If you are trying to run portal 2 on your computer you might be one of the thousands of people who cannot get it to run properly. There are several things that might happen and you can put a stop to it and make it run properly.
#1- The display breaks up or freezes on you while you can hear the game carrying on.
#2- It will start and then your computer will completely freeze after a few seconds.
#3- Portal two will start and everything will keep pausing or appearing jerky like it is running in slow motion.
There are several reasons for this problem.
#1- Your graphics card is not powerful enough to run portal two. Ideally you should have a high end Nvidea or ATI graphics card. If your computer is using on board graphics it will not run. The requirements are too high and you will see and experience the issues listed above on your computer.
#2- The drivers for your graphics card need to be updated. If you are experiencing any problem and cannot run portal 2 and you are sure your graphics cards will run this software the next thing you need to check are the drivers for your card. The best way to verify this is to go to the graphics cards manufacturers site and check for the latest drivers. If this does not work try an older driver as well. Sometimes drivers are updated and introduced different issues.
#3- If you have checked hat your graphics card is fast enough and portal two will not run on your computer the next thing to check is the rest of your drivers are up to date. The most important drivers after the graphics card are for the motherboard. You should go to the website of the motherboard manufacturer and download the latest drivers and update them to resolve the issue.
#4- Ensure there is enough memory in your computer. There may be enough before portal two starts but as soon as it loads it can start eating away at the available memory. If your memory falls below the system requirements you can check this. Once you have started portal two open task manager. To do this press the CTRL-ALT-ESCAPE keys together and then go to the performance tab. Once there look under available memory. If it is too low you need to either upgrade the memory or stop processes and other programs that are consuming memory.
If you do not want to upgrade the memory the first thing you should do is to go to the windows control panel and then add and remove programs and remove any programs you do not use or need. Once you have done this stop any programs that are running at start up that you do not need. The easiest way to do this is to go to the windows startup folder on the start menu and delete any programs from there. This will stop them starting up with windows but will not remove them from your computer.
#5- If after running these steps you still find portal 2 running slow on your computer the next step is to run a system optimizer software on your computer. This will optimize your computer for peak performance and will fix file and registry errors that are slowing down your PC which you will not be aware of. To get portal 2 running properly follow these step and scan your computer with an optimizer to ensure it is running properly.
