Why does my computer restart without warning when im playing games?

It could be your power supply is not strong enough or going bad. It could also be memory (RAM) errors or not enough RAM. It could also be your video card doesn't have enough video memory to handle the games. Make sure your computer exceeds the minimum requirements for the games you're playing & make sure you close other programs so you free up some RAM for the games. There's really no way for anyone to know because you don't give any specifics about what your hardware is or what games you're playing.

this is due to the fact that u have 2 many things running which results in ure computer overheating. if u go to Run then type in 'msconfig', and then a dialogue box should appear, which tells u all the programs that are running on ure computer and some u probably dont know about. untick the ones u think that are unnessery. this should prevent restarting.

check it for viruses

Usually when that happens it means your computer has decided to restart due to an error. If you visit the website of the makers of the game they would be able to advise you and send an email with step by step instructions you can try. I have done this many times and its usually changing the settings for acceleration in the display propertys>settings>advanced section.

Could be a problem with your drivers, check you have the latest ones for your sound and graphics cards...

It might be a virus. I know some computers that constanly restart when there's a virus. Run a virus program to see if your computer is infected and needs a vaccine.

yourr playing the gamess for too long either the games are to strong for your computer are your just burning up your cpu... these games probably are overloading you cpu with operations so it just restarts..

could be dogy ram(or somethin simple lose plug) if the ram is dogy then it can cause programs to carsh causeing the pc to reastart
