Problem booting a PC

[PurpleGaga27 40]

Recently, the days in CA have been warmer and hotter recently. I have a problem booting a Lenovo 3000 H210 PC (with Intel Pentium Dual Core 2.4 ghz). Regularly when I turned on the surge suppressor, the PC automatically turns on with the fans running and then turns it off again, and then turns on again and the bootup starts correctly. But this time, when I turned on the surge suppressor, the PC doesn't automatically turns on itself. When I turned on the PC, the fans are running continuously (but with a loud noise and faster speed) without stopping and it won't boot, like it's malfunctioning. Then I had no choice but to turn off the PC switch for 5 seconds. I did this several times already.

 

That PC was supposed to be a quiet PC with its fans silently running. The good news is that Lenovo has already stored an anti-virus program designed to protect the BIOS from threats. The bad news is that there's no restart button for that PC.

 

Several things:

1) I recently did not install a program that caused a virus or spyware that affected the BIOS.

2) My room was unusually warm these days, but I would have turned on a bigger compact fan facing the motherboard and the system.

3) The last time I turned on that PC was to eject the disc in the drive and then shut down during the OS choosing menu.

4) I smelled nothing of a CPU burned up after I shut down the PC.

5) After I found tI somehow found out that my video card was very dusty as well as the system motherboard so I dusted them off and there's still no effect on the PC boot.

6) I cleared the CMOS by moving the jumper and putting it back into the original slot and still no effect on the PC boot.

 

Does anybody know a good solution to this?

How long have you had it?

Clearing the CMOS won't help you and that's not entirely how you clear the CMOS anyhow. You have to remove the jumper and the battery to correctly dump the settings. However, based on what I'm seeing here, that's not your issue. If you hear the fans spin up, but nothing else happens, you're looking solely at hardware. There's a high probability your motherboard has a blown capacitor that allows it to receive power, but nothing will function. If your CPU or RAM were bad, you would hear beeps. Since there's no beeps, I can only surmise that the motherboard popped a capacitor, maybe multiple capacitors.

 

The only thing left to attempt would be power off, remove the power cord and hold down the power button for thirty to forty seconds. This will discharge the capacitors and alleviate ESD.

 

In any case, you need to pop the case open and inspect the motherboard. There's a sure bet that a capacitor or two is popped or bulging. If not, unplug everything from the motherboard and reseat the connections. This can help with ESD, but make sure you ground yourself and use anti-static band if you have one.

Anti-static band? Pfft. Real men wrap their arms in copper wire.

I just had this problem last night.

 

@Dr. Destiny, I'll try that if I can.

I had a semelhant problem, but after maybe a week with that problem my font just died... I solved it just changing that

 

btw, a Virus in the BIOS could do this, but it is pretty unprobable you got that kind of virus... i never got a Infected BIOS by myself

I had a semelhant problem

Little Portuguese slip there.

Actually the last part you said works out for me. Now I have fixed the problem and my PC works again. Thanks a lot, Dr. Destiny.

 

The only leftover is to use an anti-virus software to scan for threats and since it's been hot lately I have to use a bigger compact fan to face the motherboard and PC system.

So it was ESD, cool. At least you don't need to replace the motherboard. At least, not yet. I would keep an eye on things and if the problems persists, you'll need to replace the mobo.
