Hello everyone,

My monitor screen goes blank (white) all of the sudden for no reason! At first, it was just all white, but lately, it has vertical dark thin lines against a white background.

Details:
I am usually clicking something (browsing the web, opening a program, etc) and the monitor goes blank. The monitor light stays green. The HD light doesn't flicker. The monitor doesn't flicker. I've tried all combinations of keyboard keys including Stand By, the Windows key, ALT-CTRL-DEL, etc, but it does nothing. I've tried inserting a CD with some program setup in it, nothing. I have to do a cold boot to get back to what I was doing . Needless to say, I lose all the work I was in the middle of ... *sigh*

I am at a loss! I bought this computer in July/August 2005 but I kept my old monitor. It happens maybe 2-7 times a week. Please help!

Here are the specs:

HP Pavilion a1130n
AMD Athlon 3500+ / 64 processor
1GB SDRAM PC3200 DDR
250GB HD
ATI RADEON Xpress 200 Series / 128MB

Monitor:
I think I bought the monitor back in 2001 or 2002.
Viewsonic PF790
19 in CRT
Screen res: 1280 x 1024 @ 85 Herz
I have installed the latest driver from the Viewsonic website

Thanks in advance,

Jessica
