I have an HP Touchsmart 420
Whenever I try to turn it on, it stuck on blue screen showing hp logo and a message "Press the ESC key for Startup Menu" and of course the keyboard ( all keys are inactive)
I think the issue started when I put someone's flash drive. but I took it off
-I tried taking the hard drive and putting it back ( and even I put new one)
-the ram also I took it and put it back
- the f9 and f1o not working
What am I supposed to do pleaseee?
How can I make computer forget that external flash drive ( I do not have it now)
