Acer Aspire M5800/M3800 crashes when playing games

[myloo]

My stationary Acer crashes when I play games for like 3 mins(ex. The Sims 3, Civilization V etc.) It kind of goes to digital saving mode, and its still on, but screen is black. And if I had music it would lagg.

This started a half year ago, when I updated the graphics card (NVIDIA). I did the auto-detect graphic card on NVIDIAs site and downloaded the recommended one. But then started the troubles.

Iv'e tried these thing:

- Restored computer to factory settings
- Clean the fan inside computer (due to overheat, but don't know if that's the problem)

Here are the computer specs:

Operating system: Windows 7 Home Premium 64-bit (6.1 build 7601)
System manufacturer: Acer
system model: Aspire M5800/M3800
BIOS: Default system BIOS
Processor: Intel Core 2 Quad CPU q8300 2.50GHz (4CPUs), ~2.5GHz
Memory: 6144MB RAM
Video card: NVIDIA GeForce GT 320


Does anyone know what the problem might be ? I'm not so good w computers..

Thanks!

On your laptop go to google and type can I run it then click on link in there type in what game crashes the most or look for it in the drop down menu then it will run a test for 1 min then it will let you know if it all passes or if it fails on gpu etc

You should revert back to here:

and download and install the Nvidia video driver for your desktop computer

With my m5800, I had to do 2 things to keep it happy & running well.
1. Upgrade to a larger Power Supply that has some elbow room, it'll run cooler and more efficiently than one running at the top of it's capacity. Efficiency Certification is a good thing with them, optionally, voltage regulation is great too.
2. Upgrade to a better Nvidia card with a minimum of 1gb ram, offloading process from the cpu will help the whole system and extend the life of your computer.

On those 2 points, I put in a psu around 700 watts (note; continuous limit ratings may be better than simple top output ratings on choosing a psu). I'm on my 2nd nVidia card and now running a GeForce GTX 550 Ti based card, works great.) Could have gone for more but, still have a budget to work within.

I hope this helps anyone else out there wanting to keep from having to replace their system, especially since the M5800 is still not a bad computer for Windows 7 .. personaly not a win8 fan but that's just me.
