Strange Problem,need help!

[HardLiner]

I started up my computer and did a virus scan with AVG(as I usual do) and it said there was a partition change(MBR)in the test result.... I thought that was strange but thought it may have been a corrupt file or something and didn't think any more of it. Then about an hour later I went to play BF2 and when I clicked the BF2 desktop icon to start the game it said please put disc into cdrom so I opened up my cdrom and noticed the disc was already in it.I then went to my computer and it had no cdrom drive detected,so I rebooted my computer and when it went to restart it got stuck on the bios logo screen, I then turned off my computer for a minute or two and turned it back on and now everything is working normal again and my cdrom is now detected? also I don't get a partition change(MBR) in AVG anymore.

Could it be a virus? could my motherboard be craping out on me(it is a new computer 2 months old) one other thing is I left my window open where my computer sits by and it rained out last night...I didn't notice and wetness on it but could any moisture have caused the error??



Sorry If I'm posting htis in the wrong place becasue I'm not sure what the problem is ..software or hardware?

Could be a loose cable causing the optical drive to disappear which caused a secondary HDD to change drive letters. That's a wild guess though.

I checked the cable and it seems tight.I'm hoping it's a windows glitch and won't happen again.
