Components(every component listed is just 5~6 months old)
Motherboard: Gigabyte Aorus Z370 Ultra gaming 2.0(rev1.0)
Processor: 8th gen Core i7-8700(non-k version)
PSU: Corsair CX650M
Ram: corsair vengeance 8GB DDR4 2400 Mhz C16 - single stick
Storage: Samsung 960 Evo 250GB NVMe M.2
Case: Corsair Carbide Spec3
GPU: Onboard intel graphics only
Power: Clean power - APC UPS 1100VA
Two system case fans and I don't OC nor do I run multiple applications at the same time... at most, I'd run Guildwars2 MMORPG but I hardly suspect that's an issue
Scenario1
When I use my PC for less than ~ 30 mins: Everything is fine... turns on properly, shutsdown properly(with windows start->poweroff and the case powerbutton), restarts properly, i can play MMORPG games properly... no lags and no issues everything is perfect
Scenario2
If I use the PC for more than ~ 30 minswithout shutting it down, there are no issues with the operation and I can play games, Browse the internet, watch movies, listen music... no issues, no BSOD, no freeze, no hungups, but when I decide to turn off my PC, the OS shuts down and monitor switches off but the fans and LEDS won't go off. waited for 5 whole minutes... it won't power down... pressing the case power button does nothing... press and hold the power button for 10 seconds does nothing either... Hard power off by pulling the plug is the only way... If I try to power on the PC, the fans and LEDs will start and stop like some kinda morse code signal but won't bootup(no beep)... keeping the PC disconnected from power source... after that, my PC won't POST properly and boot until the next day... the next day this repeats... at this point i'm scared to poweron my PC suspecting some component might go bad beyond repair
Last event that I did before encountering these issues
Updating the Intel graphics drivers(with game booster presets for fortnite, wow,...) with the intel driver assistant software(approximately sep3 2018)
Troubleshooting Performed
1) Updated motherboard chipset drivers followed by intel vga drivers from gigabyte website w..r.t the motherboard
2) Removed and reseated all components connected to Mobo
3) Checked the startup apps(if any) which might be controlling mobo - found nothing there
4) Reset Bios settings to optimized defaults
5) Checked the Ram Frequency in bios settings - no issues there
6) CMOS battery seems fine - date time settings - system clock shows the correct time and bios settings are saved and retained after poweroff - poweron
7) RMA'd the motherboard to Gigabyte(still under warranty) and they reported there are no issues found and the mobo is perfectly functional (though I suspect that... coz the issue is replicated only after ~30mins of usage... I mentioned that explicitly while RMA'ing it)
8) Suspected PSU might allow only power on and not power off when using the case power button - but power on and power off works perfectly when using the case power button when PC usage is less than ~30 mins
9) WakeonLAN, WakeonMouse, WakeonKeyboard is not set
Steps not yet done
Removing the CMOS battery - I'll try this and reset CMOS but I hardly doubt this'd fix the issue
Reflashing the BIOS - since PC operation is perfect within 30 mins, i doubt this'll help. MOBO has the latest BIOS F4... but I'll try this if I'm desperate
Reinstalling Win10 - case powerbutton overrides the OS and the fact that it doesn't POST after hard shutdown, i hardly doubt that OS could be a culprit
MemTest for RAM - heard it'd take more than 6 hrs... and the fact that my PC works perfectly before shutting it down, decided to reduce this step's priority
Haven't checked if the PSU fan is functional
Is there some kind of component that has a possibility of misbehaving after some time of usage(may be due to heat)
Some guy explained in a thread that there's a chip in mobo that controlls the case powerbutton to PSU connection and that could be an issue... but the power button functions properly if usage is less than ~30 mins
Is this due to static electricity? if it is, why not show those symptoms when using it less than ~30 mins
Is it coz of keyboard and mouse shorting something out in the board? if so, how do I confirm?
All these years, I've never encountered or heard of this issue... Plzzzz someone, lead me in the right path... I don't have a spare PSU to test with... If I have to replicate the issue, I need to use the PC for ~30 mins else I can't convince Gigabyte service guys and they'll conclude there's nothing wrong with the board and they'll simply return it to me
Hope this doesn't drag onnn until the warranty expires
