I have an HP Pavilion dv4 Notebook PC 64-bit and frankly it's not working. Everytime I turn it on it begins to start up like normal, until a minute after I logon. It will reboot and tell me it shut down unexpectedly after flashing a blue screen that I can't read. Luckily I got the screen on picture and found that it had a stop code that read---> stop:0x0000007E(0xFFFFFFFFC00000050xFFFFF800022CFBB40xFFFFFA6016B9B3C80xFFFFFA6016B9ADA0) If anyone can help I'd love and appreciate it greatly! Let me know if you need more information to help solve this. Thank you!
