Laptop rebooting itself during burning

[rock_king_my]

Hi all,

I got an ACER Aspire 4920 built in with Pioneer DVD-RW DVRKD08RS rewriter.

Bought it back in Dec 2008 the writer works ok until recently.

Now my lappy keeps rebooting itself halfway during burning when using NERO 9.4.13.2. Thus tons of wasted DVDR discs (I don't use CDRs anymore). Same thing if I do "Simulation" only.

I also noticed that when playing movie files or DVD movies from DVDR disks, [burned previously prior to this "writer rebooting" came about], the audio seems to "stutter" a little bit thou the videos looks like running smoothly. Audio is OK when playing movie files or DVD movies from my hard disk.

Are there any software / checking I can do to see where there problem is coming from/to fix the problem?

I tried using an "external" writer with the laptop & all is ok this way.

Thanks.

When is the last time you have had the dust blown out of the computer. Sounds like it is over heating and shutting down.

Dust blowing?

Err never I think.

How do I get the "dust" out of my laptop?

So are there any software / checking I can do to see where there problem is coming from/to fix the problem?

Get a can of compressed air like from Walmart. Then from the bottom of the laptop remove the access panels that have screws. Then use the compressed air and blow out the dust. Especially the fan and the fins on the radiator type heat sink, which is the one that has the heat pipes from the CPU to the radiator. If you do need pictures I can take some as I do have an Acer laptop, but it is only an ASPIRE.

Hi.

Yes some photos would be great. I myself use a USB 3-fan laptop cooler under my lappy all the time.

Do I have to unscrew my lappy?

As soon as I find my camera I will post pictures.
