Yes, the only and infact proper way in this sorta situation is trying with another working monitor. If this new working monitor works Ok with the system, then your original monitor maybe damaged. If it gives the same charecterstic, its probably your video card, since you can hear xps startup sound, other componenets should be OK.
OR, you may try this non-working(fo the time being) monitor on another working system.
Plzz do that and post back.
In the land of Seatle, by the fires of Microsoft, the dark lord Bill Gates forged in, secret, a master OS, to controll all PCs.
And into this OS he put his greed, his malice and his will to dominate all computer media.
One OS to rule 'em all.
