Nothing on monitor, red light on mobo, long beeps

[Guest]

So I took out my motherboard so that I could reapply some thermal paste on my cpu. I took out all the components, unplugged everything, put the paste on, screwed the mobo back in, and put everything back in.

now when i boot up, i get very long beeps (no specific number of beeps, they just repeat with about a half second pause in between) and when i first boot up and go to shut down, a red light comes on on the motherboard right below the CPU fan connector.

Hardware:

Q9450 CPU + Stock heatsink
x2 EVGA 8800GT GPU
nForce 780i SLI board
4GB Corsair dominator RAM


Anyone able to help?

Did you check or mother board manufacture manual to see what the beeps mean???? Usualy certain number of beeps or lengths will mean different things :/ also did you try to clear the cmos, check to make sure the mobo is grounded again ok???? Does it all power up, all fans spin??
