I recently built a new PC buying new components thatt include a Corsair V2 CX650, Ryzen 5 5600, B550M DS3H and using a 1660 ti from my old PC. After two weeks of the PC running just fine, my room suddenly got filled with the most vile stench like a rotten egg or something, while I was playing. I didn't think much of it and discarded it, but next day while playing the same game it happened again. I couldn't really identify the source of the smell, but it was more powerful in the area of my pc. Upon closer inspection, I realized that

1. No insects have been trapped inside the case

2. The motherboard circuits don't appear to have melted or something.

3. I noticed a highly pitched sound coming from the monitors power supply, even after the PC being shut for more than 10 minutes.I suspect the circuits inside that thing might have melted or something, I've had this monitor for like 6 years now, but I want to hear the experts' opinion as well.

If anyone can pinpoint potential causes it would be greatly appreciated

I recently received the parts to build a new PC, so in order to get everything ready before welcoming the new PC and selling the old one, i needed to install Windows.

So i commited the major mistake of installing the windows installation media into a Sandisk Sport Clip MP3 player 32gb instead of a regular USB. The MP3 player's software has been destroyed for days now, cant get it to function at all, shows a grey screen when i turn it on and when i plug it into my pc, it says something about a malfunction device that obviously doesnt work as intended

I tried multiple fixes which none of them worked, so Im open for any ideas that might bring it back to its normal state. Is it beyond saving?

It's my first time building a PC by my own so I'm struggling ,but with the help of a bunch of tutorials I think I've done a decent job so far. I ve done all the preparations so far but the only thing left to do is to... unplug my HDD from my old PC. The old PC was prebuilt and it came with a WD blue Hdd with 1TB of storage. I wouldn't mind throwing it away and buying a new one but I kept it purposefully since I have a lot of important files in there. I've unplugged the connections it has with the power supply so the only bond it has left is the screws. I've been using PH 2 screwdriver the entire time for the whole building process which didn't work though. I tried using PH 1 ( or 0, I don't know it's the smaller one), flathead and even pliers with none of them being successful I genuinely don't know how to remove the screws
