PC suddenly very loud

[Arvis]

So this morning my brother was using PC and suddenly it restarted itself, then when it turned back on while booting there was some message "press F2 to set settings to defaults and continue" or something like that, so he pressed F2. Then computer became very noisy (I believe it's fan working fullspeed all the time?) and also my little overclock seems to be gone (I clocked from 2.6 to 2.9 so no harm) and when turning it on it shows my motherboard logo, it didn't before. So how to set this all back to normal?

The settings have reverted back to default settings. You will need to go into the bios and change the settings again. The boot logo is also a standard option. Your overclock and settings are gone. What you should do is save your settings into a profile (if your motherboard allows it) 1 with default settings and 1 with your overclocked and tweaked settings. Then when this happens you can just load the profile and reboot.

 

Happened to me plenty of times!

Infact I didn't have tweaked in bios anything except clock speed and speedstep. Fan never was this loud and I had never seen this mobo screen from the beginning when I installed this pc, so now I gotta try random settings in bios to get what I had (that is lower fan speed so it doesn't makes huge noise) or what?

The fan speed could be set on a set RPM instead of auto. The settings must of been changed by someone, most motherboards come default with the logo to be shown. In the BIOS the settings are pretty well described, you shouldn't have a problem.

Alright, I'll check it out. By the way any idea why it restarts? I haven't got trojans or viruses or stuff like that, or maybe it could be the tiny overclock I did which makes it restart sometimes?

edit: and thank you, found the right settings in bios, it's silent again

Could be many reasons. You could always check your error log. You could also disable restart on error, which will most likely then show you a BSOD (Blue Screen Of Death), which will list details why it crashed/restarted.

 

To disable, http://pcsupport.about.com/od/tipstricks/h...autorestart.htm

 

Reasons that I can think of are

 

Unstable overclock

Memory problems (reseat the RAM or memory check with MEMTEST (free application, downloadable from the internet) you will have to do 1 stick of RAM at a time)

Overheating problems

Driver problems (restart in Safe Mode (using F8)
