hi guys, well I had this laptop for 9 months now it worked perfectly until now.
everytime I play games after 20 minutes or so it shuts down in an instant, so I open my computer and keep playing this time it shuts down in 5minutes, then 2minutes
so I shut down my laptop for an hour and I can play 20 minutes without it shutting down again. I tried rebooting my computer but doesnt work.

Oh another problem that started happening when I got my computer is when ever I alt tab from a full screen program it gets this thing I call black screen, I alt tab and it works but
It goes to a blackscreen but everything keeps running I can hear stuff but I cant see or fix it so I have to restart my computer.

Intel Pentium
Windows 7
64 bit.

Sounds like the laptop is making a south direction. I would rush out on the warranty period if its still covered. The thermal events might have cause this current issues you are having.

The shutting down sounds like overheating, Especially when the shut down time is less and less as you restart but goes back to 20 minutes after it has been off for a while.

As for the alt + tab black screen I can't say.

I will say 9 months old, I'd be on the phone looking for warranty for the black screen. I don't know what their policy is for overheating due to a clogged heatsink assembly.

When it shuts down is there any part that gets really hot?
Before it shuts down is the fan racing?

Those would both point to an overheating problem.

I agree with the other guys.. sounds like a heating problem...
While a coolit pad may help disburse the heat and delay the shut downs... Sounds like it time to open the case and give it a good cleaning....

Agreed, A cooling pad is just a small bandage on a serious wound.

2 ways to go. Call Gateway and ask them how to clean. or
using a decent amount of air pressure blow into where the air comes out. Going back and forth between where the air comes out and where the air goes in until dust stops coming out.

Beware that sometimes there is so much dust built up inside that it can jam the cooling fan and then you have to open it for sure.

However running the LT hot is shortening its life. I've seen that where two always running hot laptops killed the motherboard.

Good Luck
Roger
