Weird thing happened to me today.  By weird, I mean, I can't really explain. It started when I got the lamp from my brother & accidentally bumped my computer with it.  *poof* There monitor didn't get any signal any more but the power was still on.  I tried to reboot my computer and got stuck with this error:

PXE-E16: Media test failure, check cable PXE-MOF [...] Invalid partition table

The first thing I noticed was the "Invalid partition table" part.  This got me worried because I got this error once and ended up having to reformat one of my hard drives. I'm not really a hardware person but being me, I tried to fix it anyway. First thing I did was to open up the case and check the cables.  Nothing really changed then, except that there was less dust in it now.  I wasn't able to clean it much before so dust bunnies were everywhere!  I tried booting it up but the problem was still there.  While doing this, I discovered that one of my CPU fans wasn't working. Argh! Next, I tried to check the BIOS if there were things that changed & maybe it didn't see one of my hard drives.  Well, no problems here. I ended up watching the Truman Show on HBO and just kept experimenting with the BIOS configuration.  After a while, I got tired of messing with the BIOS and just watched the movie.  For some reason, the computer was able to boot up right. I did some research and read something about an electrical surge being the cause of the problem and clearing the CMOS settings will do the trick.  Well, I don't think I reset all the settings but somehow it just worked. I still don't know the cause & the fix, but at least my computer is back on-line with all my data still intact...and with much less dust inside.
