My HP STREAM won't boot and the caps lock key is blinking

Nu? So? What's the solution already.

If the CapsLock key is blinking or there is beeping, read this HP information on the likely cause of the hardware failure based on the blinking or beeping patters.

For laptops, this HP thread describes the different blink and beep codes: https://support.hp.com/us-en/document/c01732674?jumpid=reg_r1002_usen_c-001_title_r0001

To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.
