its your programmer. Build a serial port programmer or use usbasp.

Most of the time, the problem was either a loose connection or dry solder. Check your hardware.

It may be because of loose connection of wires some where..........

one more thing.. always use short cables.. as for different pc length problems comes.. try to connect ur porgrammer to some other pc .. it may wrok

 

[jaksongats]

if there is some problem from parallel port .my os is winxp and motherboard is asus parallel poert is in normal mode ...

 

[incomplete_jerin]

I think that Nikhil just tried to say that reduce the cable length of the parallel port ISP burner & not about the connector in your PC.
