thank you for your time in advance.
I've recently had to replace my HDD in my computer. I reinstalled another HDD from another computer that I knew worked (OS already installed [Windows 7]) and since then when I turn It on there's no response from the monitor but the Mobo lights up, all the fans are on but no bios boot.
graphics card: Radeon had 5670
OS: Windows 7
if there is any other information you need provided to help me diagnose the problem just ask ! Thank you for your time and sorry I'm not all that tech-savvy.
