Off topic a bit here perhaps but we have a Compaq Presario CQ56 and a CQ57 also. I can't remember what one I was using at the time but all of a sudden this screen started doing cart wheels , I hit "esc" key and the screen stopped in a sideways position.
I took this picture but I wish I had the fore thought to film it spinning before putting the kibosh on that odd computer behavior.
I want a new computer for photos and film production and I think that I'm in for some sticker shock. The computer that I want to buy would not be connected to the Internet if I can help it.
I would using it with several different types of printers and want it to remain a "virgin", The Internet is so dirty with bugs.
Both have windows 7, they are 64 bit systems and seem to be a bit problem prone.
It is usually not that hard to do a restore, for Pete's sake we've had to do it a bunch of times with these computers.
Sometimes we feel that our computers are our daughters and they just hooked up with unsavory "dirty" boyfriends that they met on the Internet.
One of the computers seems to not want to install an update that keeps trying to install.
Sorry I can't help the OP or anyone else with advise but good virus protection seems to keep being outsmarted by folks continually and it seems to be a pain in the patootie for all and very costly for some. Sorry if I high-jacked this thread.
Anyway this is the photo that I did manage to get of our computer when it was wigging out.
