Question about Dell OptiPlex GX520 PC Desktop
MY SELF DINESH SONI FROM sECURE METERS LTD,UDAIPUR,RAJASTHAN-INDIA
A surge protector stops power surges from eskom etc. from fryin your mother board and power supply. when the power goes off sometimes its just a phase . when all phases are off and the power comes back to all Phases instantly at a strong output this can fry your mother board or damage your power supply . surge protector keeps the power at one level even if it isnt , make sense? Also see UPS.Lightning can do the same effect too

The hardware that you are trying to access is damaged or failing.
The device drivers for the hardware are faulty or incompatible. There is a connection problem such as a bad cable
click start control panel administration tools computer management device manager scroll through all of your devices
if you see a yellow question or exclamation mark ? ! or a red X you will need to update the drivers for this device right click select update driver/reinstall driver
if you can see your usb device but its not working scroll to Ports(Com&Ltd) right click to update driver
if you computer came with a motherboard disk the drivers could be on it
One bad lead can cause a computer to continue on a cycle to shutdown or fail to detect a hard drive
Test all leads that attach to your hard drive including electrical extensions IDE,SATA
the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a
secure connection and are not faulty or just replace them they could be faulty if its a flat 40pin ide
this will be the first to fail
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions
or just replace them they could be faulty a computer needs power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error
hope this helps
