Hi

 

You cannot get video using either the ATI graphics card or onboard graphics.

 

Is this correct?

 

This suggests some other piece of hardware has failed.

 

You can start troubleshooting other components. Are you okay with working inside the chassis?

 

Your PC is about seven years old. Do you routinely clean the internals with compressed air?

 

Possible components which may have failed are as follows:

 

1. Power Supply

 

2. Bad RAM or RAM slot on the motherboard

 

3. Motherboard failure (this could be any number of integrated components which may have failed). Take a good look at the motherboard for any signs of thermal damage.

 

4. Attached component short such as a CD/DVD drive or USB card reader.

 

5. CPU . Motherboards fail at a much higher frequency.

 

You will have to swap in known good components, one at a time to find the culprit.

 

Disconnect all peripherals such as Printers, or any other USB device. Only connect a monitor.

 

First replace the CR2032 MB battery. Make sure the system is clean (fans and heatsinks).

 

I usually then swap in a good power supply.

 

Then pull all RAM to see if you can get an error message at startup.

 

Disconnect the HDD, CD/DVD, USB card reader. You should get a non system disk error if you get video.

 

No video is leading to a MB failure.

 

Easier (and less expensive) to have a local PC technician take a look.

 

Tom
