Was playing tonight and the computer made a weird noise like kind of a bang then a pffft sound then went dead.  We had a lightning storm last night and the power went out a time or two.  Alas no surge protector.
So, I had an older computer and voila, same wattage power supply so I swapped it out.  Now, when I booted it up, it works fine except it wont find drive a.  Is there a particular cable that should go first to it or do I need to hook up another cable or what?  right now there is only the plug with the 4 pin end in each of the cd, dvd and a drive, along with the wide floppy 2 inch wide bundle that goes from motherboard to the drives.  Did my drive a go bad also when power supply went out?
Also, if worst comes to worst, how good of a new computer should I get?  I have a 2.53 gig now with 1 gig ram and a 64 meg vid card, mx 440 now.  
Thanks very much if you can help me out.
