Acer aspire one 722 has a fuzzy screen.

Specs: Windows 7, 2gb/amd c60
This Acer netbook seems to work normally. But if you run processor intensive applications such as youtube videos, the screen goes blurred ,, fuzzy and the graphics are unreadable. There is no answer to this other than powering off the laptop. However, if you start the laptop again it works normally.
It can run ok for an hour or more especially if running less processor intensive applications. However sometimes if goes fuzzy after only several minutes of use.
I tried starting in safe mode. It doesnt get the fuzzy screen, but simply freezes instead.
I suspect the graphics chip. Any ideas? Would a blast on the graphics chip with a hot air gun solve this?
Also, anyone know how to change your username on here?

Hot air gun probably wouldn't have enough air flow and may melt plastic. I wouldn't recommend that.

Sounds like your laptop is overheating. Are you using it on a hard flat surface? You may need to use a blast of canned or compressed air to clear out the vents on the bottom of the laptop. That is a common issue with laptops.

I thought it was a heat issue. I have explored that possibility. i tried replacing the thermal compound. have tried both arctic silver and a cheaper one. Both have made no difference. I have also tried using a different fan/heatsink. I don,t think heat is the issue. It puzzles me as it is showing symptoms of excessive heat. Having tried the usual solutions, I am not sure that heat is the issue.
I also have cpuid instaled and the laptop cpu temperatures seem normal foa an AMD cpu. they do run hotter tan Intel.
I suspect the gpu.
Thanks for contribution and the tip about username.

The vents on portable computers are prone to picking up dust and dirt. You need to blow them out. Netbooks are potentially even worse due to the small size.

You probably should use the heat sink that came on the processor.

Just install a monitoring program to determine if it is heat. Download and run HWMonitor. It can run in the tray so you can see in real time what the temperatures and voltages are. Get it from the link below.

I have completely dismantled it. So, the dust thing isn't an issue. I have cleaned and removed the heatsink/fan etc. All dust was removed when I dismantled it.

I have already installed cpuid and the netbook runs at 58c when idle and about 78c with you tube videos. its max temp was 79c.
This is why this puzzles me as i suspected a heat issue.

isnt it true thAT amd processors run hotter than intel.

I regard those readings as too high. Did you use the exact method of thermal compound as given by the maker of the CPU? Removing the old compound and using the approved method is essential - there are about three ways, which should not be interchanged between CPU's.

Always pop back and let us know the outcome - thanks

Is there a fan inside the netbook? If so, does it ever run?
