Hello @Alopoki 

Welcome to the HP Support Community.

• Could you post your full HP product model and its product number ? Here is an article explaining how to find this information >> http://support.hp.com/us-en/document/c00033108

• Could you clarify - your memory test failed because your PC lost power during normal operation , or
  it failed because there was a power interruption before the mem test completed ?
  
  
• Have you performed any hardware changes or upgrades on this PC after you purchased it ?
• Do you see any error code from the diagnostics ? Can you provide it back to me ?

Looking forward to your reply. Thank you for choosing HP !

Thank you for the swift reply and for all the provided information.

Can you confirm - I guess you haven't run the HP F2 UEFI/BIOS tests but some other memory test ? Am I correct ?

Here is how the F2 test look like >> https://www.youtube.com/watch?v=6JXUp43ahHA

Thanks for quick response @IT_Winsec, I am greatful.

To answer your quiz, yes I have infact the f2 key isn't responding again!

Thank you for your reply.

The root cause is a hardware failure - your memory (RAM chip) module has failed.

You need to open your computer, get the faulty module out and buy a new one of the same type. Currently you should have 2 GB DDR3 RAM, your new one must be the same:

• DDR3
• 2 GB (1x2 GB)
  
  
• same speed/frequency

Your existing one should be one of these - either PC3-10600,DDR3-1333  or  PC3L-12800, DDR3-1600 - DDR3L

Here is some more info >> https://www.computerhope.com/btips/memory.htm

>> https://en.wikipedia.org/wiki/DDR3_SDRAM

You can buy the memory chip from a reputable local tech store,
order it online or check the HP Parts Store >> http://partsurfer.hp.com/

Note that these models are old and one may only be available as a second-hand version.

Once you replace the memory chip, the issue should be resolved. Let me know how it goes

Thanks @IT_Winsec for the info, I opened it and I can see two modules each reading 2GB, should I try running the test again with either one of the modules to see if they are all faulty or just purchase another module!?

[IT_WinSec]

Thank you for the clarification. The information I found for your model states it only has 1 memory chip (1x2GB) but if yours has two, that is good. It is rare that both of the chips have failed at the same time.

In this case, I would recommend you remove one of them, and then repeat the memory test with only 1 chip connected (inside).

Then, do the same for the other memory chip - this way you will see which one is faulty.

• You can throw away the faulty chip and use only the working one.
• Eventually, you might replace the corrupted one with a new one (similar type to the one you have working correctly.)

Let me know how it goes

Thanks so much@IT_Winsec, DDR3 1333 module is faulty  pc3 is good and passed the startup test but still can't open the windows! What am I missing here or is there some settings I need to do?

You are welcome. 😊 Glad to hear that.

• Please, make sure that you have left only the working one that is in good shape - the "bad one" should be out of the PC.

• What exactly is the error message that you get about Windows ? Please, post it back or take a picture and attach it.
  Is it Windows 7 as described initially ?
