I bought a new pc (motherboard,cpu,ram) and tried to reuse my old HDD from my 9 years old pc. I plugged it and when i turn on my pc i have to use the startup repair if i try to start the windows normally it just crashes on windows logo, when i use the startup repair it says it cannot repair the computer automatically.
Please help me, is there any way to fix this or do i have to buy a new HDD?

You have to reinstall Windows, your old install won't just work. Even when "old installs" do work there is usually "fallout" from it. Its always best to do a clean install on a new PC.
