Hang in Bios screen few times, then just black screen in monitor now.

Hi everyone, I have setup a AMD 960T with asrock 880GMH/USB3 motherboard for parents around 2 years ago. The computer suddenly cannot get into windows and hang in bios screen yesterday. I could still get into bios setup but with super slow loading speed, but then after rebooting few times, it doesn't even show up anything now with just black screen after turning on the computer now. I have to pressed the power bottom for 5 seconds to turn off the computer.

Is this motherboard fail or it could be something else? Luckily the motherboard is still within warranty, but for the local warranty service, I have to get the board to a location and drop it, then they will check it and tell me what is going on after like a week. So I want to see how you guys think before I go through the process.

check the cmos battery. also completely remove the board and hook it up outside rig to make sure everything is plugged in snug. I would try to check parts in this order:
cmos battery (can test with multimeter)
PSU
HDD/SSD
RAM
GPU
CPU
Motherboard

good luck

How the cmos battery brings down the whole motherboard?

Kind of doubt it would, most bad batteries send you into an endless reboot, but if bios somehow got corrupted it could cause board not to boot. Just seems easiest if you have tester or can borrow from a good PC to check.

sound like the easiest way would be just get the board out and get to the warranty repair center...

thanks!

I just received the board from asrock and they said the board is fine. So is that the problem should be the power supply!? This power supply is a replacement after it had failed around an year ago, last time there wasn't any light or anything running after clicking the power button, so I got a replacement then fine. This time there is power, fan turns on, but blank screen in monitor and seem like harddisk is not running, and no sound from motherboard.

I had an official check for the power supply and no problem, no idea what could be real problem

make sure you check the board outside your case just in case board is warped or something. unplug everything and just use what you need to get it up and running (no dvd drive, card readers, extra HDDs, etc.)

also make sure you clear the cmos

I brought my whole computer to the official support office. After they saw my problem, pull the whole board out of the case and pull the cpu out, then somehow it works after re plugin the cpu. The support staff said it should be because the cpu was not "press down" enough. He tried with my power supply and it can go into bios, then I felt fine and brought back home.

Guess what? It doesn't work at home! Same problem again! I tried and replug in the cpu and make sure every step is correct, tried two different monitors, same problem, never even have stuff on screen one single time.

It wasn't my parent home so I had to leave, finally I unplug everything except the cpu, ram, board, power supply and the case, but the same problem happen. I didn't have time to pull out of the case.

So can that be the case? I will go back to there in weekend to test.

Maybe the case or one of the board standoffs are bad/warped.. I had luck with loosening a screw to get rid of the problem I had. My suggestion would be to go to each screw and loosen one at a time, not completely out, just loose. Each time you loosen another one you can tighten the one before. Remember they don't have to be tighten all the way down, just snug enough to hold board in. As side note, check the heatsink clips, make sure they can't be touched/pressed on when you push on the outside of the case. This could cause bad or uneven contact with CPU- though only think I've seen Intel CPUs with clips on bottom of the board. Are any of your PSU wires running behind board?

Yeah the screw could be the problem, I will try it out over weekend. Actually I don't know how screw and case can make the motherboard just stop working.

It's hard to imagine someone actually stating the 'CPU wasn't pressed down enough' :rolleyes:considering the amount of force into the socket it gets when a heatsink is applied. If that were the case the pins would have been trashed/bent but they weren't nor the socket damaged. Goodness!

From what it seems, the common situation is that the board was removed from the case when it worked. I would check all the cable connections and change the slots the ram is in. It sounds like something got nudged just enough to work there, but from hauling it around after that 'something' got nudged back out of place again. Blue dragon basically summed up the rest of my thoughts at this point.

usually wouldn't, but I had RAM problems with my MB that turned out to be a slight warp in the board that was fixed by a single screw. I'm now getting strange cpu temp readings that come out of nowhere and disappear when I reboot. it says my cores are running at 255C and it throttles my CPU down to 1.4Ghz instead of the 4.9Ghz it should be running at. if it was my CPU package sensor going bad then it might shut down my computer for safety reasons instead of the throttling. I would think it would give you some kind of warning if it was stopping itself from booting, but it might be trying to beep a warning code at you if you don't have a motherboard speaker hooked up.

other than that, it could possibly be the power source. if plugged into a strip with lots of other high juice sucking machines than it might not be able to pull enough from the wall. kinda straining here, but it would be easy to check by plugging in directly to wall outlet as long as you don't leave it that way...

best to try and think what all the repair shop did or used. did they boot up the pc without any of your devices, etc? I've heard strange stories about external usb dvd drives causing booting problems or loss of sound... just strange stuff in general. try to replicate whatever they did at the shop. could be a short in your dvd drive causing the PSU to refuse to power up or something else that we aren't thinking of. if they used different mouse and keyboard, try that if it's something you can do easily. anything and everything that could have been changed needs to be looked at. even a bumpy ride home might have shook a cable lose...

yes it could be the screws or something related to case or even cables. I will get the board out try it with minimum hardware and outside the case in this weekend.

Thanks for your advice. I think I should be able to boot it up if the official repair person can do so.

Those are normally wired with a 10 pin connetor (or 9 for keying purposes), so shouldn't be any issue with that unless a wire is shorted in some respect. For reference, each of the two rows on the connector correspond to one of the USB sockets.

so I just tried:
- move the motherboard out of the case and put on plastic sheet, only cpu, motherboard, ram, power supply, and usb mouse+keyboard receiver.
- no screw
- plug out cpu, ram, power cables of cpu, motherboard and re plug in again
- usb keyboard and mouse with any usb port behind the board

still doesn't work, power on then blank screen

PS2 keyboard is the only thing I cannot try since I don't have one at that home. I will bring a PS2 keyboard to there in next week.
