Close Opera and Computer retarts??

[rspassey]

What is this...?

I was working on my computer in my sig, had opera open and was browing pcmech, then I got hungry, and exit out of opera. At the same time I exit out my monitor flashes "no signal" and my computer restarts. I checked error log.. and nothing.. then I tried it again and guess what, it happened again. Once again nothing in error log
This is killing me that I cannot pin point it. I did a google search and it yeilded nothing, tried searching on Opera and nothing. Suspected a virus so ran Avast home; all my spyware removers, and will try again when the scan end. I wish I knew what was going on. So far nothing has showed up spyware related. And I made no system configuration changes and did not change anything within opera itself.

Anyone got any clue or experienced this before?

TIA,
Ryan

I finished scanning; but nothing was found... I also tried a re-install but that did not help anything. What do you think I should try next?
EDIT: Note that when trying to close through task manager the same thing happens.

Look in your event log and see if there is any hint there.

I think I mentioned I tried that, and it shows nothing. I have uninstalled everything about it; and we back to using FF for now. Perhaps later I can try again. Thanks though.
