I didnt get what do u mean by digital DVI output
no additional cables are needed for hd 4670 from psu
it directly uses DVI ti VGA connector on which monitors cable is attached and it is inserted in the graphis card

There are commonly two DVI outputs. One is for digital only. The other is for either digital or analog. That is the output that you want for your DVI/VGA adapter.

If you graphics card has a D-SUB output (for VGA) use that output without the adapter.

Don't think about using that PSU

https://community.newegg.com/eggxpert/computer_hardware...
Tier 5 power supplies are NOT RECOMMENDED. If you have one, you should strongly consider replacing it ASAP. These can damage your computer, and often cannot put out the power that they're rated for.

OK, then we have eliminated that possibility (wrong DVI port). Does your motherboard have graphics outputs that you can try to eliminate the graphics card?

Another option would be trying your monitor on another computer to eliminate the monitor itself.

Does the all of the fans spin? Do you have another working power supply that you can switch out the current PSU. Do you have a multimeter so you can check the power supply?

With a system this old it could latterly be any of these.
