There are no "5 beeps" after turning on. Also, no reaction on FN key and power cable. If i put out RAM, there gonna be 5 beeps. But when i reconnect everything and push power button - only black sreen and continious "puff", not beeps, from loudspeakers.

Dear forum-members, I have a problem and I desperately need your help. After making some changes in unlocked BIOS my computer (M18X R1) refused to boot. Now i have black screen from the start. "Alienware" sign glows, fans turns on and nothing else happens. The main question is - How can I reset BIOS if "blind flash" didn't work (tried multiple times - fans start run at full speed, but no beeps after that). Removing CPU won't work either. P.S. Please, forgive me for my bad, in terms of English grammar, post.
