Help PC is not working

[MrSweeetness]

Hey guys my PC broke about a month ago the motherboard died, it was a Gigabyte Z77X-UD3H. I returned it to the store i bought it from and skip 3 weeks after I got a new motherboard a completely new one Z77X-UD5H which is really great. and I had about 100€ laying around I changed my PSU as well i got a corsair 80+ gold one whatever not really important right now. THIS saturday I sat down with my friends to build the PC we tried to turn in it on and there was NO video signal and then the PC shuts down itself and restarts and keep on doing this what should I do? before my old Motherboard broke the same thing happened and then the mobo died. Is the CPU dead? and oh yeah one more thing I unplugged the GPU to see if it caused the problem so I did that and plugged the HDMI into the motherboard and it kept doing the same thing I know it's not the GPU fault. Please help me It's has been over a month since I played on PC :(

Are you getting a POST? Are you able to get into BIOS at all? Unplug any drives/cd-rom and try with only a single stick of ram... You may also want to try and reset the BIOS as well, see if that kick starts it.

Nope I can't even get into BIOS all I see is a black screen and the PC making the turning on noises, so should I unplug my HDD and only leave the SSD which is my boot drive on?

Use the motherboard speaker beeping noises to diagnose the problem. What kind of beep code did your computer make? Did you try unplugging all your hdd/ssd/cd drives like Whaler_99 said and seeing if you can get into the bios? Did you try doing a CMOS reset? Maybe try using one stick of ram?

I had a similar problem, look at the cpu socket pins and see if any are slightly bent

@mgsstar wait do you mean the Code that is displayed on the little motherboard display? it's says 15 if that's what you mean

Something I saw from Tom's by a guy named techmayo:

I have the same problem. I fixed it by taking everything out [i.E ram, gpu, sound(if you have one), any usb devices, and the cmos battery] (leave your CPU seated with cooling of course. Then you would use a jumper by the BIOS switch located on the bottom middle of the MOBO[/url=http://www.tomshardware.com/forum/329713-30-mother-board-faulty-debug-code-gigabyte-z77x-ud5h#] and leave it for a good half hour unplugged if you have the patience to wait a day I'm sure it'll work as well.

After you have waited, take jumper out and place CMOS battery back in and try to start it without GPU and RAM to purposely trip a error to see if your MOBO is working correctly. If you hear a beeping from the MOBO speaker then you should be good. Reseat everything and start it up, it should be good. Hope this helps

Make sure you plug in the speaker to see if you are getting any beep codes...

Thanks a lot for the link I'll try it out myself next weekend or earlier if I have the time I hope this works

Something similar happened a while ago when my mate built his with the same motherboard I have which is an MSI Z68A-G43 G3 and I think he didn't plug in the supplemental CPU power or something like that.

I highly doubt the CPU has failed, in 15 years+ of playing with computers I've only ever encounted a single CPU and that was an old Pentium 4 EE which the knob who owned it overclocked it to something like 5GHz and pretty much burnt it out.

Also any idea's what happened to it, I always thought Gigabyte make pretty much the best boards on the market?

It was my fault to be honest I accidently plugged the CPU fan in the wrong place and yeah it smelt like electronics burning shortly after lol

ahh makes sense:)

There has been a problem with some Gigabyte motherboards that if you have the reset switch from the case plugged into the reset pin on the motherboard, it will cause an infinite boot loop. Try unplugging it if you have it plugged in and turn it on.

Assuming this works, should I re-plug the Reset cable again?

I wouldn't. I have a Gigabyte UD4 Z68 board that has this issue, I keep it unplugged and I never use the reset button anyway.

I suggest putting a new cmos battery in each motherboard.  It won't post with there having been power to cmos.
