My PC is stuck at BIOS

by Nickra1 / July 16, 2017 8:02 AM PDT

Hello, so I have been playing games today like every other day when I accidentely turned off one of the fans off. When I say ‘turned off one of them’, I mean this: I have 2 little switches on the top of my pc case which are used for switching fan 1 or 2 off/on. So, in the second that happened my PC restarted and when I tried to turn it back on, it just got stuck on Bios and wont exit it. Anyone have any idea?
PS, I tried plugging all the devices like mouse, etc.. off but it still wont let me get out of it. PC is i7, I’ll give other info if needed.

Tell more. How does one turn off fans?

I can't guess how one does that as all the good PCs we own do not allow the user to control the fans.

Why? Because that's a great way to burn out parts. The fans are temp controlled so they slow or speed up as needed. Your story and misspellings have me worried that you are not sharing the full story.

About correcting what looks to be a fatal design error.

Sorry for bad spelling, I am writing over the phone. I’d like to share the photos of the PC case with you so you could actually see how it looks like. Basically, there are two fans and so two switches, under each of them, there is HIGH-LOW-OFF written and FAN1/FAN2. When I turn them both of PC wont boot up at all.. So I guess there might be some config that was set to request them both on HIGH in order to start up PC..

Turning off a PC can corrupt the BIOS settings or even the HDD. You are now into the old PC repair cycle.

Try EASY FIRST. Unplug all USB devices, be sure there is no card in the SD Card or other slots and see if you can get to the BIOS SETUP SCREEN to see what it says for date/time, settings and if it sees the HDD.

As a PC repair tech (you are one now) you work that and if no boot look to trying other boot CD/DVD/USB boot sticks and discs.

I tried unplugging everything and the problem stays the same. For date and time, it shows the current time and a date so I guess that’s okay. HDD is supposed to be seen in boot if I am not wrong and I don’t see it actually. Have you got any other idea..?

Since the BIOS screen does not show a HDD
by R. Proffitt Forum moderator / July 16, 2017 10:53 AM PDT

You (as a tech) need to tackle that issue. Check the power and data cables are connected at both ends (be sure power is off to the PC!) and then try the HDD on another PC or another SATA port. A dead HDD is not uncommon in PCs.

I always boot from my collection of CD/DVD/USB sticks and discs to see if the machine is working and what I can see there guides me to what next.

Do you have some sort of fan controller module in this machine?

If so unplug the input power to the module.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
