Default [Q] Assistance with rooting HTC Desire?

Hi there guys, I'm new to this place so I'm not entirely sure if this is the right area to post, hope it is XD

So basically, I have my HTC Desire, which I am unable to root. When I try rooting via Revoked, it gets to the screen where it says 'Make sure drivers are installed', but the thing is, when I follow tutorials for installing the drivers (Install HTC Sync, uninstall, connect with the Android 1.0 and update) the problem is, I do get Android 1.0, but I can't update it, it is just grayed out. But then Windows Update does something and it changes to HTC Serial Interface (COM4/5)

So in another tutorial I read I had to unlock bootloader, so I jumped on HTCDev and got the file and then it updated my HBoot to 1.03.0003, which apparently is not something that works or something? (I'm not fully sure, first time rooting D: ) and then I read I had to downgrade, but when I downgrade with the RUU it just won't work, it says to make sure it's connected even though it is. I am fully stuck, and really don't know what to do!

The guides I used (I can't find em all) are:

If I could get some guidance, maybe in the form of Teamviewer or something, I would be hugely grateful! (and if you could tell me how to increase storage space etc that would be AMAZING)
