Start > Run > MSCONFIG\n\nClick the "Startup" tab.  Be very cautious when deselecting programs; you do not want to stop something from running that you need for the system to run.

If you have Windows, do this  Start -> Run -> type in msconfig press ok\n\nIn this command go to startup and all the boxes that are checked, uncheck all the ones you DONT need when you start the PC up, all these programs run when you start the PC and take up processor power.  Just be careful, if it is a Microsoft one, or a System32 one dont uncheck it, the system needs those to run.

Make sure that nothing is impeding the ability of your system to cool itself.  Putting the back of it just one inch from the wall is probably going to let it overheat quickly.  If you have software that lets you read the system's internal thermometers, you might want to check them.\n\nIf the computer is further than an inch away but still pretty close, try putting it at an angle to the wall, so the hot hair does not largely bounce back into the computer.\n\nSee if you have the latest drivers for your video card, and for MS-Windows.  Out of date drivers, especially graphics ones, can cause serious problems.  On MS-Windows, graphics is done right in the core - the "kernel" of the OS.\n\nThe problem with that is, flakey graphics drivers can pretty much crash your machine.  Do a lot of graphics, you increase the risk and decrease the time that it will take before this happens.\n\nCheck your installed version of DirectX versus the one required by the game(s).\n\nAnother possibility is that maybe you have the bad capacitors problem.\n\nIf you want to determine if it is a software vs. hardware/firmware problem, set up your PC to run Linux.  You can either install Linux in a "dual-boot" configuration, or you can get a Linux Live CD for some popular distribution (Ubuntu, Fedora, etc.)\n\nThen just run some Open/GL 3D graphics benchmarking utilities or games.  If it crashes after 10 minutes, that points to your graphics card itself, or its firmware.\n\nIf it continues to run then that points to something on the MS-Windows operating system (the OS, DirectX, or video device driver) being the problem.  If that is the case, then you might want to address those to make sure they are up-to-date.  Or, you could simply get lots of free, open source games on LInux and have fun there.\n\nWhen checking for up to date drivers, don't just rely on MS Windows Update.  Check the manufacturer's website.

Unplug the power cord from the back of the PC, leave it unplugged for 30 seconds.  Plug it back in and turn on the PC, then turn off power save and hibernate.\n\nGood luck HTH!

Suggestions Galore\n---------------------------\n\n1. Go to run, type msconfig and press Enter. Select the startup tab and deselect all the checkboxes expect your anti-virus.\n\n2. After some monthes of usage, your computer's regestry gets fragmented just like your hard drive. So install a Registry cleaner (e.g. Winaso Registry Optimizer). \n\n3. Go to My Computer properties, select the advanced tab. Select visual settings and uncheck as many checkboxes as possible.\n\n4. Install a hard drive cleaner (e.g. Easy Cleaner).\n\n5. Update your system memory.\n\n6. Whenever you feel the PC is running slow, open the task manager and close useless processes manually or you can install a process cleaner.\n\n7. Run a virus and spyware scan. These slow the PC down.\n\n8. Install a system Optimizer.

For desktop pc better performance, I suggest you set your desktop background/wallpaper and screensaver to "none",   then go to control panel, system, advanced, performance, settings, check 'adjust for best performance'. and  right click on desktop, click properties, click 'appearance', choose ' windows classic style'.\n      Then Start/Control Panel/Display/display properties/screensaver/monitor power/power schemes/settings/turn off monitor after 10 minutes, and set the next 2 drop down boxes (  1.  Turn off Hard Disks,  and 2. System Standby) to "never"/apply/ok/ok.\n Then Start/Control Panel/system/advanced tab/performance/settings/'adjust for best performance/apply/ok/ok\n     Then Start/Control Panel/Display/display properties/screensaver/monitor power/hibernate/take check mark out of "Enable hibernation"/apply/ok/ok.\nIf I'm going to be away from the pc for more than an hour, then after shutting it down properly, I unplug it.\n\n\n      For security/safety purposes,  to make sure you are not getting a spoofed webpage, right-click desktop/properties/display properties/appeareance/color scheme/olive green/apply/ok/ok ,  or  go to Start/Control Panel/Display/display properties/appearence/color scheme/ eggplant or wheat/apply/ok/ok. \n  Then if you click onto a webpage, and it comes up in the MS default blue, then you will know you are on a fake/spoofed page, and you should close out immediatly, and run a scan for infections.       Right-click desktop/properties/display properties/appeareance/color scheme/eggplant or wheat/apply/ok/ok
