My computer is a wreck?

[jimkvg at 3web.com]

I had been using Ubuntu 9.10 for quite a long time after installing it  
in a Windows XP Pro system beside Ubuntu 10.4 and I enjoyed it very  
much.  (I installed the Ubuntu 10.4, but I couldn?t get it in an  
internet connection so I resorted to 9.10, that?s why.)  I gave an  
Ubuntu 10.10 a see.  I downloaded it and burnt it to make a Live CD.   
When I restarted the PC, I noticed two CD/DVD drives?s light monitors  
flashing several times front and back and I stared at black screen.   
It didn?t even turn on, not even BIOS menu screen that I tried. I  
pushed the power button to turn PC off, waited a long while and then  
pushed it back on.  Same thing happened.  After several attempts I  
decided to turn the main PC switch on the back of the case off.  When  
I turned it back on and pushed the power button on the front.   
Nothing.  That got me wondering ... has the BIOS been shot?  or  
motherboard?  I meant ?screwed up? whatever you call it.   It left me  
staring at black screen (monitor was off) to my great dismay,  
wondering what went wrong.  Can someone please help me pinpoint  
trouble?  Should I short the CMOS jumper (pin 2 & 3) on the  
motherboard to clear it up?  I want to be completely sure I would do  
it correctly.  Any suggestion of what I could do to fix the problem?
Motherboard is msi 785GTM-E45 with AMD Athlon triple core CPU.  Two  
drives are LG SuperMulti CD/DVD.
