I have a Dell Dimension E520 2.93GHz, 1GB DDR2 667MHz ram, 250GB HDD. I recently upgraded to 4GB Mushkin DDR2 800MHz ram, Antec earthwatts 500 watt PSU,Gigabyte GT 240 1GB video card and added a second 500GB HDD. After everything was installed I booted the system and after about 25 to 30 seconds it re-booted then it would just shut off. I tried eliminating the new components one by one with the same results. I finally went back to the original memory and the original video card and kept the power supply and second hard drive in the system. Now it runs ok until I log out of my game it will reboot.(Need for speed world) I also start transfering data from the 250 HDD to the 500HDD and it reboots or shuts down. Im beginning to think its a heat issue because all of the components are compatible. There is no fan on PSU and the HDD's are right next to each other about a 1/4 inch apart. I am a intermediate tech and Ive never seen this before. Anyone have any Ideas?
