Dell Optiplex 320 - always have to switch offf and on before rebooting

[Jegajothy]

I have a Dell Optiplex 320, and my OS is Windows 7 which is an upgrade from my win exp prof. Also I have service pack 2 installed. Memory has been upgraded to 4 gigs because of Dell support suggested that the old memory were faulty. Bios has been upgraded to the latest, I think 1.1.12 and also the chipset too has been upgraded.

But always when I am done I have to follow the following sequencing of powering off.

 

I have to unplug the cable, and then hold down the power button for 5 seconds. To power on and reboot, I have to plug the power cable, and then press the power button.

If I do not follow this method as suggested by Support, my Dell hangs up at 4/5th of the way and stays there.

But even following this process is not a sure thing as i sometimes have to do it about 2 to 3 times before the Dell can boot successfully.

This Dell was a gift when my old Gateway pc dropped dead on me, so I am new to the Dell environment.

Can anyone please suggest any fix for this problem. Thanks.

do you have status lights on the front? if so what lights are lit up during a reboot?

Run the Dell Diagnostics for this model: - if it is hardware this may pinpoint the problem..

Is the machine under warranty? If so, I would be demanding that Dell take the appropriate measures to repair the machine.
