I have a HP Pavilion Sleetbook 14 PC - Core i5 3rd Generation computer. I'm using Windows 8.1 - 64 bit. I was just updating Nvidia from windows updates but it was taking so long so I stop downloading the updates. Then I restarted my laptop and now it is taking so long to appera login screen. First, the cursor spins for 2 to 3 minutes and then login screen appears with weird characters instead of text.
I tried to install a fresh copy of Windows 8 as well as Windows 7 but it is giving me checking media fail error. (My laptop has no built-in DVD Rom. I'm using a USB portable DVD Rom and it is working).
When I enables the Secure Boot option from BIOS, the screen appers with a message "Boot device not found. Please install an OS on your hard drive. Hard Disk - (3F0). Then I performed Hard Drive test and it was okaye with HDD. I also performed memory test and it was alright with Memory.
But my problems are still existing.
- Taking so long to start up and weird charcter on login screen.
- Checking media fail while installing OS.
