mobo or psu?
I've searched through threads and couldn't find a clear diagnosis. Anyways I woke up one morning about a week ago to find that my pc won't start. I switched off the psu and then back on and didnt get it going til after a few repeated attempts. One of two things happen when I try get it started though; 1, the pc fans spin for a few seconds and dies but psu, hds, and mouse are running or 2, the pc fans run really fast and psu, hds, and mouse are running also. Days go by and it takes longer to get my pc to fire up until a few days ago where I couldn't get it going at all.
No forced shutdowns no bsod. Tested all my ram sticks and each slot, tested gpu with onboard grapics gpu, tested psu on another less demanding rig and it booted properly. I then tested the bare mobo and I notice that I get the same beep with everything in it. With various components, its still the same single short beep.
