I think this is the reason. Non Toshiba drivers don’t have an overheat protection and so the graphic card can be damaged. It’s recommended to use the drivers from the Toshiba website because with these drivers you are on the safely side.

Check the Toshiba website for the newest drivers and I think the problem will be solved:

I’m really surprised that you try to play GTA 4 on this notebook.
Your graphic card 7900GS and this card fulfilled only the minimum system requirements of the game.
To be honest I have this game too and this graphic card is not fast enough for the game. Therefore you need at least a Geforce 9600 because the system requirements of the manufacture are a joke.

However, try to update the BIOS but I doubt that this will solve the problem. The problem is definitively the non Toshiba graphic driver.

I found out what the problem is with the new BIOS. There are some temperature borders the bios wants to prevent to reach. I controlled the temperature during stresstest and found out the screen stops for 1 second at 76°C, at 84°C and at 93°C. While the screen is stopped the temperatur falls for 1-3°C but then rises fast to the border again. So there are regular stops between heating and cooling down. If the border is crossed the pc works normal until the next spot is reached. I flashed to my old BIOS because this solution of preventing an overheating isn't quite intelligent.

Thx for tryin to help me
No thx to Toshiba, the support convinced me to never buy a Toshiba again

I have the same laptop.. and they sold me saying that this laptop supports 64 bit operating system in the future... and I bought it believing that... and guess what... I was able to intall windows 7 64 bit operating system... but the mainboard was able to see my 4gb ram but would only accept 3gb of it... I almost begged toshiba service explaning the situation.. they told me that Toshiba does not support 64 bit operating system for this laptop...

There are older laptops in the market where you can put 4gb rams on them and they accept them.. they do not even have better graphics card on them than P100.

and the second issue... toshiba can not produce proper updates... as in the case of my sound card on P100....Aparently there is an update for Conexant sound driver by toshiba.. but as soon as I installed that driver... the computer went quite.... I took it to the service to have that driver installed with its original operating system (win vista home edition 32 bit)... and it is the same result... the computer was quite.... and the toshiba service advised me not to install their updated sound driver and carry on using the old one!!!...

I have been using Toshiba laptops for very long time now.. my first laptop is a Toshiba P20.... even that laptop has only been good for a short while (maybe 1 year).. then its Fxgo 5200 sound card was almost inadequate for anything... It was not even enought to open Google earth a year later....

You are right about Toshiba... they insult the intelligence of their customers... Their laptops has no continuity as the other companies laptops such as hp...etc.... They quickly quit supporting their products and producing drivers for them... They make colourful laptops and they take your money... and when it comes to supporting their products... they leave you in mess...

Btw, the problem of stuttering video, scratchy audio, hissy ripping (they're all methods of streaming large amounts of data) is not a Toshiba one it's a windows design problem in how the driver system is implemented. Windows is not a real-time operating system. You just have to know how to tweak it right so it works most of the time.

The computers where you think they don't have a problem it's not because it's not there it's just because it's not obvious enough.

Then after getting rid of the high DPC's there is a secondary issue that you will hit a limit on the CPU & GPU in running certain games and their frame rate will drop depending on the game developers choice of implementation (that's where you need to change the settings), but you can run tools to check where your CPU/GPU max out at which can be a basic guide, e.g. 3DMark11 or 3DVantage.

DPC latency is a much bigger problem.

Now my laptop is low DPC latency I can run 3D games with no glitches even on my i3-380m with inbuilt HD graphics. You have nVidia what are you complaining about.

In my honest opinion the problem is not the BIOS.
It’s your graphic card driver that I already said but I think you ignore it.
Try the new BIOS with the Toshiba graphic driver and you will see it works.
