Motherboard won't boot up

When I boot up my computer, four red led lights come on above the "debug" located in the right hand corner of the motherboard. The computer has power, but won't boot up.

Hey there,

This causes if you havnt connected the power cable coming from th power button to proper jack or pin.

Check out the pin in which ur power button cable is inserted.

Does your system boot when u press the restart or shut down icon from ur windows (OS). If it is not letting ur system to boot then you've been attacked with the Worm viruses. These viruses dont let ur system to boot because they keep their process running untill ur power is off.

Gimme ur acknowladge by rating me.

Thanx.

No debug LED show on my flaming blade gti


If your PSU give wrong voltage it produce same problem with 2 solution:
1-test your PSU
put a wire between green and black and voltage must be:
yellow 12V, red/purple/gray 5V, orange 3.3V.
If your PSU give under voltage (more than -10%):Buy a new one and test your motherboard(mb) with it (in this case there aren't a lot of chance that your mb and/or your CPU are dead)
If your PSU give good voltage:(-10% / +5%):There are a lot of chance that is you mb or CPU
If your PSU give over voltage:Buy a new one and test your motherboard with it (in this case there are a lot of chance that your mb or/and your CPU are dead)

I had a friend transfer my computer components eg. motherboard, HDD, Ram etc, from a ugly computer case to a nice looking one, she got as far as screwing in the motherboard and hooking the HDD...


Hi:
To solve your puzzle, you need to find the manual for your motherboard. If you don't have it still, almost all of them are available online at the manufacturer's support website. The manual always has the pin out diagram for the motherboard, and from there its just a matter of plugging the small connections together. Remember that connections for LED lights have polarity, meaning that they need hooked up one particular direction for the light to work, but any switch connection doesnt matter.

Hope this helps

I have 3 wires on my pc and i dont know where to connect them on my motherbaord - the wires have writen on them "HDD LED" "PWR LED" "PWR S/W" can any1 help me?


Hi Dan,
The wires are from the front panel. HDD LED which causes an led (usually red) light to turn on when the Hard Drive is active. The PWR LED turns on an LED light (usually green) when you turn on your computer. The PWR S/W turns on your computer when you press the on button of your computer. The front panel connector riser is usually located on the bottom right of your computer. They fit on little pins. Unfortunately there is no standard, so connections vary. Sometimes the pins are labeled on the motherboard. . Check your manual. For more info do a google search for "Motherboard front panel connectors". Hank

Their should be a 9 pin header at the bottom right corner of the board. Between the sata headers and the corner. There are two rows of pins in the header, one row has 5 and the other 4. The row with 4 pins has the power switch and the power led pins : : : : . They should be color coded red for the switch and green for the power led. From left to right the first pin is for the led (+) lead, the second pin is for the led(-) lead, the third pin and fourth pin are for the power switch. Also there is a 2 pin header above the 9 pin header that is an alternate power led header, the left pin is (+) and the right is (-). I hope this helps you.

Swapped mother board


Hi Paul,
see page 8 number 15 for location. Than see page 19, System Panel Header in your manual.
The basic wire color's for positive are red, blue, green & can also be light blue, light green, light red.
Negative wires are usually white or black. Case wire colors do vary from case to case.
To see pin one shown on page 19, (positive + for hard drive led = HDLED+). Bottom row farthest pin to the left of set. Pin two is above pin one. Pin two is, PLED+ (known as power led). Pin 3 is to the right of pin one & is HDLED- (Hard drive led, negative). Pin 4 is above pin 3 & is also PLED-, (Negative for power led). ECT!
6781222.jpg If your new case has an internal speaker (Used for P.O.S.T, power on self test). This would connect to, Chassis Speaker Header located on page 8, number 16. Again, normally only two wires are used across the 4-pin connector. (One at each end of the connector).

To see ASRock's main site for the 775VM800 motherboard click this link:

Good luck Paul!

No start up, no bios boot , only "no signal "on screen


Is the CPU fan spinning? if not, check the coolant between the CPU and the cooler (ensure it's not dried up, and replace it if it has or if there is very little there).
