no beep codes? no dos looking screen? so no bios. Well, easiest thing is to try and reseat the vid card. when putting back in make sure its in GOOD. no contact should show. if nothing, then I would remove everything but the HDD and vid card (and of course the mem and processor). bare bones, esentially. no sound card, cdrom, nothing. Then try and boot. If it boots put everything back in one at a time with the cdrom being the last. If it works after all being put back in, may of been a conflict or a device not seated right. if it stops after putting a certain device in we've found the culprit and can go from there.
If you argue with an idiot he will drag you down to his level and beat you with experience.
