i think my arduino uno is dead...

worked yesterday

now i cant upload anything into it, 5V pin shows 3.85V (with USB and 12V adaptar), the main chip gets kinda hot and the LED doesnt blink at all when i press reset

is the main chip shorted?

It would sound that way.
Normally caused by a short circuit in some way.
