Stops randomly v3 - 771 g Acer Aspire

I bought the Acer Aspire v3 - 771 G. I had no problem with him, but lately it stops at random without any warning, as a power failure. I checked the CPU time and overheating is not the problem. The computer is on a Targus cooling pad and it dosen't get hot around the fans. The problem occurs when the pc is running games or process (analysis of the computer) that require more memory than when I am surfing. The problem happens everything from 15 minutes to 2 hours in a game or two (based on the amount of memory used). I did some research myself, and it seems to be a graphics issue.

The computer is always the minimum requierments for games that I play and I play on the rather small graphics on all games (to delay the judgment).

The second problem is when I'm streaming or see a movie, the screen turns randomly into a "snowstorm". Tried to move the screen up and down thinking, it was something wrong with the cable between the hardware and the screen but he has not responded to this. I don't know what made this happen because of the careful manipulation of the computer. But the only thing that comes to mind is something wrong with this cable... This problem occurs randomly and started last week.

I did some basic problem solving, with no success. I tried to restore the computer to facotry setting, updated the bios and all the pilots involved.

I looked for a program of diagnosis of hardware on the computer itself (as many other brands have) with no luck, even looked on the web. But nothing I've tried seem to find the problem.

The specifications of the computer:

Acer Aspire v3 - 771 G

Windows 8.1 (supplied with Windows 8.0)

Intel Core i3 - 3110 M CPU @ 2.40 GHz 2.40

8.00 GB (RAM)

64-bit operating system

NVIDIA GeForce GT 630M

It of a clean computer handled with care and is located in enviorments little dust (not in bed without scratches) or bumps.

Boards, or what is happily taken.

Any ideas before I have to send it to the service?

He sent just this ad serving, if some happens to have same problem. Seemed to be a problem with the motherboard. They said it was running unstable. They replaced and it works fine now.

  • Acer Aspire D255E turns on, displays on screen, then stops in a few seconds

    I just bought an Acer Aspire D255E with a cracked screen.  I tested it and it worked fine.  Replaced the screen with a new brand, and the result is that it turns on, shows the opening screen, flashes what looks like the screen you get when you stop abnormally, then powers down.  It if also out tension in all the time even though I have F2 in the BIOS.  Anyone know what is happening here?

    Hello

    One of the panels for the Aspire One D255 2677 LCD part numbers is:

    LK.10105.002 - AUO B101AW06 V1 LF 200NIT 8MS 500: 1---> you have the right part.

    You wrote:

    "I forgot to take the battery when I first changed the screens, but it does not appear that should hurt anything."

    Unfortunately, Yes. If you have a small power surge when you plug in the Panel, you have damaged it.

    You can connect an external monitor or an LCD TV using the VGA port. I hope that you have not damaged the neat chipset.

  • My Acer Aspire 4736ZG stop each time I start and will work in safe mode

    This problem has been some time now. Whenever I turn on my computer notebook (Acer Aspire 4736zg) close at boot (windows loading screen) and it really means not freeze SHUT DOWN or restarts... He likes to lose power. It only works in safe mode. Installation of Windows 7, 8 CD cannot start (stop as above).
    I did everything: fixing driver, scan virus, chkdsk, update BIOS even install new windows... The problem still there. I tried install Joli OS (Linux) to have a chance but does not work (always closed).

    All ideal for my problem?

    P/S: sorry for my English

    At this point no matter what the problem he is going to need repair. If it happens with more of an OS which pretty much eliminates the possibility of a software problem. I would still say that it is probably overheating, or there is a problem with your graphics card. However, you will need to speak with Acer on this one.
