Mother board and hard disc arent working properly together

[piipecek]

Hey, after 2 weeks of holidays i came to my optiplex 755 desktop computer and it didn't boot up.

I did some research and made some observations in bios:
Removed floppy disc from the bootup sequence (i dont have floppy reader) and it says onboard sata hard disc (not present).

So I went into the case, disconnected and reconected the sata cable to hdd and motherboard, no change. Then I tried another sata cable (originally from cd rom to motherboard) and didn't work either.

My motherboard has 2 sata ports - 0 and 1 and neither of them makes a diference. How to continue? Thanks

Have you tried a different SATA power connector?

Do you have a spare HDD to check if that one works with the pc?

How old is this system?

I tried both sata connector that exist on my motherboard. None of them gave any other output than the same starting one. I have some hdds over at my uncle's house, as well as hdd reader. I might check those. It's windows 10, but it is on the hdd thats unreadable. Any further help?

I would suggest trying another SATA storage device to see if your original HDD may of just died or not.
