Grettings.
My pc has a big problem. As you see in the title of this thread, i cant turn it on. The last thing i did when it was working was change some settings in BIOS Setup. I was changing my IGP Shared memory and i found new things in BIOS setup. I dont know if i already saw that options and i dont remember or if the bios auto updated. I started searching more things to configure and i found Something like, Smart Fan Target Temperature. It was in 50 ºC i changed it to 0 (I think thats the problem). Saved the settings and reset the PC. After that the PC didnt boot. I only saw the Green LED (Power) and DVD LED, i noticed that after 10/25 seconds the Smart Fan starts doing a sound. It was supposed to play a small sound after that and show the "Press Delete to enter the bios config" Screen.

Also my Bios system is phoenix award. (dont know version)

Unplug the PC , remove that small battery from the motherboard and insert it again. Bios´ settings should be reseted then. I´m not sure whether this method is 100% safe, do it at your own risk.

It's safe, unplug computer and keep out the battery for few minutes. I did it more than once in my old PC.
And don't touch bios if you don't know a shit about it.

A tip would be to study on the fan settings before attempting to change any of them. The next thing you would want to do is get some software such as SpeedFan which is freeware from there you'll be able to control your fan settings without much worry. Just don't attempt to change the advanced things as the software contains certain really advanced stuff that has to do with motherboards and stuff, so I can recommend you not to be touching that part if you have no clue what they do.

I also like to say that it'd be easier to control the fans on a desktop PC rather than a laptop one. I say this out of experience as my old laptop's fans broke down pretty much completely and for some reason the screws in the PC does not allow me to access the fan parts... yeah. I say this because the screws literally melt when you attempt to unscrew them. Therefor it's impossible to get them out more or less you can try but without much success. I do hope that it won't happen to my new laptop which I'm using now. Either way for gaming I can tell you that desktop PC's will have more control of their fans than on a laptop PC strictly due to these typical events and problems that may occur.

If you have a laptop fan and want to change out the fan, go ahead and buy a new one a replace it follow guides on YouTube or via various websites through Google searches I swear you can find alot of good walkthroughs on that. Just remember to not "screw up" as they say.

Should be easier to replace on desktop PC's not much trouble there however. Just to be sure follow the same model just pick a better fan model which has best cooling and you'll be good.

If you mean operating system, the answer is no. On a desktop PC it is much easier to find the battery, than in a notebook.

The battery of the BIOS is something else. I don't recommend you to meddle with BIOS settings since you don't even know your own PC. I hope things will work out.

I'd agree partially on that. However you still can access the motherboard in a notebook/laptop PC and replace it just as you can in a desktop PC however the methods of doing just that varies with each unique computer model.

It may seem more difficult to change it. That's possibly due to that you're entirely new to changing out parts in a notebook/laptop PC or you aren't sure about it and you think you'll break your PC if you do anything in there that's my simple guess but it may not be true to all but for some it can be true.

Best way to change motherboard would be to leave your PC at a service, so they could take a look at it and decide what suits your needs best. I've done this a few times. Once I did it when my primary hard disk drive got broken. They then had replaced it with a new functional one at a cost of course. I do know the people at service spots can fix your PC in no time I'd pick that just as a alternative if you don't feel like fixing it yourself when you don't know what to do with your motherboard especially. That's my advice there.

For your specific question I'd try to restore your system to a previous state or run the system with default bios settings. There's probably guides on that out there on the internet. Hope this helps you more accurately.

you can altern the CMOS reset jumper (located in the motherboard of course) to reset the CMOS memory (you did not configure it, with the BIOS or UEFI, correctly) instantly and then back the CMOS reset jumper to its default state

i bet that he actually understood that...he didn't even know what is the BIOS battery...

anyway, the simplest solution to SaskSlayer problem is to remove the BIOS battery(with the pc unpowered), then wait some time(on my old pc, i need to wait 2 seconds to reset the bios), then put the battery back inside, and then plug the pc back, then turn it on and it should work.
