compaq presario SR1922IL. Want to change its desktop nd keyboard plz tell the charge for it

[Rohit_B123]

I want to replace keyboard and desktop of my pc. I need a guidance regarding cost to get my pc in workable condition.. is there is any changes i need to do in my CPU?

Since the Compaq Presario SR1931IL was brought to market fourteen years ago, all of the upgrades, except for the keyboard, will come from the second hand market.

Keyboard: any USB keyboard.

Desktop? I have no idea as to what you mean. Your  Compaq Presario SR1922IL PC is the desktop.  If you meant to say monitor or display, then any VGA display will work. Your PC has only analog VGA output for video, so HDMI displays will not be compatible. 

Best price will be dependent on your own skill in bartering. 

Motherboard: Asterope-GL8E
