Boots to HP Logo Then Black Screen with Mouse Pointer

[BillAtech]

Hi;

I am trying to fix a Laptop for a work colleague.

It is a HP Pavilion G62210sa with a Windows 8 sticker on it (not sure if it is 32 or 64 bit).

At first it would only power on to a black screen however after cleaning it and removing one of two memory modules (the original was 4GB and somone had added an extra 2GB same type but different brand.

Anyway after removing the memory it now boots, but I getan HP Logo and then a black screen with only a mouse pointer?

I can bet into boot options pressing Esc but when I try the F11 option the screen stays blck for ages but eventually the various test options are available. If I try recovery mode it just stays black.

I tried Safe Mode using Command Prompt and I managed to get to the command prompt option and enter the correct command but when re-booting - same black screen problem.

I don't know what the owner did before this happened?

Any ideas - the Laptop obviously works I just need to reset it?

Thank you for posting on HP Forums,

As I Understand the computer boots to the HP logo and then black screen with the mouse pointer,

Don't worry as I'll be glad to help you, although, to provide an accurate solution, I'll need a few more details to dissect your concern: 

Have you attempted to tap on F11 to access the recovery manager and restore to an earlier time it worked?

Did you attempt to make use of your recovery media since none of the other steps have worked?

Did the issue occur after a recent windows update or bios update?

While you reply, here's something you can do:

Please attempt the below steps:
 

Perform a hard reset

Attempt a BIOS recovery

Run the System Diagnostics tests

I had tried F11 but I seemed to be getting the same problem. Then I found that you could also hit the Esc key for additional options. Manged to try and get into safe mode but still same problem.
Anyway I tried F11 again and then git a black screen but went off to make T.
When I got back the choose a keyboard layout was on screen. It just took ages for it to show.

Anyway I managed to try the Microsoft System Restore which took forever after which it told me that it had failed.

I rebooted and ta da I was met with the Window sLogin screen.

So looks like it MAY be OK.

Thanks
