Sorry forgot to post, I had already verified from command line, ive only got 5 games in rom folder as a test at the moment, but they are all working fine using command line in dos. I tried running the frontend in dos too, which loads up fine (minus the control usb controller, which is fine ,as you pointed out doesnt work in pure dos), tried choosing game, same sort of thing happens, frontend quits to dos prompt, no error messages that I can see.
With regard to the monitor, the desktop is awful, its very blocky, I tried installing the monitor drivers again, but to no avail, this was an old pc of my parents, but I seem to remember the desktop not looking that bad. But ill check out that link you gave me, once again thank you.
