<Assistance Required> Desktop cannot power on

[snowydust]

Happy new year! Unfortunately the pc died again, I didn't turn on yesterday and today I tried and it just can't start (no power yet again)

It was working nicely for 2 days on Fri night and Saturday.

Time for a complete new build, else hard to move forward in 2023 without issue.

Sigh... I thought I managed to rescue my pc, looks like I may really need to get a new build... Really have no idea what's wrong here, now everything like back to square one, same observation as before I sent the mboard and psu to Corbell

I thought it was the end of the episode when your PC worked but its back for a second season.
Hard to diagnose an intermittent issue like this.
Justified getting a new PC then. If not, PSU and MB would be the first to try replacing.

Yea man, i thought so too. Hence i am shortlisting some stuff now by going through the forum, if the pc is unable to power on again, i will probably head down to SLS this weekend already. Once i am done shortlisting, will share the items for you guys to advise, thanks!

1) PSU
or
2) MOBO

The usual suspects

Hi there, in case u missed my earlier posts, i brought my mobo and psu down to Corbell, they tested no issue and i brought back to test components by components (GPU, HDD, Casing) all pass the test 3 days ago, so i was quite sure the issue is gone since i was able to turn on for 2 days straight without any issue. Unfortunately it isn't. I got a feeling it is the mobo that is behaving eccentric, so since i am using B360 series mobo, i think it may probably make sense to upgrade to a new rig

Maybe you can visual check your motherboard any burning capacitor and it's not so difficult. This could help to narrow down which component to replace or else change new set of PC lor. Sometime burning capacitor might not lead to total damage which might explain sometime can boot.

Welcome to the Club of hardware trouble shooting.
Can work sometimes doesn't mean can work all the time.

1) Try using another PSU.
If cannot work then most likely your MOBO.

Done, also got Corbell to check as well, so definitely nothing looks out of place visually~

Ya, this could be an option, which means that I buy a new PSU first and try to see if the issue persists; if no issue, i can keep the new PSU and send the existing one for RMA; if the issue persists, i can use it for the new rig (this is a time consuming process though, will prefer to settle everything at 1 go)

Then you jitao buy new
MOBO + CPU
Your CPU is old liao anyway.

Even Ryzen 3600 is faster than your 8700.

interesting case here, all tested and worked for 2 days then back to square one... chances really could be mobo or psu... yup maybe u can consider to upgrade if your budget fits... 2days ago i was at SLS the guy play MW2 until his mobo died too it was a either a 3 series or 4 series mobo out of warranty...

Yup, will monitor my pc for the rest of the week if the issue resurfaces again. One thing i notice is that the Windows time seems to be out of sync rather frequently despite I just replaced the CMOS battery and also configure the Windows Time service.

If u so comfortable that the PC parts are all working n tested by third party. U need to check ur casing reset or Power switch. It maybe the power switch is stuck. N still not able to ON/off ur mb.

Also assume ur casing SW is stuck closed. To MB this mean a long hold of power SW mean a force OFF. Frequently force OFF to mb will screw up the bios timing etc due to interruptive forced power off.

Another way is to disconnect ur casing power switch. N turn on just using ur paper clip for a few days to see the issue still persist...

Doesn't seem to have issue with the power switch

I have removed and re-inserted the JFP side of things

This one... When it works, everything runs fine. The next day, the entire pc may not power on or delay powered on... Even if i tried to short the power switch pins on the mobo, nothing responds.

I have also just flashed the bios to the latest, will see if the pc dies on me again...

If that e case, I think your idea of getting a new PSU first to try is the way to go forward. Hopefully bios update help.

First of all, I just want to say.....you really hand itchy. Lol.
If it ain't broke, dun fixed it. My previous PC set with the infamous Biostar mobo lasted a good 10+ years before suddenly died. I stick to the mantra of "no meddling with the system". Inside dusty or fans dusty, so be it.

Anyway, thats me. Age caught up w me and I really dun have spare time to do those trouble shooting....
Can be a pain in the arse.

Reading thru all your post, i strongly suspect it is your mobo. As evident by the CMOS timing out of sync.
It should mean something.

But as Entry Level PC had pointed out, since you want to settle everything at one go....get a complete new system.
Include getting a new casing. (which will also elimate any casing switch issues as pointed out by ranma21.)
Although quite rare occurence. But things happened.

Btw, Happy New Year!!

Happy New Year too!

Sometimes intention is good but the result is terrible very unfortunately; i should just let it be dusty; this will probably be the way going forward Probably experts here can advise me how to clean desktop properly will be highly appreciated!

I highly suspect it is the mobo too, but replacing the mobo is as good as getting a new rig. Although i am not keen in getting a new rig (both time and cost), i think short term pain better than long term pain, just do it once for all and next time don't anyhow "touch" my internal pc anymore

If you know how to DIY, it's a fun hobby and can slowly enjoy the process but usually I complete it within a day include install OS. I had DIY my own few sets and last time don't even have YouTube to guide.
