Noobie saying hi :)

Over the last month or so my lappy has begun locking up when under stress - running Football Manager and Chrome in background/ running a recent game (CoD: MW3). Sometimes it just happens when I'm playing a film in VLC.

The screen freezes, if sound is playing then it slows down and sounds like a growl, mouse doesn't move, caps lock/ num lock can't be pressed, processor light stops flashing.

This usually went away after waiting around a minute but a couple of times recently I've gotten a dreaded blue screen and Windows creates a dump for me - can anyone decipher these (attached) and see if they can find what my problem is?

Pentium Dual Core T4300 @ 2.10GHz
Windows 7 SP1 64 bit
ATI Mobility Radeon HD 4570

Computer has been getting incredibly hot recently too - could this just be through overheating?

Thanks for any help1

Hi taipan99,

It definately sounds to me like a heating issue. Get a can of compressed air and blow the laptop out. Make sure it is off, unplugged and have the battery out (so that you do not turn it on by accident while cleaning it). Blow the air throughout the laptop making sure that you get where the vents are really good.
If the laptop still runs hot after blowing it out, you should either take it to a shop to get it cleaned (where they would take it apart to clean properly), or you could invest in a laptop cooler.

First lets check you temperatures. Use a hardware monitoring program to check your temperatures. I always use Speedfan coz it shows fan speeds and temperatures as well, including HDD temperatures Download SpeedFan - Access temperature sensor in your computer. Core Temp should work. Get it here Core Temp - Supported processors. Also download Prime95 to stress test your CPU. You can get it from Download Prime95 27.7 Build 1 Preview / 26.6 Build 3 Free - A program designed to be used to find Mersenne Prime numbers. - Softpedia. About the dumps, I am not so good at analysing them, but this is what i got from a known debugger.

The named file (athrx.sys) is the driver for your Atheros network adapter driver and is dated Mon Oct 05 19:33:57 2009. This is an old driver. Get the latest drivers from Acer's website. If they don't have a newer version (they should), get them from Artheros, though they have an unofficial Czech website.

Thanks for this rapid support guys - I'm actually just about to go away for a few days. Will report back on Sunday!

Thanks again for everything!

Hey guys

Please find below screenshots of Coretemp and Speedfan about 10 minutes after startup with mild Internet surfing. The flames don't bode well...

I ran Prime95 but nothing seemed to happen - I selected which Stress Test but the workers didn't do anything for a few minutes, and when I ended the run it said "0 tries in 5 minutes" for both workers. Any ideas?

Have now updated my driver from the link provided - thanks! However, when I go through Device Manager and check the properties of my card it still says:

Driver Date: 21/09/2009
Driver Version:

Shouldn't I see an updated time stamp on this now?

Am heading into town tomorrow for a full clean - long overdue. (Currently living in Saigon, Vietnam - am really hoping they know the difference between cleaning and wiping the computer...)
