I was getting no signal to my monitor so I put my spare gfx into the second pci slot and it worked. So I ordered a replacement mobo and a new cooler and put my rig back together but again I have no signal to monitor. All the case fans cpu fan and gfx fans spin and there is a light to indicate mobo is on. I tried removing memory but as far as I am aware my motherboard has no speaker. My creative speakers were plugged in but I get no beep with or without memory. I'm worried I damaged cpu when cleaning and moving it. There is no light on keyboard or mouse either.

Please help if you can.
