Good day people. I've used help here once, some time ago, so I decided that I could make another try.
Good friend of mine is having a PC since 2011. I've chosen all parts for him, put them together and made sure, that everything was working well. Some time later their OS broke down, some "specialist" decided to reinstall it. Without my Agnitum Outpost Firewall (I've gave him the license). It could be important for later story, because when I checked their PC I wasn't being able to enter BIOS.
Quite simple thing turned out to be...quite hard. Either CMOS reset and battery reset gave no results. What's more strange - when I decided NOT TO enter the BIOS...PC worked. If I pressed del on keyboard - magic happened. Either PC stopped on "wait" on main screen (rest of it was black) or on the line "checking NVRAM...nu". None of the options worked, error was repeated several times.
Last weird thing is safe mode - you are supposed to have a chance to update your BIOS, right? Not this time. I've done (at least, that's what I'm thinking) pretty much all of the things in the same pattern. In safe mode, I've run cmd.exe and began to enter localization of file manually. Not sure why, but even in safe mode, You are NOT allowed to update BIOS. Command prompt told me that "XYZ.exe isn't in that dir.". It was there, any other file (two *.txts, one *.0 (?) ) run well. Or at least, command prompt told me "hey, you've got something here!".
Is that some kind of deeply hidden virus? Or just a hardware malfunction? Could it be repaired?
I, myself - don't have any clue, what to do. I doesn't smell any...smell ( :D ), speaker is also telling me, that everything is ok (one, short beep, after bios check. Does not appear, when I try to access the BIOS). Before I've checked PC, it keept doing one long and three short beeps. I've checked it in internet - NVRAM error. After plug-in and plug-out power cable + some magic (yea, included taking off piece of case and doesn't include anything else) it disappeared. Have no clue, at all. Broken parts should remain broken, especially if they are in PC.
Or maybe, I'm the one who is mistaken and some PC can actually repair themselves without replacing broken parts?
