PC won't turn on

[TeethOfMidas]

resetting bios is low risk (unless it has been flashed to support newer CPU), it just go back to factory default
.
I am having the same problem with a 9 month old Gigabyte B450M Aorus M. Tried 3 PSU , each time after new PSU it will work for a few days/weeks before refusing to boot again.

I gave up and just ordered a new mobo online, now awaiting delivery

My worry is about having to re-configure the BIOS settings after the reset, because the setup was done by the shop back then when I purchased it from them. Tried googling on that part but it mainly shows how to access BIOS instead of configuring.

I've just tried. Only the motherboard is connected, powered up pressed ON and same thing nothing happens. No fan no lights no sound of anything running. Can I assume if POST did run, there would be something audible (since there's no monitor connected, I can't determine on-screen)?

Wah, one of my old PC casing is like that, no matter what I do, the PSU fans just doesn't spin.

Then go pay $50 to $100 and ask ppl to troubleshoot. 3 pages of thread and you still dont know what is wrong with your computer, dont waste time here and everyone’s time.
These are the most basic steps to troubleshoot and you dont dare to do. How are u going to find out what is wrong and why bother to ask us.
How can resetting a bios is worse than non boot, you sound like a woman to me.
All Motherboard come with default bio setting and they boot so resetting the bios do more good than harm.
What is the use of putting ram on the motherboard and tell me you cant boot. So u expect me to know ram or mb is spoilt which how am I suppose to know.

Relax man, no need to get riled up.
If not for the ** period, I would've sent it to the shop for troubleshooting. We are 1 whole month away from lifting of the **, so here I am with the hopes I could do some tests within my means and eliminating some of the possibilities.
I'm also taking this opportunity to maybe learn how to troubleshoot a PC when something goes wrong, and if some of the tests seems out of my level, I think it's understandable I do it only if I know I can manage the after of doing the test.

Like I've mentioned a couple times earlier, I am unfamiliar with this. Not everybody sees this tests as 'basic' as much as they are to you guys who are experienced in it. That is why I'm asking for help and opinions here, if I can do everything with no worries I wouldn't need to post for help.

I also mentioned, that my worry was with re-configuring the BIOS settings after the reset, not so much on the actual reset.
"What if I do the reset, it works and boots up, and then I get stuck at the BIOS page?", that is my worry.

Anyway, how is being a woman (not saying I'm one) a factor in this situation?

I apologise if my replies offended you somehow, but I'm just trying to self-help and learn along the way. Thank you for your suggestions still, I appreciate them.

Peace!

Let me enlighten you on the BIOS RESET everyone is talking about.

Doing a BIOS reset basically means setting everything to minimal (no tweaks for performance whatsoever). If you can get the PC to POST (Power On Self Test) after that you can run with the defaults with the exception of maybe changing the boot order (IF you have more than 1 HDD).

Hope this helps to clarify the test here.

Repair shops in SLS are still open, u can make appointment and go down without issue as it is an essential service. No need to wait after **.

The first step to troubleshoot is do boot with motherboard only and reset the bios.

"What if I do the reset, it works and boots up, and then I get stuck at the BIOS page?", that is my worry.----> Is this worse than not able to even boot? Totally don't understand the logic behind this.
Not able to boot, you definitely have to pay $$ to get ppl to diagnose. If you are able to boot and the bios cock up, you still have chance of changing the setting and learn.

Resetting bios will not cause u stuck at bios and there is nothing to configure in the bios setting.
The person who set up your desktop did no configuration as default setting is good enough to boot.

The only issue is when u have multiple HDDs and the first boot is not the window HDD thus boot error. Simple solution is just connect the HDD with window.

Your mb likely dead.

Thank you for the clarification! This part addresses my worry!

Sadly the shop at that I normally go to at SLS isn't, maybe because they are mainly into retail of parts.

I wasn't around when they setup my PC for me, so I had zero idea if there were many configurations to be done at the BIOS page, that was why it was worrying for me. The 'getting stuck' at BIOS part would be because of my lack of skill/knowledge, not so much on causing system to hang.

Thanks again for your clarifications, I'll give that a try and update here!

Your mb likely dead.

Maybe, so I might have to prepare for a new PC in case it really is the MoBo.
But so far seems like it's still fair chance between PSU & MoBo.

 

[jq75]

If I'm hesitant on resetting the BIOS at this point of time, could I try out Situation 2's suggestion? As of the last test I did, none of the fans moved. But that was with the PSU connected to MoBo, and MoBo had both RAMs onboard.

Btw I think the Power button should be okay, because when I press ON the BT adaptor light comes on. It's the only indicator that reacts everytime I press the power.

Remove bt adaptor if possible while troubleshooting

MSI b450 gaming plus



you are right,
I confused reset with flash this ** is giving me brain damage

New mb, u need to format HDD and set up everything again right?

