[HELP] PC won't POST and it just keeps on "restarting"

[adulaamin]

Good day! I took it all apart and set up the parts outside the case to try and boot it up. I placed the mobo on top of its box and I also updated the BIOS through the ROG Connect usb port. I waited 30min and also double checked no LEDs were blinking before removing the flash drive and before booting it up. Nothing still happens.

I was able to borrow an ax850 and an asrock z77 extreme 6 board. I plugged the processor on this board and used 1 stick of RAM. I plugged everything up and switched it on. Nothing displays on the monitor and the Dr. Debug LEDs show 00. Now based on the user manual, 00 means not used.

does it display 00 when the cpu is not installed and powerd on ?

 

[adulaamin]

Let me check... give me a min or two...

Edit:
It won't turn on without the processor...

 

[Jetster]

Did you use the same memory? Ive never had a CPU go south. I know they can but its rare.

 

[Shambles1980]

if your processor was in the board that said 00 but it wont power on without processor then processor is probably fine. some msi board had an issue like that with some processors. Could be something to do with the microcode in the bios but i dunno what the cause was had to rma a msi for that and the cpu was fine. (im using the cpu now so it is fine)

not to sure whats up other than that though. can you borrow some ram?

 

[adulaamin]

I used 4 different sticks of the RAM I have. Tested them one at a time on each mem slot. Could it be that all 4 are dead or the processor or RAM died when the M5G died?

 

[Shambles1980]

you may also need to test with a different psu. extreme ripple/low voltage could cause issues.
and could help explain the errors yu were getting to start it

 

[rtwjunkie]

i think he said he borrowed an ax850, and its still not working right with that and a different motherboard. The only constant i see is the cpu.

 

[adulaamin]

Ya I think I need to borrow a diff processor to test both boards... time to call some friends and force them to stop playing for a few hours I guess...

 

[Shambles1980]

same here. but i dont see why the board would display 00 with a dead cpu and not turn on at all without a cpu.. if it wont turn on without a cpu it should not turn on with a dead cpu. "was why i asked to check"

I ever experienced 3 of 4 rams dead at the same time, if you could you may borrow from your friend and test it again

00 on Asrock boards means cpu problem. See this page for debug codes. I hope you correctly installed the cpu and connected the 8-pin power connector and the 24-pin power connector from the psu to the motherboard. If you did, then either the cpu is dead, or you need to try with another (preferebly non-Asrock) motherboard, since the Asrock boards are plagued with this particular problem. What code was the Asus motherboard showing when trying to start directly in the UEFI through that particular RED button in the motherboard? You haven't answered if you tried to do that.

 

[adulaamin]

I think I can 100% confirm now that both the motherboard and CPU are dead. My friend's here and we tested the processor using 2 different boards and the M5G with a different processor. We also used 3 different PSUs. All the RAMs though are working also the GPU. I don't know what could've caused this.

 

[Nabarun]

I'm very sorry to hear that. But seems very unlikely that both the motherboard and CPU would die at the same time. Have you checked the motherboard's cpu socket very closely? Are all the pins intact? Also, keep in mind that when you put the cpu to a new motherboard, you need to go to the BIOS/UEFI and reset the BIOS and save it. But I understand it is difficult when there's no display. You may have a dead cpu, but you still havent answered what the ON-BOARD debug LED shows on the ASUS board when installed with a new cpu. Also, I hope you're using the onboard graphics and NOT the GPU. Do keep us updated.

 

[adulaamin]

The asus board won't show anything on the debug LED. It won't power up. We did reset the CMOS on both the other motherboards we tested the 3770k with. We also used 3 diff PSUs.

This may sound annoying, but did you connect the 8-pin and 24-pin connectors and make sure that the psu was ON (there may be a switch on the back of the psu)? You did mention in the beginning that the pc was restarting. Is that still happening now or no response at all? I'm assuming that you are using your motherboard's built-in start switch and not connected the cabinet's front panel headers to the board (don't). Just still hoping the board isn't dead

 

[adulaamin]

Yup we made sure that all the cables were plugged in properly. What happens with the M5G is the LEDs just light up when you switch it on. The debug LEDs show nothing though and the CPU fan doesn't spin either. Oh and I tried using the Start switch and I tried jumping the power pins.

We used an intel core i3 ivy bridge processor and 3 PSUs an AX650, AX850, and an FSP Aurum 1200w. We used 2 other boards, an Asrock Z77 Extreme 6 and an Asrock Z68 Fatality. Both of those boards have the latest bios and worked flawlessly with an i5 3570k. The PSUs, RAM, and video card also worked on those boards. We did reset the bios on both as well before we plugged my 3770k. We also tried the working processor on the M5G and same thing happens, nothing.

I really don't think were doing anything wrong with plugging the cables or any other parts.

Well, then the board does seem to have problems. You should contact Asus now. Do you have a surge protector?

 

[adulaamin]

Yup I'm using an OptiUPS 1500B. I'll contact ASUS asap. Although based from what I've been reading on local websites/forums here in the Philippines, it seems it's gonna be a PITA. I won't know until I try so I hope it's gonna be OK.

Has anyone tried sending a bad chip to Intel btw? Is there something that I need to know?

 

[Aquinus]

Generally speaking RMAs for most companies go pretty well for me, but I have no idea what kind of experience you're going to get outside of the US of A. That's interesting that the LEDs just read out 00. I would expect it to hang on CPU initialization if that were the case. Maybe it's bricked really bad? The CPU doesn't have anything on the contact-side that would create a short, would you? Like conductive thermal compound?

 

[adulaamin]

I checked for that too. And bent pins as well. The socket is clean, so is the processor. Upon closer inspection I found something interesting on the top left corner of the motherboard near the clear CMOS button and on the back area of it as well. I'm trying to upload a pic of it now through TPU. I'll post it ASAP.

Pic:

 

[Aquinus]

I can't tell from the picture. It looks like smudged dust to me. I don't know what to say.

 

[jsfitz54]

The dust colored area should clean up with this: http://www.fcpeuro.com/products/crc...-11-oz-05103?gclid=CP6h6eXC978CFSgV7AodmQ4AgQ

Alcohol based cleaner should remove residue. I have sprayed entire boards with it. I had a Dell monitor that was not coming on so I removed the entire logic/power board and sprayed off all the accumulated greasy dust and inspected the caps. It works now.

 

[adulaamin]

How about the solder points which has something like a line conecting them together? Could that have caused a short? The pic got resized by photobucket its pixelated when you try to zoom in. Tried uploading it through TPU but constantly got errors. Might be because Im using a phone. The residue is white-yellowish in color. Now Im thinking something spilled on it...

 

[jsfitz54]

That area looks like it was overheated. A spill could cause stray current to travel out of bounds. The lines are the copper circuit board embedded between/underneath the black coating. There may be a component that has gone bad, look for cracked solder points, due to heat stress.
