Just installed new power supply, turned on and my monitor stayed blank. All fans are spinning harddrive purring and graphics card fan spinning. Thought it might be the monitor but after leaving it for 1 hour and the mouse and keyboard lights not coming on seems the processor hasnt kicked in. Thought it may be down to the processor then. Decided to unplug the graphics card out of curiosity, so anyway turns computer back on and it emits a massive beeping sound but.... on comes the processor, mouse keyboard everything. So think its fixed and plug back in the graphics card and what do you know, back to square one again and the processor does nothing blank screen again, whats going on im very confused...

Bleeping sound is just lack of graphics card.Sounds like lack of power to motherboard the PSU should be same size or larger than old one.Are you sure all the required cables are plugged in.
