by process of elimination, try unplugging your monitor from your computer. turn it on, the built in self test should run. it will give you color coded boxes like red green, blue etc.. and would tell you no signal. if you cant see any lines during the buit in self test, then is the video card thats busted...
check to see your direct x status by typung dxdiag in run and test if they all pass then I would check the card wattage rating and you max power supply load the card may be to much for your power supply
Does the Verical line on the monitor also come when the monitor is unplugged from teh system. If yes the problem is with the monitor. If no the problem is with the video card. The computer maufacturer may have given you cds to run diagnostics on the card. Eg on dell system , you need to press the f12 key 5 times after you turn the system on , to run the diags
SINCE THIS WAS AN INTERMITTENT PROBLEM ARE YOU GOING TO BE THE ONE DOING THE REPAIR,IF SO I WOULD CHECK EVERY CONNECTION IN IT.I HAD A SIMILAR PROBLEM AND IT TURNED OUT TO BE THE CONNECTIONS THAT WENT TO THE MONITOR.IT SEEMS TO BE A GRAPHIC CARD PROBLEM BUT I WOULD NOT CHANGE THE GRAPHICS CARD UNTIL I CHECKED ALL CONNECTIONS.AND SINCE YOU HOOKED IT TO ANOTHER MONITOR I WOULD SAY IT IS THE GRAPHICS CARD.I HAVE FOUND LOT OF PARTS AND STUFF ON EBAY.THEY ARE USUALLY THE LOWEST PRICES I CAN FIND. GOOD DAY KZ
