If I want to reset pc completely, should I do CMOS clear and then OS reinstall, or OS reinstall and then CMOS clear? Or does OS reinstall automatically clear CMOS?

OS reinstall won't affect CMOS. CMOS reset does nothing if you haven't touched your BIOS settings.

I have not changed the BIOS myself, (apart maybe from some minor tweak like hardware acceleration a long time ago). But, I did read that clearing the CMOS can remove some issues ( I am having the infamous Code 43 error on my gpu). So I want to completely reset my pc, and I want to cover all bases. Thats why I want to "reset BIOS to factory settings" and "factory reset OS".

Order doesn't matter. Just do both and you'll be fine.

Thx hltv chads !

Reinstalling doesn't reset your BIOS or UEFI. Reinstall first, then reset BIOS/UEFI either by removing the CMOS battery for a few seconds or through the BIOS/UEFI itself.

Okay thanks. But does the order matter? Why not reset BIOS (clear cmos) first, and then reinstall windows for example?
2019-10-09 17:15
Because there is a chance that you made a change in your UEFI that affects something on your Windows installation. But there isn't any persistant change you can do on Windows that directly changes UEFI settings. The point of uninstalling Windows first is that you know it's going to work. If you've made changes to your UEFI at some point that you can't remember and revert them without making a backup then you don't know if everything is going to work afterwards.

Throw away HDD and buy new. Then douse PC in water.
2019-10-09 17:16
you mean dowse it in milk and salt? it is a common mistake so i will forgive you.

Little known fact, ketchup is very useful. Also mayo.

i heard if you blend up half cooked eggs you can put them in the cpu fan to get better thermals.
2019-10-09 17:20
I heard that too. I also head it can help ventilation to put oatmeal in the vents
2019-10-09 17:21
YES! I was going to try that one. The other one im going to do is put duct tape on all of the mesh and vents so dust can't get through.

My favorite of all time though has to be the throw test. You know where you throw your PC across the room and it moves so fast it works faster afterwards
2019-10-09 17:25
my friend did that one and it totally worked. Sometimes I do the loop hole where I paint my pc black so it can run faster, but then it usually doesn't work.

You didn't know each RGB component adds 15% fps??!
2019-10-09 17:27
I did not, thank you. Have you heard of the ice cube test? It is where you put an ice cube on the cpu fan while you are playing a game. The time in seconds that it takes for the ice cube to melt is how many theoretical fps your computer could have in that game.
2019-10-09 17:30
Hmmm... I didn't know that! When I get the chance ill test to see how much more RGB I need

Clear CMOS and then format you disk directly after on startup Edit: not that I think it's going to matter in any order you do it really but you know

Okay. But the guy above says to reinstall first and then clear CMOS. Does the order not matter ? Edit: ok, so order doesnt matter basically
2019-10-09 17:17
Clear CMOS is for BIOS reset. I would clear CMOS and then format.
2019-10-09 17:17
OS reinstalation have nothing in common with CMOS

reset bios first (just go in and reset to defaults) really no need to do this though unless you have been messing with settings in there? once done you can format/reinstall os
2019-10-09 17:21
If you feel like cmos-resetting, you should do that before installing your OS. Before resetting cmos, make sure to cut the power to your mainboard by switching of your PSU and waiting 30 seconds. As #15 - but general rules of thumb say that resetting your BIOS settings to default, saving and rebooting - before updating your BIOS - is the proper way of doing it. Why reinstall OS in the first place? Hardware changes? Too many mice or rats crawling around?

Error code 43 for my GPU after system restore (had gray screen crash issues ONLY WHEN GAMING). However, checked temps, and it was always between 30-55, which is acceptable. Now pc doesnt want to use the GPU, even though ive dabbled with the gpu drivers to no avail. So im currently using the pc with the built in graphics, 1 HZ display. Might be a hardware error, but I did read that resetting/updating the BIOS might resolve the issue. Im basically trying to eliminate options of what the issue may be. If software 'cleansing' doesnt work, I will send my pc in to a computer work shop and have an expert confirm damaged GPU before I give up on my pc.

Also idk man, you and many others say I should clear the CMOS before reinstalling OS, however #25 makes a seemingly valid case for doing it the other way around. So im torn rn. And you say I should cut the power, but I read that you can clear the cmos by software "The easiest way to clear the CMOS is to enter the BIOS setup utility and choose to Reset BIOS Settings to their factory default levels." lifewire.com/how-to-clear-cmos-2624545 Maybe the author is wrong, maybe clearing CMOS (by actually resetting the battery physically) != resetting BIOS in settings? Either way, obviously I would disconnect all cables before opening up my PC, but maybe u mean something different?
2019-10-09 20:19
CMOS holds BIOS settings, clearing it just resets everything in BIOS settings to default. If you haven't changed anything then the only effect it'll have is possible hiccups due to memory training for BIOS to adjust RAM settings.
