Re: turns on and off repeatedly

Try to get to the jumper next to the cmos battery in the mainboard. by changing its position for some seconds while power is off and putting it back , cmos is cleard. start the board hit delete to enter setup and exit saving chages.
ps: if the mainboard bottom was in touch with anything metal from the case then reboots will occure repeatedly and the board might get damaged.

My PC running a Gigabyte GA-M55SLI-S4 motherboard won't boot up - it emits a continuos series of beeps: a 1sec beep with a 10sec pause then keeps repeating & cannot even get into Bios setup

Check your CPU make sure its placed correctly and that you don't have too much contact grease,you only need a very small amount.
If that's not the problem try re-seating your ram and video card.
Other then that look at the power supply could be under powered!
hope this has helped

Try reseating the RAM modules, if it still doesn't work, remove the RAM and test the RAM in another computer or at your friendly computer store.

Please help me to identify my problem

The system beeps when you remove the RAM. This means that POST is working correctly and the motherboard may be fine.

Check that the monitor cable connector that connects to the video card isn't loosely connected.

When you insert the RAM, there's no display. This may mean that the RAM is detected but still faulty. Try using another RAM, if you can. Also remove the Video card (if you have a separate video card). Then, re-insert it firmly, and power up the system once again.

If you don't have a separate video card, you should test the motherboard on the bench, that is outside the computer case. Remove the motherboard, RAM and power supply (and the video card if it's separate). Put it on the bench and power it up as shown here:

You'd need to closely look on the motherboard to see which pins are for the power switch (marked as PW-SW, PWR, PWR-SW, PWR-ON etc). Then, short them with a screw driver, for a second, to turn the system ON.

Replace the RAM and the video card one by one, if the system doesn't give any display even on the bench. This way you can find out what is the problem.

Hope that helps,

M4A785TD-M EVO Motherboard will not boot.


From what you are descrbing it sounds like a PSU issue

Please try the following

1) Remove all the wires from the PC
2) Press and hold the power button in for about 10 seconds (yes i know there is no power :) )
3) Plug everything back in and retry, if it still fails the Power supply will need to be changed

The Power supply can be swapped out at any decent PC repair shop and is quite cheap to do

I hope this helps

Main board won't power up

I would start by removing all of the cards on the mobo, add 1 and reboot, rinse and repeat until you find the bad card, even the ram which I would start with myself, I have had an agp card do this to me.
Like to know where the click is coming from. When you say the power supply is fine, how can you be sure? May fail under a load. Not the only solution to be sure, but a good place to start.

Ga-k8vt800m motherboard specs..

First, remove all power from motherboard, including the Power Supply ATX plug. Then remove ram and all PCI and PCI-E / AGP (Video) cards even network cards... Let it sit for about 5 minutes and then plug in the necessities: RAM, Video Cards and if nothing works repeat the process but alternating ram slots and ram.

Motherboard problem

start troubleshooting by unplugging everything from motherboard, leaving only power supply, motherboard, cpu, memory. also check make sure cpu fan/ heatsink assembly is attached securely and if encounter no problem booting like this, add harddrive, repeat, then add optical drive, repeat.
also when you check hardware monitor, what do u get for readings, i.e. temp and voltage?
