Something I would mention in regard to this is, how are you sure that the motherboard is the only thing wrong? What symptoms and troubleshooting occurred to lead you to this conclusion?
Honestly that is the main problem... Since you've asked, let me explain to you what happened:
I usually service my pc once a year or two when I notice a decent loss in performance or certain issues, though quite frankly there's little to no good performance to begin with since the parts are old. I've had lots of issues with this pc but nothing I couldn't fix or possibly take to a technician to get fixed. One huge issue I've recently found out, by browsing this same forum, is that my PSU apparently is not enough to give enough power to my components all this time. Which makes sense since the majority of my ports in my PC don't function for no reason, even if the driver's were up to date, resulting in me buying a usb hub. But the point is, this pc has had hiccups and issues for a while.
So on March 17th, I was using my pc, talking to my girlfriend on discord and watching a stream of her playing some game for me. Whilst I was doing this, I was organizing my uni files and I've had this application called teracopy, which was on my pc for around two years now, giving me issues whenever I tried to copy a file to any location. It said some sort of access violation or something of the sort though honestly I can't remember properly anymore, I apologize!! But the thing is it never gave me any issues but these popups start coming up for the past two days every time I copied a file. I was quite irked with it so I thought the best course of action would be to reinstall the application to fix it, and that's what I did. I went to uninstall it and while it was uninstalling in the little uninstalling box, it said "gathering require information" and afterwards the uninstallation crashed? It gave me an option to cancel, which I clicked. But when I did that, my whole windows went to a black screen, I couldn't press anything, my windows button didn't work, nothing worked except my current open applications.
Here's a screenshot of it. You can see my sticky notes and discord app opened but my wallpaper, my task bar is all gone.
Afterwards I panicked and I tried to restart my pc, but when I start the pc, there would be no signal coming from my gpu for some reason. It wouldn't even show the bios screen because it didn't give any video signal. So I tried the following things:
- Reseating the GPU
- Reseating the RAM after blowing on it for a bit in case there were dust
- Reseating the cmos battery
- Removing the sata cable for my secondary drive
None of these worked. So I called in a technician. he was confused as well as I was, but what he did was he removed the GPU, plugged the hdmi into the the motherboards hdmi socket, and it gave us a display for once!! We could go into the bios, but when it tries to load into windows, there's a circle that keeps spinning indefinitely and stops. He and I both thought that my boot drive (SSD) was being faulty so he formatted it and plugged in a usb with the windows OS installation and reinstalled a brand new windows OS into my boot drive to see if it'll fix anything, but it didn't, it gave the same issue, and my secondary drive wasnt plugged in at all at this stage btw!! So because of that we were stumped. He tried installing a brand new version or Windows into one of his new hard drives and tried to boot into it by changing the boot order in the bios and it's still spinning indefinitely and gets stuck. Which is why he concluded it's a motherboard issue! It really really doesn't make sense to me tho... But I figure these parts are old so maybe that's why?
I apologize if this is all a jumble and doesn't make sense but I tried my best to give a good reaccounting so you could understand what happened!! If theres any clarification please do let me know because more than buying a new part I'd rather fix this bc my family is not doing good financially unfortunately!!!
Thank you for reading it all if you did!
