I can't turn on my computer

[Clothik]

When I turn on my computer, I hear 3 long beep sound and then 4 short beep sound. I saw blue screen 3FO. So I tried Memory Test but failed. Failure Id is GLLEXO-9ASBAF-GXPS3F-619NO3.

hi

you seem to have several problems
the error code indicates

Hard Disk 1 Full Test Failure

then the beeps could correspond to this

The red light blinks three times, and then four, short white light blinks (3 long red, 4 short white)

This condition indicates a potential power system failure.

1. Reduce to minimum configuration (CPU, System board, PSU, 1 DIMM of memory), and then isolate the failed component.

2. Reduce further if issue persists.

3. Test your system with a known good PSU.

Contact HP Customer Support for further assistance to replace the component, system board, processor (CPU), or PSU if the issue persists.

This is a macro, recorded answer, read the following carefully, and see according to your own problem.
If you have any doubts, ask me, I will try to answer the best
you have an error message, or a problem with the hard drive (or SSD)
this indicates that your hard drive is certainly damaged
Depending on the error, and its condition, it may fail anytime.
maybe it doesn't work anymore
First of all, you can try to recover personal data

 Once your data has been saved
You can either follow the following or buy a new hard drive directly!
What I am indicating now is just a rescue option
If it works, it will be temporary, back up your data regularly
depending on the hard drive condition, it may work a good time
but the hard drive may fail permanently
it is mainly in order to be able to use the computer, the time to replace the system disk
be careful because the goal is to erase the hard drive, your unsaved data will be lost
so you have to reinstall the computer completely
There are several methods, depending on the installed windows system and your computer

Try a full reinstall
