When you reinstalled Windows, did you use an HP OEM version? NO?

Did you bother to save off the HP drivers so you could reload them later? NO?

You said you updated the drivers, did you get these from HP? NO?

The HP proprietary drivers are NOT provided when you do a Windows reinstall from media you downloaded or created.  These drivers are critical to the hardware functioning properly -- and without them, there is no guarantee that the laptop will work properly.

You said there is a blinking cursor -- is this all that is showing on the screen?

This issue is often due to a failing drive.

So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the HDD (Hard Disk Drive): http://support.hp.com/us-en/document/c00439024

If not, to check the HDD you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.

If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.

Please note that if your model has an SSD instead of an HDD, these diagnostics might not work properly.
