My PC is having major problems.

Hi There,

Firstly, I want to thank you for taking your time out to read this, this is a very interesting but scary problem I have going on and I have no clue on how to fix this issue.

I was playing some games 3 days ago until my PC black screened and completely turned off, I tried starting up the PC and it didn't turn on. I diagnosed this issue and I found out it was my old power supply that went and my motherboard had completely shorted out. So I replaced the two...
I then put the new parts in and then noticed none of my windows icons were showing. It was showing the "White Page" Placeholder icon on all of my icons. I thought that maybe the current windows version was messing with my parts since I changed to another Motherboard. I then fully reset my PC, once I had done that; My PC was missing Microsoft Store and I couldn't install NVIDIA Control Panel, I thought maybe there was an issue with my Windows Version, so I looked online and found out I had to run "wsreset.exe" and other stuff, but I had no luck trying to get it, but when I clicked on NVIDIA Control panel in the windows search, It let me download it which was strange... but I moved on.

Then today, I was playing some games like usual, then I went toilet, when I came back my PC had black screened and was BURNING hot, I could smell something was burning.I disconnected my PC to the mains, and turned off my power supply using the button on the back, I then opened my case, waited like 30 mins for everything to cooldown, and then started it back up, It turned on but went off in a flash, I then turned off and looked online, I tried taking out the CMOS battery, waiting 30 seconds -2 mins and then starting back up, then I tried taking out the RAM, moving them around, Trying them with and without, still no luck, and now I am left without options...

What do I do...

Just to clarify, the Motherboard was working Prior to this "Burning" event...

Usually, "burning hot" doesn't mean much because human skin is a bad measure for PC components. But, the smell of smoke or burned plastic is a concern. You will want to inspect the PC for damage physically, stripping out down will be a pain but necessary. 

 

Start with the power supply, this happened to my living room PC very recently. PSU puffed the magic smoke.

So, to recap, PSU failure smoked the mobo, and after replacing both, system is now dead again after showing obvious signs of overheating. My first two thoughts are the processor and / or other components were compromised and caused the new board / PSU to fail, or you just somehow managed to get two bad PSUs in a row.

 

Word to the wise -- PSU failures are known to nuke entire systems. I've had one do it so bad my backup hard drive was knocking its heads against its casing. I'm not sure I'd want to trust anything from the original system at this point -- just my $0.02. Salvage what data you can from the drives and start fresh. Side note here, you may want to have the building checked for electrical problems, such as line noise, voltage sags / surges, etc. You'd be surprised. My UPS catches about 8-10 occurrences of electrical noise per day, with 1-2 sags on average per week. And I would say a ground loop / fault could have caused all of this, and yes, out of nowhere.
