Too good to be true, I knew it

Less than 24 hrs. My happy times is just too good to be true, wanted to transfer a file to my flashdrive before going out, turn on the computer, then just let it boot; so i just walked around, went down stairs then came in to the pc room again, WHAT IT DIDN'T BOOT. Tried 3x again and again, same thing.

PLEASE INSERT BOOT DISK AND PRESS ENTER

started googling and trying to find the answer; found out that there's maybe 3 possibilities for it, boot system problem, cmos battery is dead and the hdd is corrupted.Hopefully it just the cmos battery

I miss the desktop, it helped me and my family a lot; everything is a breeze on a desktop, although it was over than 8 years of age. But still i miss it.WHAAAAA!

Just that is what i want too say no mood oredi...
