PC became broken yesterday. Symptoms started appearing few days ago when PC started to freeze while I was watching videos full screen. Complete freeze and unresponsive, cursor doesn't move, no sound, only solution was to reboot. But that was only a temporary solution. Freezes keep occurring even outside of watching videos, just freezes when I'm AFK. I just kept rebooting and at one point reboots just doesn't restart PC just shuts it off. And power and reboot button doesn't work, so i turned Power Supply switch off and on. Before this happened, out of nowhere, pc shuts off without warning. I wonder if it was the constant reboots due to freezes that might have damaged the PSU.
Now, after the freeze yesterday and I tried to reboot, complete nothing. Only the fans and lights run when i try to turn on the computer. No display on boot on monitor, but I'm pretty sure the monitor works. Might be virus?

And, I recently installed PCI wireless adapter card and 2x4GB ram a month ago, and it showed no problems; not sure if those two might be conflicting with anything

specs:
msi radeon rx 480 8gb
amd eightcore fx8320
m5a97 le r2.0
cx430 psu
kingston 2x4GB g.skills ripjaws 2x4GB RAM

pc fairly old, had it for 5-6 years

also, i did overclocked CPU to 4ghz from 3.5, but after few freezes i was paranoid so i went into BIOS and resetted to defaults. and i think that when pc started to not boot on anymore.

Still not sure if the problem is Motherboard, CPU, PSU, RAM, or virus.

I tried testing if MB works yesterday by removing all ram and video card and tried booting after resetting CMOs and MB did beep; so i assume it still functional.

Please, i require some assistance to determine the causes and if there is a possible fix? maybe mb,cpu, and psu replacements?
thank you

1) When you reset the BIOS setting to default, you should make sure the boot device is in the 1st boot order or not, or check the boot device is coneected to the 1st SATA port, because usually the PC will boot the device that is connected to the 1st SATA port. Also check the storade mode is ahci or IDE, etc.
2) Try use only one RAM to boot the PC, may remove any add-on card too, like the wireless card, you should use the minimum hardware to test, if the PC has problem to boot.
3) Try other GPU, or other PSU, because the rx480 + oc fx8320, you let the PSU works very very hard to power up your PC, even it can't provide enough power, that will cause the pc rebooted or frozen.
4) Maybe the MB VRMs section overheat, that will cause the pc...

4) Maybe the MB VRMs section overheat, that will cause the pc reboots too, because the LE version has lower power phase count, if you don't oc the fx8320, it is fine.

You title sounds funny, like "my car doesn't start but it will get me to work!" it turns out your definition of RUN is turning fan blades and some lights coming on. :)

First I make sure I can boot to BIOS,
Then I run a s.m.a.r.t. util to ascertain the health of my HD.
