Hi! Recently I have been having a problem that when I
first start surfing the web after having my computer off
for several hours, the whole thing crashes. Monitor goes
black, then several vertical colored lines come up. My
entire computer has no lights on, and is non-responsive.
I have to reboot (physically turn the power button off).
Any ideas?

Sounds like hardware malfunction,with the lines video adapter,or
if you use on board video,motherboard failure.If its older board,
replace it.

If your computer was "off" do you mean 'standby' or 'hibernate?' Then, I'd
check the graphics and the power saving features; i.e. the graphics chip or
RAM overheats while the cooling fans are running to slow due to power saving
or 'quiet system' features; when you reboot, the fans work in full thrust
mode thus cooling the video chip.

Otherwise, check your graphics with some utility - you find many on the web.
Also, the voltage might be fluctuating, faulty graphics drivers, no page
file and so on.
