I have an Acer Nitro 5 Gaming Laptop. Specifications: 15.6" (Screen Size), Intel® Core™
i5 (CPU), GTX 1650 (GPU), 512 GB SSD (... An SSD) 8G RAM (As again, it is RAM).
Problem in Short: I was looking at a YouTube Video to try and Optimize Gaming for my Acer Nitro 5 (link, Top 5 Ways To Optimize Windows For Gaming On The Acer Nitro 5 - YouTube). After applying these changes I noticed my computer's performance in gaming... Actually gone a lot more terrible (only game I play is Minecraft: Java Edition. I went from 200-220 FPS to 1-5 FPS). Sometimes Videos on YouTube play at something like 1fps or something, sometimes its smooth...ish but stutters/bugs out a LOT. PC Performance, terrible: EXTREMELY Slow and seems to even have trouble functioning compared to when it ran SO FAST and Smoothly! But I had a restore point, used it and nothing seems to have been fixed.
Aftermath
I keep getting a blue screen (quite a few times now) saying that "A problem occurred something" with a ":(" atop of it. As it restarts my PC trying to "retrieve error information". Minecraft: Java Edition, the only game I play seems to go back to 210-220 fps when I'm on menu (on the F3 menu, which shows more of the mechanics and works of the game, seems to show my RAM being more stable as the memory is not resetting as a lot compared in game (not menu).
But in general my PC Performance is terrible. Trying to type this right now is hard. Its almost like my Laptop downgraded to some cheap $50 Laptop. I am thinking about factory resetting. But I should be able to fix it manually, right? Also I should mention after I got this horrible performance, and used my reset point. The windows settings seem to have gone back. Not sure about the Nvidia, because prior to the reset point I clicked the reset option for the Nvidia Control Panel on the "3D Settings". And it is still the same. Before I changed my settings and clicked went to its "default settings". I should mention my considerably original settings before doing any other of these 2 other setting chances, were different from the "default settings" option... I wonder why. Because it was always on auto-select and still is. However I took a screenshot of the top half of my settings and restored half of them back to original. Remember most at the bottom on what they were and might even be the same as my old settings.
So why can I not fix anything? What should I do?
