Question about Dell PC Desktops
My Dell Dimension E510 won't power up with the on/off switch. When I unplug for 30 to 60 seconds, then plug it back up, the CPU comes on for about 2 seconds, then turns back off. The monitor only shows a rev number.
It's the processor or power supply. I cant be sure of which without checking it.
Check the fan over the processor heat sink to make sure its working cause it could mean that the processor is overheating If the fan turns and then it cuts off this could meant that the processor is dead. or the bios is corrupted. Try flashing the bios, there is a battery on the main boad, remove it. unplug the system first... when the battery is out press and hold the power button for 10 seconds then release. put the battery back in and try to turn it on..
If that fails then try a new power supply or one from another system to to check if the power supply is fine. YOu can aslo bridge the green and any black wire from the power supply's mainboard connector to see if the power supply runs. If all this fails then you may need to replace your processor,, I';d also recommend changing the power supply as well.
