Reply #11: I thought of virus because

[Why Syzygy]

I had a mchine issue the night before, but finally chalked it up to bad Avira update. Avira has started demanding a restart on updates. I watched several hours of Heroes over the weekend, and when Avira wanted to update, it slowed the video down and glitched. So I ok'd the update, but then the machine was almost unreponsive altogether. So. . I stopped everything to reboot. That resolved the video/browsing issues. Also when the flashing started, I ran a virus and malware scan. It slipped my mind that I intended to run Windows OneCare to rule out any registry faults. I'll do that today. The cables get very little contact with any outside sources. New puppy has been back there a few times. I've removed them from the monitor when I was going to open it. I'll double check the plug into box, it was tight. I went to bed really late/early Sunday, and it seems like there was something unusual on the screen. I was so tired, I looked at it, and decided it was okay. I had suspended screen saver to watch videos. Now I cannot remember what it was :( x( But the display is obviously okay now, xcept for the flashing! And since I had the prior issue with the power button, and it staying on, it does seem reasonable that it's th ebutton. Thanks for all your input.

edit: I just spoke with a repair tech who told me it would be cheaper to replace. (I'm not having nearly the success today with dealing with the flashing as last night.) :blink:
