Problem with games

I have a problem about to run Warhammer Online and Warcraft The Frozen Throne. (I have no other games installed so I do not know whether it is all games). Before I got Warhammer Online installed, it ran Warcraft THT perfect. But after I installed Warhammer Online, none of them running perfect.

The problem is that when I play a game for a short amount of time (15 minutes - about 1 hour) it starts to behave strangely. Either the screen completely strange, then restart and come up with a "blue screen", or the simply just go out of the game at 1 split second, without giving a notice on why. If it does, I must always restart before it bother running it again. It is mostly with Warhammer Online it does but have also seen it with Warcraft TFT once or twice.

It is mega-Slave and it would be nice if there were some experts who can give me good advice, or about what the problem is and how to solve it.

Can you tell us what graphic card you are using and what are the other system specification?

Ok, so here's some important information about the laptop if necessary,

Portable states Znote Zepto 3415W

Processor
Model: Intel (R) Core (TM) 2 Duo CPU T8300@2.40GHz
Speed: 2.39GHz
Type: Mobile, Dual-core

Video System
Adapter: NVIDIA GeForce 8600 GT (512MB DDR2, 475MHz/1.10GHz/2x399MHz, PCIe 1.00x16 PS3.0, VS3.0)
My graphics card and generally all the other cards said to be up-to-date by several different programs. (graphics card: 17-09-2008)
User XP

Sorry to say it, but it seems a little on either a defective graphics card or it gets too hot.

Nvidia has a problem with some of its chips, especially the mobile should be exposed. It sounds a little like you run into in. Have had a similar problem when it made the highlights in 3D. It was the graphics card was messed off.

Try to test with Atitool. It can display a small 3d window in windows and is really good to push the graphics card in the bottom. So have you as something other than just the couple of games as reference.

I've downloaded the program and tried to run it. I'm not sure that I run it right and the "Find max core" and "Finding max memory" over but by core began my PC to flash crazy fast so it was just before we got sore eyes and were needed to extinguish it in the rough way to stop it. On the other went on simple just in black and so I did not tried with it because it is not particularly good for the PC by closing this down.

Can I get a little help or an idea of what I should / could do?

You've actually done more than necessary. That you have tried to find the maximum of clock on your computer. A funny enough exercise, but not exactly what I had in mind.

Now, I have not just installed the program, but all you can do that to beat the small 3D window and then just leave it. You may use this feature to look for artifacts (the small graphics errors, as I think you see). It makes no more pressure on the computer than it is designed for. If you find the same kinds of errors by this procedure, it suggests much that something is wrong with your computer.

If it works here, you should perhaps consider a reinstallation.

I've tried a lot of different things since last time again.

I have had vista now and tested whether it should solve the problem because my PC is set up to the vista. But no: (When I switched to xp I have also tried to reinstall it if it solves but it does not)

However, I have measured the temperature on my PC and when no programs are open meter on my PC to 6-12 degrees around .... Synthesizer it sounds a little too low. When I play on to the max up to 55 degrees and it is also low to the other, I think ...?? So it may well be that the sensor is not functioning properly ... (spent Core temp and Speedfan)

Since I have switched to vista, I have also remembered to get all driver updates but I also encountered a problem - I actually have had with xp and every time I had to install the graphics driver.

I can get drivers come from the manufacturer of my motherboard but all other pages do not bother it. And come from Nvidia also not bother. Synthesizer it sounds a little strange but not certain that it has something to do with the problem. When I phoned in to Zepto support, there were just a lot of radio music played in laaaaang time then dropped it to last. Would be nice to know what I could do.

Recently here I went into the blue screen once again as all the other times. But this time I had nothing but firefox and msn open. So it can hardly be played? thinking too little of it could be the sound card because I have heard music some times but now can not remember whether I had called on every time it crashed...
