Check the device manager? Or try to reinstall the driver? It may help.

thz for reply !! i dont thk device manager have it, bcoz it dont even have the pop up USb thing.
how to reinstall the driver, bcoz i didnt install it at the 1st place ?

Look inside the device manager. It should show all connected devices. It there is no driver, then you will see a yellow question mark. If the driver is installed, uninstall it

i tried plug and unplug the programmer while looking at the device manager, nothing pop up. But when i replace UIC00A with UIC00B, it work fine. So, i need to know how to make sure that UIC00A burned ? with the green light still on.
Or did i accidently erase smthg in it ?

The green led is just the power indicator to indicate the 5V. Is there any other activity on the other leds?

I mistakenly supply external and internal supply to my board

How many volts? If its more than 5V, then, most likely its gone.
