Question about Biostar M7VIG-400 (M7VIG 400-COMBO4) Motherboard

3 Answers

PC wont start up, No single led is on.

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.

Is there something I can do to save the PC?

Thx in advance.

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.

Check on the back of the switch, the wires may have fallen off, or the switch fell apart.

    What about taking all the wires, ONLY one at a time, and disconnect, then reconnect? Just to be sure it is not a bad wire connection. It probably is the motherboard, but just a shot, you know.

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 cmos battery, 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.

Dryer wont start.


Electric dryer no start does nothing

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.

Lets see if an error code pulls up.

With the machine off, press and hold the Wash Temp Down button and then push the power button until the machine gives 2 short beeps and lights up. Now press the Spin Speed Up button three times so that the Hold and Slow LEDs are illuminated.

The eight wash progress LEDs will show the error code.

Gateway laptop i push power button it wont boot up but leds in front flash 4 times


Try holding down the power button instead of just pushing it. I had this problem with my HP dv7 and holding the power button down for around 5 seconds worked for me. Also make sure that its plugged in to a power source.
