So I purchased a bricktop from craigslist (HP DV4-2045DX) and after turning it on I found the beep code 1 (CPU not functioning) so after downloading the current BIOS (INSYDE) and extracting the appropriate file, copying it 4 times with different extensions (.fd, .bin, .rom, plain file) I also went ahead and opened the descriptor file and copied and renamed the files (4324, 4325, 4326) then placed all the files on a 8 GB USB formated in FAT32. Started the brick up holding win + B, fn + B, win + esc, fn + esc and same blinking lights.
After pushing all four directional keys at once I get the HP splash screen (No BIOS options or prompt) and windows 7 magically starts up. Once the start up was complete and system was on idle I went ahead and flashed bios from windows. Bios flash was a success. Bricktop shuts down and upon starting it back up... poof dead again.
I removed the USB and tried the directional key method again (with and with out the battery) to no avail. I replaced the usb with out the battery and pressed the directional keys and poof (usb blinks a few times) and hp splash screen windows boots up. I've already pulled the CMOS battery twice but that just showed me BIOS reverted to defaults. I also installed the updated UFEI tools from HP on the hard drive.
I'm scanning with Malwarebytes right and will follow up with combofix, avg antivirus, spybot, and superantispyware to make sure its clean.
I read that using a USB to flash UEFI bios doesn't work anymore that a USB floppy disk drive is needed so I will attempt that method later as well as burning a CD with the BIOS on there since it spools the CD drive before displaying the blink code 1.
I feel like I'm missing something obvious in fixing this. The hard drive is solid so its not a disk drive error.
