I got 2 PCs, one of them shows and do nothing when I push the power button. The error first started to freezing the PC and by restarting the issue was solved, but lately the PC wont restart and I got the Restart led and CD Drive led blinking. Now even the leds has gone.
I've put the RAM, HDD, CD Drive and even the power supply on the other PC (the one that stills works) and they look fine, no errors found no wierd sounds.

Re: PC wont start up, No single led is on.
If the components test fine in another pc then it is the motherboard that has went bad. You can try to find the same type as a replacement if you want to salvage the CPU, RAM, etc., but it may be more feasible in the long run to buy a barebones kit and just use your optical drive out of your old pc. Problem would be solved and you would have newer technology. Hope this helps.
It might also be the motherboard. that has a problem, have you ever replaced the cmos battery? You can't mess up your motherboard, if you don't really know what your doing, you have to be every careful, with the motherboard. I recommend that you buy a cmosbattery, I can't promise you that is the problem, but it sounds like it. It might also be a transformer that died. THE MOTHERBOARD IS A VERY DELICATE AND AMAZING PIESE OF EQUIPMENT.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage.
CHECK THERMAL SHUT OFF THERMOSTAT USUALLY LOCATED ON THE BLOWER. for OHMS or resistance with a meter. Should show a closed circuit. Ohms WHEN THIS FUSE BLOWS IT WILL SHUT DOWN EVERYTHING.
NEXT Test the PUSH start switch with meter for OHMS. Should show OHMS when pushed in or on start, and no ohms or infinity when in off position.
If you hear a humming/clicking sound from motor area you more than likely have a bad motor.
Try this test out to see if u have weak windings or relay/capacitor on motor.
Open the dryer door and turn by hand the drum while machine is on ON position. And you or someone else presses the door engagement switch in. If it starts up then u have bad windings
Another thing to check is the belt safety switch. With a multi meter.
Especially if u just replaced the belt. The belt safety switch is attached to the Tensioner and motor. IT LOOKS LIKE A DOOR SWITCH SOMEWHAT a little black pc of plastic with 2 prongs going into it. Sits at bottom of motor. Under the Tensioner. Attach meter clips to the 2 prongs on switch, Then when the little white push button is pressed in it should show continuity and none when released.
Lastly check ur DOOR SWITCH for continuity with a meter when the button is pushed in the (on/Door closed position,) it may have gone bad.
