Like the title says, i have a HP Pavillion a6702f desktop pc and it was working totally fine the day when i last used it. But yesterday morning when i started the computer it only loads till the blue menu and it can't seem to load the OS(no error whatsoever) and when I tried to go into one of those menu, the keyboard input doesn't seem to work but I can see the yellow light on the keyboard. I tried to use recovery disk and it seems the computer is reading for few seconds and thats all, no response. Also, i tried unplugging all the cable lines from the CPU and replugging it but its still the same. So yeah i think its some serious damage but i don't know how cz it was working totally fine the last time I used it. So, yeah it'll be highly appreciated if some of you experts can help me out. Troubleshooting performed so far: - Tried booting without any external device - Tried unplugging all the cables and replugging it - Tried resetting the RAM - Tried to boot with recovery disk Thank you.
