Question No signal

[Marz74]

No signal. Hi peeps. Wee problem when I installed some new(to me) parts to a new case .lt all worked on the bench. But when I installed parts into case, it wouldn't power on. Fiddled with power switch dupont cable (connected to wrong pin). Now it powers on gpu and other fans turn, but no signal to tv or monitor. Did notice that power supply spins for 10 15 secs then stops. Tried different hdmis

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, used, refurbished)?

Disk drive(s): make, model, capacity, how full?

Also check for objects protruding in back ports or extra mounting points/standoffs under the motherboard itself.
