• Satellite C660-184 freezes at random times while playing a game.

  Laptop freezes at random times while playing Football Manager 2011. The game is not graphics intensive and worked for about a month with no problems, just recently it started to freeze, and the only thing I can do is to turn off my laptop by the power button.

  I have a

  Satellite C660-184
  Windows® 7 Home Premium 64-bit authentic (pre-installed, Toshiba-HDD recovery)
  -Intel® Core i3 - 380 M processor
  SuperMulti DVD + r (Double Layer)
  -RAM (1066 MHZ) DDR3 4096 MB (2048 + 2048)
  -39.6 cm (15.6 ") TruBrite® HD (1366 x 768) high brightness display with LED back light with aspect ratio 16:9
  -Intel HD Graphics, display memory: 1 696 MB

  My graphics driver is up to date, said my last is 28/07/2010.

  I am at a loss to explain what is happening.

  Help and advice would be greatly appreciated.

  Hey Buddy,

  > The game is not graphics intensive and worked for about a month without any problems, has recently started to freeze
  This could mean that the laptop is overheating
  The reason for overheating is the dust that blocks the fan for laptop gets hotter

  I recommend to clean using a jet of compressed air to blow the dust from the cooling fans. You can do it without disassembling the computer so it is very easy and takes only 5 minutes.
  Just remove the battery and unplug the AC adapter before doing this.

  For example I clean my laptop every 4 months because a lot of dust is coming so it s worth it.

• Unexpected freezing problems randomly on Gears of War (PC)

  Hello

  I have a computer with Vista 32 installed. The main components of the system are;
  -Core two 7500 Due (2.93 Ghz)
  -6 GB of Ram
  -ATI 3870 GPU (Catalyst installed 9.9)

  In fact, game performance is perfect, but I have the problem of unexpected freeze at random during the game Gears of War. I have to press ctrl + alt + delete to return to Vista

  At first, I thought that it is a memory problem. I used to have 2 x ATI 3870 in cross fire mode and 2046 MB physical memory.  To increase the physical memory, I removed one of the card and now I see 3070 MB of physical memory. Then I re-load the game to check the difference, but after 45 minutes the game freezes up to play again. Here are the details;
  -At the start of the game, I have used physical memory 59%
  -During the game, I have used physical memory 67%
  -When the game freeze-up, I have 67 physical memory %

  I guess that this is unrelated to the memory. In any case, when I checked the performance of the processor to freeze-up, I can see 100% full load. In my view, that the causes of the problem. I suppose that there is something on the game code that causes my charge of 100% of the CPU and no response.
  No idea what can be the problem?

  Furthermore, I have similar problems on other games such as Crysis and Red Faction. For example, when I play Crysis on win XP with DirectX 9.0 c, with no no problems, but on Vista with Directx10, Yes. I think that there are some questions on Directx10.

  Could you please help?

  Thank you

  If you need more specific information just tell me and I'll try to get it for you

  first look at the Task Manager Control Panel and to ensure there are no tasks entered and run in the background.

  -

  then consider the possibility that your anti-malware program may not be set up and that's all that scanning actively all the time, including the frequent updates of the registry hive.  You can temporarily turn off and see if that helps.

  -

  Then, see about turning off your index for a few days service help.  go to administrative tools > services > service index.  Sometimes, the indexing service may be index records wrong or it's indexing your anti virus program is running.

  -

  then see if the activity ceases to disconnect your computer from the internet.  Perhaps, there are programs to connect to the net in the background and without your knowledge.

• Why my Windows 7 crash/freeze during playback of ANY video

  lets see someone can get their head around it because it's driving me around the bend.

  Then... I have a media Center PC connected to my TV high definition VGA cable. I ran the XP PC for a long time, but last December, I've upgraded to Windows 7 with my laptop.

  Mark 5 months of use of seamless media and integration of network - it worked like a dream and I played HD and SD content with ease.

  About two weeks ago, I was watching a HD ".mkv" file in Windows Media Center and Gardner ten minutes in the video, the video just file - both video and audio. I had to turn off and restart the machine and started again the video file. Five minutes after the restart the video file, it hung again (not in the same place in the video). Then, I went and watched the video on my laptop , where it worked fine.

  A few days after that (first time I had used it again since he hung up), I started to look at a folder ".avi" of sustainable development. About 1 minute in the video the screen lost its signal (come the little built in the chart 'no signal') and after 15 seconds following the audio cut out as well.

  This latter behavior that happens now whenever I try to watch any kind of video SD or HD of any file extension. This problem is also independent of what player I use (windows media Center) and windows media player classic after a minute or if the display turns off and audio quickly follows.

  Suffice it to say, I was a little annoyed but knowing a little about good the computers that I decided to try to solve the problem by taking the following measures.

  (1) I uninstalled all my codecs and reinstalled the latest version of the K-Lite Codec pack. The latest version has support for windows 7 so I doubt that it is a problem of compatibility here. After doing this the problem persist, exactly the same as before.

  (2) I checked the date of drivers for my card (nVidia MSI 6200) and saw that they were dated from September 2009. I went to the site of nVidia and found the latest drivers win7 dated April 2010 - I have installed these but the problem is still there.

  (3) I thought, maybe it's a problem with the hardware of videocard real itself. When I built my machine, the parts supplier accidentally sent me two of the same video card so I swapped the existing for a version brand new brand of the same card. The problem is always EXACTLY the same.

  So yes - I am quite annoyed and frustrated right now because I have absolutely no idea what is wrong with the machine and how she went from work not work almost from one day to the next.

  I would add also that the screen is perfect when you are doing something else on the computer - I can surf, play youtube videos, listening to music etc, and it's absolutely no problem.

  Put on a video, and it cancels to display, as I explained.

  WHY?

  halp.

• Satellite M30: random characters came on the screen even when installing

  Hello

  I have problems with my Satellite M30. It shows random characters or signs on the image. Other than this computer works well. I thought it could be virus, because I can see the Toshiba and the fine Centrino Logo, it starts happening during Windows loading.

  So I reinstalled it but random characters came on the screen even when installing. If anyone can advise what this could be?

  My thoughts are either bad graphics card or a Ribbon of a cable LCD screen mobo.

  For me it also looks like a GPU malfunction... what you is to connect the external monitor to the laptop. If the same strange signs, characters will be visible on the second screen while the GPU is defective...

  Well, it would be the worst case, because the whole motherboard must be replaced in case of malfunction of a GPU chip...
