Case:nzxt h510
Cpu:ryzen 5600x
Cpu cooler: ID-cooling 240 liquid cooler
Graphics: msi ventus 3x rtx 3060 12gb
Mobo:asrock b550m pro4
Ram: Adata z1 ddr4 16gb 3200
Storage: m.2 wd sn770, and TG data ssd 1tb
PSU: Aresgame agv650 650watt 80 plus bronze
So I booted my pc up and walked away for a little while. When I came back I noticed the red post status checker light was on and that my display wasn't connected either. I tried to wake up the pc then noticed my keyboard and mouse was also not connecting properly. I have tried swapping parts that I have on hand such as a different ram kit and gpu but this didn't help plus as I have said this system has been running fine for nearly 3 years! All parts are the same age other than liquid cooler it's a year newer than rest. P.S YES I have tried many times rebooting and hard restarting! I have also been doing research on other threads.

And when exactly did you "say this"? Because this is an initial post from you and there is nothing else in your post that indicates you "said this". Nitpicky, yes, kind of, but we deal in specifics here so if you've said this somewhere else, you've done it with another account, not this one.

As to your issue, have you at least TRIED to do a hard reset of the BIOS to see if that resolves the issue?

Also, what is your exact PSU model and how long has it been in service?



BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for about three to five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes while the CMOS battery is out of the motherboard, press the power button on the case, continuously, for 15-30 seconds, in order to deplete any residual charge that might be present in the CMOS circuit. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP, A-XMP or D.O.C.P profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.

It is probably also worth mentioning that for anything that might require an attempt to DO a hard reset in the first place, IF the problem is related to a lack of video signal, it is a GOOD IDEA to try a different type of display as many systems will not work properly for some reason with displayport configurations. It is worth trying HDMI if you are having no display or lack of visual ability to enter the BIOS, or no signal messages.

Trying a different monitor as well, if possible, is also a good idea if there is a lack of display. It happens.

I meant to have typed it also in the title. When referening to the 3 years thing. And yes I have tried hard reseting the pc many times. The psu has been in service for nearly 3 years.

At the next sucessful boot look in Reliability History/Monitor for any captured error codes, warnings, and even informational events that may have occurred just before or at the time of any observed problems.

If not sure about what you are seeing then expand the window so all can be seen and take a couple of screenshots of Reliability History/Monitor. First View = Days, and then Weeks.

Post the screenshots here via imgur (www.imgur.com).

Double check the motherboard's User Guide/Manual especially if you changed RAM.

Some motherboards require that the first physically installed RAM be placed in a specific RAM slot - likely DIMMA2.

Lastly: do you have access to another known working PSU that can be swapped in for troubleshooting purposes? If so, try that and remember to use only the cables that come with that test PSU.
