Mac Pro G5 won't recognize new monitor - help is appreciated!

New guy, new troubles. I am not a 100% sure if this is the right place to post my issue - if it's not, I would be dearly grateful for an admin to move this post elsewhere.
Anyway, going on to the issue. I just got a Mac Pro G5 from 2005, and when I tested it, it worked fine. But when I went away and bought a new monitor, (A V7) the screen would just blur in several funny colours. (Mostly white and blue)
I've tried everything that I could possibly come up with. Bought a new cable AND a new cable adapter, tried with a different monitor, (ViewSonic) adjusted screen resolution in every possible way. I have two clues to go on; Whenever I put up a screen resolution on a higher scale (Like 1270x780 or something like that) the screen would turn black and display "out of range". It's when I tried a lower screen resolution that the screen would display funny colours. Clue No. 2 is that I actually did see the Apple Logo a brief time during a startup after I simply blowed my graphics card. My heart lept, and I quickly reached for a vaccum cleaner to clean up the whole Mac internals. (It was quite dusty) But after that, still just funny colours.
Also, whenever I start up my Mac, the fan would immediately set on full throttle - You know, the Mac Pro fans that sound like jet engines. Every time. Is that related to my problem somehow?
I feel myself stuck, since I can't really enter the Mac to try the "find new monitor" option, since I simply can't see. I've tried safe mode too.. won't happen a thing.
This has been quite a blow for me, since I've really been looking forward to this.
Any help is deeply appreciated. Thanks.

G'day and welcome to the forums.
Well if it is 2005, it is a G5 PowerPC and not a Mac Pro. Mac Pros only come with Intel processors. Sounds like the graphics card is shot. Is the card an AGP or PCI-E card? Also Mac Pros are silent and if the G5 roars you may well have a dying logic board. If it is the 2.5GHz Dual Core, they are liquid cooled, and a leak getting the coolant into the processors can also cause these problems.Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
