Make sure that you have AC power at the receptacle that you normally plug your PC into by temporarily plugging in a lamp or other device and verify that it works.
Make sure that the AC power switch on the computer's power supply is in the ON position (some power supplies do not have this switch).
If you have AC power going into the computer's power supply, then either the power supply has failed or a component connected to your motherboard has failed.which is preventing the power supply from turning on.
You need a PC power supply tester in order to further isolate this problem. You will require the services of a PC technician to continue.

Lights right side dont work

Power present does not mean the switch is ok. Remove the leads from the switch and set your volt ohm meter to resistance. Depress the switch and see if you have a reading on your meter. If the meter reads O.L. while depressed, the switch is bad.

Depress clutch turn key dash lights up. No click no nothing

you may have a bad clutch switch which will only allow the car to start with the clutch pedal depressed.it allows power through the switch only with it depressed to start the car so you won`t start the car with it in gear causing an accident.there will be a switch that the clutch pedal pushes against that allows power to flow through it to start the car.there should be power on one side with the key turned on and power on the other side with the clutch depressed.

My brake lights are not working at all. The fuses are not blown

Hi!!
Check the Brake Pedal Position Switch on top of the brake pedal, the Lt Green w/Red stripe wire should always have 12v+, when brake pedal is depressed the Lt Green wire should have 12v+ also, if no power on Lt. Green w/Red wire, check fuse # 2 20A, if no power on Lt. Green wire when pedal depressed, REPLACE Switch, If there is power on both wires when pedal is depressed, check IVD STOP LAMP RELAY on the Aux. Relay Box 1 located at the Left Front of the Engine Compartment.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Would a bad Flasher relay cause the brake lights not to work?

The flasher does not stop the brake lights from working. Check # 18 fuse in fusebox under lower left side of dash. if it's ok, the brake light switch, on the brake pedal arm is next. light green wire with red stripe is hot if fuse 18 is ok. Depress brake pedal, light green with no stripe should have power. if not, replace brake light switch. If light green wire has power with pedal depressed, combination switch under the steering is next. Remove the cover from around the combo switch {under the steering wheel}. depress brake pedal, light green wire should have power. If it does, pedal still depressed, orange with light blue wire & wire with light green & orange should have power. Those 2 wires are brake & rear turn signal wires. { The turn signal switch should be in the middle, not right position or left. while checking for power in the last 2 wires. Good Luck drvolt.

Power switch stutters when depressed. PC will not turn on. Has been happening for more then 4 months. To avoid would leave computer always turned on. Unfortunately a reboot stalled and I had to power off...

Try connecting the reset switch in the place of the power switch. Both of them are push buttons so your only problem is that you have to use ctrl+alt+del for reset.

Trigger safety lock

If safety button won't depress, something is blocking operation inside the handle. If button actually depresses, but nothing happens when power switch is operated, then a bad switch, motor brushes worn or stuck, or internal wiring is broken at some point due to vibration. If it is still under warranty, take advantage of it. Does chain move freely by hand and has proper oiling? Can you hear any humming inside when power switch is depressed? Could be frozen motor bearing or damaged drive assembly. In any case, the housing will need to be removed for further inspection if you are going to do the work on this.
