SOURCE: Start up Probelms HP Pavilion Slimline
I'm the same guest from before and I've got my slimline back up and running. I found the solution somewhere else, can't remember where as I was on someone else's computer, but suggested a boot up problem with some USB devices. One suggestion was to power the computer down, unplug all USB devices and power it up again. The only USB device I had was an HP all-in-one printer/scanner. I unplugged that and the computer booted right up. Hope this helps!!

If the component with the blinking green light is on your network card, it has nothing to do with your problem, but does demonstrate that *********** board is NOT fried or there would be no voltage available to make the light blink.
Something on your board may be fried, but not the entire board.
Unit needs board level service, so obtain an RMA, if available and submit the unit for bench testing and service.
SOURCE: cpu says no input vga signal, then goes to sleep
The no input VGA signal just means that the monitor is not receiving anything from the graphic card on the tower. Is the card a digital (DVI) output card? You'll know by the connector, it's white and slightly wider than a standard VGA connector. If so, perhaps the monitor is set to the wrong input?
If that isn't the case, and the computer is using an on-board or built-in graphics controller, you could try resetting the system's CMOS settings by setting the clear-settings jumper on the system board, or simply remove the plug and CMOS battery for a few minutes. Check the computer's documentation on the exact steps to do this.
Hope this helps!
SOURCE: how do I fix the error no vga input signal no dvi input signal monitor going to sleep
Check if you VGA is properly settled in the PCI slot. Try to take it out, clean the slot for dust.
If that doesn't help, it is well possible that you VGA is not working any more.

There is no signal coming from your PC.
excuse some of the solutions as sounding dumb, but we have to explore all possibilities.
Check the power cable going into the computer
Check the power input disconnect switch on the back of the power supply and make sure it is on
If the pc is plugged into a power bar, make sure it is turned on and the breaker isn't tripped
press power on the PC and make sure the lights are coming on.
now for the solutions that may actually help.
disconnect the power from the PC
if the video is on a card, remove and re-seat the video card
hook the power back up, connect the monitor and try again.
the CMOS on the computer may need to be reset.
I hate totally clearing the CMOS, so what I usually do is remove 1 stick of ram and power up. If the system is alive again, power down, put the RAM back in and power back up.
If that doesn't work, turn the system off, put the CMOS jumper to the CLEAR position for 15 seconds, put it back to the Normal position and then power back up.
Basically, if the monitor works on your friends system but not on yours, the the problem is your system, not the monitor (assuming it isn't working fine til it gets into windows...if that's the problem, you have a driver or configuration problem)
