, right when the desktop and cursor appear. It did work once after I installed Windows, but then after I rebooted it continued to hang on every attempt. No error messages appear.
I am running a sis755 chipset, athlon64 2800, 1gb ram, and a Hitachi pata 160gb.
