That is not normal.

Other than a USB cable, what is connected to your Uno?

Usually when that hot, an IO pin has been damaged, and it's just a matter of time until the chip dies. Or it's dead already.

Sounds dead.
Does the loopback test work?

Not for a beginner - have to fool around with signature bytes to program them. Once get past that, they are nearly identical.
You have a way to install a bootloader? If not, at least get one bootloaded part to start so you can use the Arduino as a programmer for blank parts.

okay i understand. another shop nearby sells one ass follows "ATmega328 with Arduino Optiboot (Uno)" for quite cheap... it doesnt specify 328P nor the -PU at the end but if its pre loaded could it work? otherwise il go for the one you suggested?