 

[jq75]

First disconnect everything except power to motherboard. Take out all rams and graphic card.
Power on using screwdriver method instead of using casing button to eliminate power button spoilt.

Situation 1
Power on to see if the CPU fan spin. If it did not spin, reset Bios (either using the pin method or taking out the battery for 5 mins & all power supply to MB).

After resetting Bios, try booting again. If it did not spin. 50% is MB and 50% is PSU.
After that test the PSU by using the paperclip method to see if the fan spin. If the fan spin, it means the PSU likely is working and 80% your MB spoilt.
Even if the PSU spins, it does not mean it is working 100%. There are chances it is faulty and unable to provide the required amp to its rails.

Situation 2
If the CPU fan spin, it means MB and PSU is working. Shut down and add 1 ram only and test again. If adding ram cause no post, it should be ram spoilt. If you have more than 1 ram, slowly test each individual ram to see which one is spoilt.

If I'm hesitant on resetting the BIOS at this point of time, could I try out Situation 2's suggestion? As of the last test I did, none of the fans moved. But that was with the PSU connected to MoBo, and MoBo had both RAMs onboard.

Btw I think the Power button should be okay, because when I press ON the BT adaptor light comes on. It's the only indicator that reacts everytime I press the power.

Try the method above, re sit the power on cable connector on MB again to make sure
1. BARE board with psu ONLY - update outcome

Other hw, power connectors unplug

I will be using the same B450 chipset, so good chance windows will run without re-installation

see how it goes when the mobo arrives.

Okay, I removed the 2 RAMs, a WiFi adaptor from the MoBo (just noticed it was there), the external BT adaptor and unplugged 3 cables that seemed easy to put back (as below)

I then did a reset of the BIOS by removing the battery for 5mins and reinserting after.

Here's what happened:

- The PSU & Case Fans ALL started spinning, lights of the fans came on as well (Good news?)
- I plugged in the monitor, but nothing was displayed (my monitor showed "no input detected")
- Also I noticed the everything would turn off after 21secs, and then restart again after 3 secs.
(I timed this a couple of times, this 'cycle' carried on consistently.)

Then, I long-pressed on the Power button to switch it off. Added 1 RAM back, and turned on.
It could turn on, no problem. So I shut down and added the 2nd RAM back in too. Again, turned on with no problem, but with some differences:

- The auto-restart cycle stopped, it doesn't turn off after 21secs anymore.
- When I plugged in the monitor this time, it could detect the monitor and it displayed "BIOS has been reset, please re-config your BIOS setup items if needed"

What do I do next? Connect my KB+Mouse first to enter/navigate the BIOS "OK" option?

OR add back the WiFi adaptor first, try again to see if it can turn on, before connecting the KB+mouse?

At which point should/could I start to add the SSD/HDD?

Great news! Looks like there is still life in your system.

Start reconnecting one item at a time and testing until u can figure out what is causing the problem. Once it starts to act up again u should know what’s failing

Good. There's some progress

Reset CMOS on bare system shows some results

This is what I usually do,
If can't manage bios, just load default settings (to be safe). Check date time if they reflect current time
KB & Mouse connected

Reset few times to ensure they respond the same

While plug / unplug ram, have a soft brush or old tooth brush to clean all connection points, slots from dust.
Then add ram pc by pc, slot by slot. each ram restart system couple times. When all rams are seated in slots, even at times playing around different slots and stable. Then system hdd.

Other extras such as adapters, etc shld be last when system is stable enough

I ever encounter a troubleshooting issue due to ram.

corrupted bios?
faulty ram slot sibo

 

[TeethOfMidas]

Sorry for the long update, wanted to wait a couple hours to confirm before updating the below:

As suggested, I re-connected items one by one and each time restarting the PC to make sure it can still boot up. Turns out by the end of it, I was able to reconnect everything as per how it was before it died on me! Also, when I entered Windows I was actually brought back to the exact page it was set to Sleep the last time (wow). There was something weird at the start though, my KB+Mouse was SUPER laggy and that caused me a lot of delay when navigating through Windows. After about 30mins and a restart, it seemed to return to normal.

I've been running the PC for a couple of hours now and using it as usual, no anomalies detected so far. BUT, I realized that now when I reach the Windows login page it actually shows something about "Bluetooth authentication token" by default, and I have to use the keyboard to navigate to my normal login. Something I'd never encountered before.

While I'm SUPER GLAD that my PC is now up and running, I'm also slightly bugged that I didn't manage to find out which part of my PC might be failing (which caused it to die in the first place), and also the Bluetooth login part

Regardless, thanks a lot guys for your advice here! Really helped a ton!

Thanks for helping with the link!

Not too sure :\ Everything's running fine now with everything reconnected, unable to pinpoint a particular hardware/connection that might've caused the issue in the first place. Only thing I know is different is that I reset the CMOS..
