Computer turns off during burn?

Hey guys.

There seems to be a problem with my computer.

Everytime I burn something my computer goes into standby and will not turn back on. I have to hold the power switch to turn it off and then back on.

Every time it does this I lose around 4GB of space on my HD and it only seems to do this when I burn UFC or Boxing PPVS that are around 1.7 GB in size and around 2 hours 40mins long. Movies that are around 700mb in size burn fine.

What could be the problem?

thanks

 

Couldnt find the edit

It happens like 3 hours into the burn.

I just searched google, which i should of done first. And some people who have this problem, it seems the computer overheats?

 

Burn doesn't take 3 hours. Are you talking about the
encode that Nero may do before the actual burn?
Check the power options in control panel. Is standby selected ?
Make sure the cpu is not overheating.

 

Yes, my bad, the encoding. It happens around 3 hours and 30mins into the encoding.

Here is what there is

Turn Off Monitor: Never
Turn Off Hardwear: Never

System Standy By: 25min
System Hibernation: Never

And then on the next tab it says Hibernation and there is a disc next to this.

 

In the last sentence, its ment to be tick, not disc

 

Turn off standby and see if it resolves the problem.

 

ok, i have done that. i will check it tomorrow as by the time its completed i will be in bed and dont like to leave it on over night. But wud this be the problem, it says standby after 25mins, but turns off 3 hours and 30 mins into the encode

thanks
