My computer was not detecting a seconday hard drive so I powered down and tried to switch the sata ports. When i powered back on i was left with a no signal message on my tv (hdmi) aswell as my moniter (displayport-hdmi). I left it on for about 15 minutes and it seemed to fix itself but when i powered back down and back on again, the problem happened again but this time its not fixing itself. The hard drive i tried to fix from the beginning used to work fine untill i installed Ubuntu onto it then removed it to install windows 7. As soon as i got rid of ubuntu, i couldnt find my hard drive in disc management or BIOS.
Thank you everyone in advance if youre able to help!
