Monitor Loses signal on boot up

I have a Viewsonic LCD monitor. i just put a new pc together with an XFXForce
8600GT video card. The problem is when i boot the pc i see the bios screen
fine. it's not until i see 'Micrsoft Corporation' and am about to see the
status bar going back and forth that the screen goes blank and i then see 'No
sginal'. I'm connected using a DVI-I cable. If i unplug the cable from either
the card or monitor and plug it back in i then get video. I sent the monitor
to Viewsonic which they said they fixed a problem. hmmm anyway i'm still
seeing this proble. If i use a VGA cable with a DVI adapter i won't have this
problem. While the LCD monitor was away i used an old CRT monitor with a VGA
cable and had no problem.

Any suggestions or ideas would be appreciated. This is driving me nuts.

I have the same monitor and tried every fix available....non worked.
The problem is in ViewSonic's defective internal power supply unit.

The only solution is to purchase a new monitor.

This is what I purchased and it is fantastic:

DId you try having them repair the power supply? how do you know the power
supply is the problem? i'm not about to buy another monitor without first
trying everything to fix it or sell it which will be hard. Samsung's are nice
monitors. i have an old crt and it still works.

This is what I did to try and resolve the same problem with my ViewSonic monitor:

- Installed a different video card
- Installed a different DVI cable
- Installed a new computer power supply unit
- Installed a different monitor power supply cable
- Tried monitor with two other computers running Windows XP

None of the above worked. Bought new monitor and problem went away.

It wasn't until i went to a DVI cable that i saw this problem. the new video
card only has dvi jacks so when i used this monitor on my old pc using a vga
cable it worked fine. i tried different cables also with no luck. the reason
i'm trying to nail down the source of the problem is because trying differnt
things gets expensive. i do appreciate your help. i had the same thoughts
about this monitor also. i want to be able to go back to them with something
definitive.

thanks again

Had same issue running, ACER with dual DVI on XFXForce GTS 8600.

Made sure my Monitor settings where set for Digital and not analog. Then
booted to safe mode and installed drivers. Has worked fine ever since.

It did come with a dvi to vga adapter which works fine when attached. i tried
using it on the dvi cable to attach to the vga port on the monitior and on a
vga cable attaching to the dvi port on the card. both work fine. it's dvi to
dvi that doesn't work. this is something else isn't it?

really! i downloaded drivers from viewsonic with no luck. i may try that. why
did you boot in safe mode? just curious. my monitor is set for digital i
think it's a piece of @#$#$# like the others are indicating

Make sure you don't have both the VGA and the DVI cable connected to your
monitor especially if your monitor does not have the ability to select
between the two input connections.
If you perform a F8 safe mode boot do you see the BIOS screen and not the
windows screens when you are using a DVI to DVI cable?

i will get back to you on that. i don't want you to think i'm not answering
you. i'm only using the dvi cable. i tested this a few ways. I was talking to
my wife about this and she reminded me that we had broght this pc up to a
shop and they connected a lcd monitor to the pc and it came up fine. that's
when i got suspicious of the monitor. when the pc first comes up i see the
bios screen then it loses connection between that point and the microsoft
scorporation logo and the sliding scale bar. once i unplug the cable and plug
it in it's ok.

Apparently you are not sending the monitor a resolution that it will accept
over its DVI interface.
Boot up in F8 Safe mode and Windows should run in safe mode. While in safe
mode change the resolution that you are sending out over the DVI connection
to the native resolution of the monitor. The next time you boot in normal
mode the monitor should be working.

ron

ok i'll try that. at the risk of sounding stupid how do i know what the
native resolution of the monitor is. i don't have a manual for it. why can't
i just adjust the resolution in my computer?

Get the model number off the back and look it up on the manufacturer's
website.

1024 X 768 which is the max i can go. i got a manual online and the manual
says the max resolution for the monitor is 1680 X 1054. i have it at 60hz. i
can't seem to get the resolution rate of 1680 X 1054 anywhere. i'm going to
ask xfx if there's any updates i can get. i did try to update the driver for
the card and i lost the signal again

I spent several weeks trying every type of troubleshooting technique
I could find to save my ViewSonic monitor. It was working perfectly
for over a year before the problem developed. I'm convinced the problem
lies with the integrated power supply within the monitor itself.
