The front panel looks fine, is there a way to turn of the pc without using the power switch?

This, I have had random no boots before and just needed to cycle the PSU

Also when I dust my pc I use a paintbrush i bought for that purpose only. It works great, just a few quick brushes and a small little blow and im dust free.

You can short the pin header with a paper clip or key on the power switch pins.

Quote:
The power switch on the front of the case is just a momentary contact switch. The motherboard always has a little bit of power, and pushing the contact switch simply completes a circuit between two little prongs on the motherboard that signals the power supply to start supplying full juice to the system. When you open the case and trace the wires from the backside of the on/off switch down to the motherboard, you can pull the those two wires off the motherboard and touch the two prongs with a small screw driver (be careful poking around - touch only the two prongs that were underneath the wires from the switch). The system should come to life. If so, then the switch is bad, it's not making the momentary contact to complete the circuit as it should. Replacing it will be a chore as there are tons of styles and sizes to choose from. But I doubt the switch went bad, so reconnect the wires to the prongs on the motherboard.

Jumper wire between the green wire on the 24 pin header and the other side to a ground (black wire) pin.

Q-tip and rubbing alcohol?

Possibly a sewing needle or something similar to scrape any large globs off.

i would go with this. How much paste do you put on there????? You should never have too much, too little is better than too much paste. If it spilled over the side of the cpu then you should really lower the amount of TIM that you apply.

the cpu might have shorted out since some TIM solutions are conductive.
