no signal.

[Digital X]

Took apart my pc to clean it. Everything is back as it was but I get a no signal message on the monitor.

Reseated GPU
Replugged PCI E cables
Replugged displayport cable. Tried vga on motherboard no dice.

System powers on and stays, gpu fans, cpu fan and drives etc.

Something simple but it is baffling me..

Held power button on for 30 secs as id seen suggested but nothing.

On mobile.

I figured it out, strangely I rearranged the sata data cables.. after it mentioned a boot device when I tried a HDMI lead.

Got proper worried but thanks for the help anyway
