My PC used to be LIGHTNING Fast Now its slow

[KadeyGlticher]

Hello, So i have my PC, Optiplex 9020 with i7 4790K with 4gb ram, My pc used to be factory windows 7, So i had to update my windows as i was recommended to do so if i want to game, so i had to buy a new GPU, GTX 750TI 2gb and i also upgraded to 8gb ram. Anyhow. before applying the graphics card, i installed windows 10, then back to 7, then back to 10, and now im on 8.1, I noticed my pc is stuttering, taking long time to do stuff and im really worried about this. is there anything that could have gone wrong doing this? Thanks

Dose it take long for you PC to boot?

If I were you, I would re-install your factory Windows 7 from scratch.
If I had £60 spare, and didn't want to risk losing all the stuff on my hard disk I would get a Samsung Evo SSD, then install factory Windows 7 on that instead.
Once I got the computer working properly with Windows 7, I might then upgrade to Windows 10 or 8.1, but I wouldn't do it more than once.
If i had a bit more money and I was running 64 Bit Windows, I would increase the memory to 8Gb
Good luck

I think your hdd is too defragmented. Benchmark your read/write speeds using a software (e.g. CrystalMark) while also monitoring cpu and ram usage. What is your ram configuration? They are the same model? Have you bough a 2x4gb kit or just added a 4gb stick. Test the pc with only one stick of ram (test each to see if that solves the issue). You could also have a bad ram module. Also, you can try reverting to factory settings or doing a clean install. P.S. I also highly recommend you to get a ssd (e.g Samsung 850 Evo).

did you just downgrade back to windows 7 or did you just do a clean install when going back? all the upgrading and downgrading may have bogged down your system. so i too would suggest just going back to factory settings. also if you don't want to worry about slowdowns in the future i highly recommend getting an SSD if/when you can

a good minute some times 20 seconds

yeah i think all the downgrading have caused my pc to slow down. i really want it the old way it was. im trying all of the suggestions atm hopefully i figure out a solution

Just do a fresh install of windows, and see if that sorts the problem if not maybe get a SSD put an OS on it and see if that works good luck.
