Hello my computer crashes few minutes in games I don't know why and this is getting really annoying and sometimes it will make a beep sound and restart.
CPU Intel core i5 3330 3.0 GHZ
Ram DDR3 8 GB 665.4 MHz its from corsair part number is cmx8gx3m1a1333c9 if that helps.
Grapics card GTX 650 1 GB
Oh and my computer brand is Dell inspiron 660. Hard drive is 1 TB don't know speed its the stock dell one. I have windows 10. I have windows 7 CD should I down grade?
 
Solution
So you bought a dell 660. Then you decided to upgrade the video card, am I right. But you didn't change the PSU, so now you have a 300W psu, a GPU which requires 400W and you haven't plugged a 6pin power connector to the GTX 650. Am I right?
