    I have an Acer Apsire 7741z and it starts up without an issue, the screen appears without any problems but after about 10 to 15 minutes the screen begins to flicker and then goes blank but the laptop is still running. I then let it cool down for about 5 minutes and turn it back on and it starts up and the screen again flickers and goes blank. I tried hooking it up to an external monitor but it's doing the same thing with the monitor (it goes blank and I get the No Signal message) What can it be? Thank you in advance for any help you can provide me with.

    Sounds like it could be heating up. Check your vents and make sure they are clear. Also, try this little program to check out your temps. The 1.21 English is the Free one that you want to download. Post your temps here when you get them.

    the video chip may be overheating

    are you using it on a hard flat surface

    I also hooked it up to an external monitor and noticed it flickers externally so I'm ruling out the screen itself being damaged. I noticed it was warm by the monitor port. Is there a way to set the fan to kick on sooner? Could it be a bad fan?

    Is it replaceable or do I now have a paperweight?

    I let the laptop sit and am literally not doing anything on it.

    it will be on the sensors tab if it reads it

    cpu temp is normal would not think it caused the blackout

    i just found this on a review of the laptop which would throw a different light on it

    Intel Graphics Media Accelerator (GMA) HD Graphics: Onboard graphics card that is built in the new Arrandale CPUs (Core i3 / i5 / i7 Dual Cores). Depending on the model and Turbo Boost, the GMA HD is clocked between 166 and 766 MHz.

    it is part of the review here

    http://www.notebookcheck.net/Acer-Aspire-7741Z-4643.44581.0.html

    how old is laptop the laptop may be out of warranty,but i would check if the cpu is in warranty

    So with all that said it's pretty much dead and I have to return it to the manufacturer in the hopes it's under warranty still. Correct?

    Thank you for all your help people
