I have a 4-year-old Mesh computer which over the past 24 hours has
developed a problem with the screen display. It will display OK for a
while then will act as if Windows XP had turned off the monitor. I will
get messages such as D-SUB, DVI-A and DVI-D. The Windows screen will
flicker on and of intermittently and after about 30 seconds of this will
display properly.
I've run Avast! antivirus which gives a clean bill of health, SpyBot
which gave an XPantivirus entry in the registry which has been removed
as have 3 tracking cookies. Superantispyware removed another 9 tracking
cookies otherwise the operating system seems healthy.
I've run Video Card Stability Test on the NVidia GeForce FX 5900XT which
gives a benchmark within the normal range for that card, so some of it
is working. I don't know of a way to test my ViewSonic VP181b monitor.
Do these symptoms indicate to anyone whether the monitor, video card or
anything else is failing?
One last piece of information. The problem appears only after the system
has been working for a while and has warmed up.

When it goes off, does the power led show standby mode? If not, try
another power lead.
Does it have a removable signal lead? If it has, try another one. If not,
double check it is plugged in to the graphics card properly.
Finally, remove and then re-seat the video card just in case it's not
sitting in the MB socket fully.
If the above doesn't help, the most likely fault is the monitor; can you
borrow one from a friend to confirm it?
