Bug: PC beeps 3 times and off violently. Virus?

[Kirt]

Everything started when I was trying to watch a streaming that resulted the pc beeps and then died. The PC running normally. I wanted to do a scan Adware. And then of a sudden 3 beeps (small, more serious and small as when antivir detects a virus) and the pc shuts violated. I try not to fail. Unable to open adware. I run a scan antivir and towards the end of the scan, the same 3 beeps and pc off. My pc is a Dell Inspiron 9300. What to do?

It is connected to AC when the problem appears? If it is connected to AC power, is the sector indicator lights up on the laptop? Perhaps the battery becomes weak and does not want more charge or is recharged.

The pc is on the sector. The LED is ON. Everything works on this side.

Ok, in this case, indeed, perhaps a virus, but I think so too (ever seen virus that caused this kind of thing, but it is possible). The best would be to reinstall windows, at least you would fix, but it will start in Safe Mode to save your data before.

What I think is that the PC works fine. This bug if I run a scan it is (and apart from streaming). The scan antivir detects an infection, but the pc beeps and plant before the end of the scan ...

It may be too hot, and warns you before shutting down (3 beeps). Dismantle it and pass some vacuum (if it is not under warranty)
