FAQs - BIOS
Here you will find questions and answers to common troubleshooting topics.
Why does my computer reboot itself randomly?

A computer shutting down or rebooting can be caused by a few different things. The 3 most common are a power supply going bad, motherboard going bad or the computer overheating. If it’s just shutting down then it may be a case of it over heating. You can go into the BIOS and see if you have anything set to shut off the computer at a certain temperature. This setting is to prevent the computer from being damaged from overheating. You can also let it run in the BIOS and watch the displayed temperature and see if it keeps rising.

The second is when your power supply is going bad. The power supply provides power to all of your hardware components. If it is going bad then it can just shut off as if you unplugged the computer. They are fairly easy and cheap to replace. If you have a name brand computer like a Dell it may have a special non standard power supply. Otherwise they are about $60 and will take about 20 minutes to replace if you are used to replacing components inside the computer.

The worst case scenario and unfortunately the most common is a failing motherboard. This will cause random shutdowns, reboots and Windows errors. There is no real method to check the motherboard at home and if it’s bad then it’s the hardest part to replace since everything else is connected to it. If you don't get the same type then you will have to reinstall all the motherboard drivers to get Windows to recognize the new hardware. Or if you don't need to save anything you can do a clean installation of Windows or a restore from your recovery CD. Getting a new motherboard may also require you to get a new processor and RAM to match the type of motherboard if your original motherboard was an outdated model.

You can also look at your Windows Event Viewer to see if it tells you any issues that were happening around the time of the shutdown.

When I first start my computer it will go so far on start up then it says to press F1 or delete and it won’t go to windows until I press F1 then its fine. What do I do?
That usually means that there is a conflict in the configuration with the computer. Many times just going into the BIOS/Setup by pressing delete and then saving the configuration (usually by pressing F10) and exiting will do the trick. If its a consistent problem that comes up again you may have to go through your BIOS settings and double check everything or even try setting all the settings to default. If you have made changes you may want to write them down but most likely you haven't. If you installed any new hardware that may cause this message as well. It can also mean your CMOS battery is going bad or you may even need a BIOS upgrade/flash.

How do you fix a problem on a computer when it beeps five times?
When your computer beeps like that it's usually a code telling you what the problem is. Then you can look up the beep code and try and diagnose the problem that way. The problem is that if you don't know who makes the BIOS of your computer then it may be hard to find the right cause of the beep code. You can look at various codes from different BIOS manufactures to try and narrow it down. Or if your computer starts enough to show you the POST screen where you can press the certain key needed to get into the BIOS then you should be able to find out who makes it. Many times it will show on the screen as one of the first items during startup.
