[SOLVED] PC - CPU or Mobo ??? Any Suggestions

So I'm trying to figure out what happened to my pc here. This was my first build, and it's been about 2+ months and it was running perfectly. The other day I was running a program and watching youtube while the program did its thing. I noticed a few drags that day. Videos wouldn't play all the way through etc etc I kind of just wrote it off as the program I was running was bogging down the pc. Eventually everything froze, and I had to hold power button in to turn it off. At some point before or after I turned the pc on the screen was nothing but static. I can't remember if it was before or after. Since then nothing shows. The monitor says received signal, but nothing ever shows up. The monitor and hdmi cords etc are fine I'm using them now.
I've re-seated and tried both the GPU I purchased, and the onboard/integrated gpu and both give the same result. After turning the pc off maybe 2 or 3 times I couldn't turn it off by using the power button anymore. When I hold it in the light just blinks until I let it go. I didn't realize this until today that I haven't been hearing any beeps, and can't really remember if it ever did or not lol but I haven't heard any beeps. I've removed everything and re-seated. Started the pc without the 1050 Ti gpu and no RAM (also swapped them in and out). I've tested the 24 and 6 pin connector from the PSU and all the voltages are fine. All of my google searching and stuff I have read on these forums seems to teeter between CPU and motherboard but mostly towards the CPU. Oh when I turn it on the fans and everything turn on also.

Yes. Those voltages are read under 0 load. Once a sufficient load is applied or demanded, it's possible the psu cannot supply it and voltages will plummet out of acceptable running range.

Check every wire, not just the connection. It's possible for pins to get pushed out of the socket, so you'll read voltage, but the component demanding the voltage doesn't get it.

It's also possibly a corrupted bios. If that hangs up at/before post, you'll not get the post onscreen, it'll be blank. No beeps either, as post doesn't even really start. Pull the plug, pull the battery, hold power button for 30 seconds. Remount. That'll clear the cmos, forcing bios to start from scratch. If your board has a dual bios, flip the switch to the other.

Cpus...
Maybe board, but sounds more like a psu prob. Maybe the os.
But with cables i would be careful, had a dp that was working fine, but once in a while i would get out of range on the moni, even that nothing was changed, didnt even "move" my stuff, and a different cable fixed it.
I would try run memtest 86+ for at least 3 better 5 runs (stock settings),
If it doesn't stop/shows errors, run prime95 (nothing else, and try disabling as much software as you can, like av etc, and see if it runs for a couple hours, better 24h.

It turns on and the fans spin and tv doesn't receive any signal message on tv. That's about as far as it gets. Its not the HDMI cord or the monitor. I only know a little about a little, but if all the voltages from the connectors are fine could the psu still be messed up?

Cpus are notoriously hard to kill if left alone, only user abuse from OC or installation destruction by bent pins etc can damage them. Life expectancy is 20years plus. Mobo's and psus aren't that hard to kill at all. Bad voltage outputs, spikes, aggressive OC, even simple things like plugging in a gpu or ram wrongly can destroy a mobo. And the ball-solder technique is nowhere near as reliable as hard point solder. So yes, it could be a mobo power delivery issue if the VRM's are shot.

Since the psu actively powers the fans, which are related to bios not cpu, I'm inclined to believe it's not a psu issue, but probably a motherboard issue. That TXM has OVP, OCP, OTP, SC protections, but not UVP, so can't tell if it's suffering from under-voltages

Only way to tell is get a friend who'll let you put gpu, psu onto his system temporarily or if you have alternates you can swap in.

If you're resetting bios, make sure to load defaults, reboot and load optimized (defaults) if you have that.

Ive seen more broken psus causing problems, than broken (for no obvious reasons) boards.

because the fans are spinning, unfortunately doesnt mean anything.
And corsair doesn't make them,
so they have big differences in quality,
and iirc, the tx wasnt as good as the brand would make you believe.
