+ 0 Votes Heat or RAM IcebergTitanic 2 years ago First two things I would look at are: Is your video card overheating? Is the fan working properly, and is the computer arranged in such a way as to allow good airflow? Since you state that this happens in video games, that makes the video card the first suspect, since the OS itself generally doesn't tax the video card too much. Secondly, check that you're not running out of RAM. If your computer has to start shifting to paging (where it uses the hard disk as a temporary "RAM") then you're going to notice very severe performance degradation. You can turn on the Task manager, and minimize it before starting the game. Once it slows down, exit the game and look at the task manager performance tab. + 0 Votes Reponse To Answer seanferd 2 years ago Don't forget: Never use a vacuum cleaner! Canned air or one of those little computer/camera vacs if you don't **** it out with your own lungs or use a swab. + 0 Votes Multiple copies of svchost is normal robo_dev 2 years ago each copy of svchost takes care of some processes, services, or DLLs, so it's normal to have a few of those open. I would make sure there is no heavy background program or process that's sucking up all your processor utilization, such as an AV scan, a windows update, or a rootkit phoning home. Some programs like Adobe Flash or Java can real hose things when there's an update pending. One simple test is if the game is a standalone game, unplug the LAN connection; that will stop anything from going online and updating. More specifically, do a netstat -an from the command prompt to see what network connections are being made. Also a netstat -b will show you which processes are making what connections to what other hosts....this can show you if something odd is going on. + 0 Votes I'll keep an eye out... wompai 2 years ago ... for these things. I think its the GPU overheating but I'm not sure... It's temperature hardly gets above 80C which is pretty normal for notebooks... + 0 Votes overheating wompai 2 years ago I think its overheating bevause the RAM usage does not get above 70%. I'll check wether I can increase airflow... + 0 Votes I do have dedicated video ram wompai Updated - 2 years ago My laptop has an Nvidia GeForce GT 420M videocard with 1024 MB of dedicated RAM not shared. It is perfectly fit for gaming. Check this:http://www.notebookcheck.net/NVIDIA-GeForce-GT-420M.35837.0.html The high temperatures may just be the reason why it decreases in performance. The temperatures in idle already are close to 60C so I don't think getting to 80C matters that much and btw I said that it hardly gets above 80C. I meant that my card occasionally reaches that temperature. Normal gaming temperature is around 70C. + 0 Votes If... wompai 2 years ago .. I open my laptop will it void my warranty? Because maybe when I can open it I can clean all the dust and look at the fan, maybe after a good cleanup, it will perform better. Thanks for the help on this topic, you, once again, helped me enormously.
