Too lazy to type up another report, but here's what I posted on /r/techsupport yesterday. I don't think there's any mega computer geniuses on sim monsters, but eh. Might as well.
This may or may not be a virus, hoping not.
So I turned off my computer to go to sleep and left it to shut down while I did something else, I came back two minutes later, and the power light is flashing, and it's revving at me like it wants to race me. After some hurried sleuthing I figured out it does this whenever connected to power (although I have not yet had a chance to use another outlet, other things work fine in this outlet). The on off cycle can only be stopped by turning off the power supply or unplugging the computer. Here is a video
Things to know: -It's a Lenovo H420 desktop with a GTX 560 that I put in, and a corsair cx500. These are the only modifications other than a replaced disk drive, and all of these were done over a year ago.
-today I used a seemingly faulty dvi input/dvi to VGA adapter/VGA cord to finally buy a new monitor that I have wanted to for a while, probably unrelated, but you never know...
-the computer has never randomly blue screened.
-every now and then, like weeks apart, when it would turn it on I would be met with a screen with the logo of the company that owns Lenovo, I think, and saying some error that I didn't record and didn't understand, it gave me the option to start anyway which I always chose, and it worked seemingly fine.
-I just ran a (granted Norton) virus scan on huge computer Saturday and it found no issues.
-being a teenager with no life, the PC gets a lot of use, but hasn't slowed down or anything, this is the first time I've ever had any real issue.
-the hard drive light is not lighting up meaning that it's not being accessed, unless it is for a small amount of time before the computer turns off again, and before it can even indicate its usage.
Does anyone have any idea if this is something simple? Or should I have saved my money one more day to pay for a large repair or worse, a new pc?
Thanks!
Edit: It runs Windows 7 64 bit OS
Someone suggested to disconnect the powers which if possible (seemed like a bad idea when I went to do it) and reset the bios (this was done by removing the CMOS battery for 30-40 seconds). And nothing changed really.
So if anyone know what might be problematic or knows of any good tech support forums or something to take this to that'd be great. I, not too enthusiastic about taking it to a computer repair place because all I ever hear is that they reset your hard drive and that's the last thing I want to happen.
Thanks I guess.
