I've had an XPS 420 for about a month. About a week into owning it the monitor started going blank at random times. It's still on it just doesn't seem to be getting a signal from the computer. One second it will be fine then it just cuts out and I have to turn the computer off and on again. It sometimes will go a couple of days without doing it sometimes it will do it several times a day. At first after searching around I thought it might be a problem Vista was having with sleep mode so I stopped putting it to sleep and would just turn it all the way off. That seemed to work for almost a week but it's started again.
The PC has
Intel Core2 processorQ6600 (2.40Ghz,1066FSB)
512MB NVIDIA GeForce 8800 GT
4GB DDR2 SDRAM at 667MHz
the monitor is a Dell UltraSharp 2407FP 2407FPW-HC.
Any suggestions would be appreciated
I have this problem OUT OF THE BOX. Wasted over an hour with tech support that had no solutions. I have to imagine it is a driver issue. Not sure wether to blame Vista or ATI or if it a team effort. Anyone figure this out? Mine only cuts out during some power saves and some log outs, not all the time or randomly so I guess I'm one of the lucky. I find if you pull the power cable and plug back in PnP re-recognizes it, same with the DVI cable. I have to admit that I was warned that Vista has had a histroy of driver issues but I didn't think I should buy a new system with XP if they didn't support it anymore. If this turns out to be the next Windows ME I'm going to be bitter.
P.S...Thanks to the sales person I talked to a week before I made the leap who told me how great Vista is :|

Thank you for your reply!
Passed the self test. I'm not a tech but I would gamble that it's a driver issue considering the rep Vista has with drivers along with the symptoms i'm experiencing. Tech support logged onto my system and checked my drivers and said they were "correct". I was even able to replicate the problem with the tech logged onto my system. He said his screen was up and mine wasn't whihc tells me the system doesn't hang. There is a chance it is a bad video card but I would say that is a small one. Are you telling me this is not a know issue? The issue is not random in occurance like it just happens. It is random on the amoutn of log offs/power saves it takes. I did spend close to 90 minutes with tech support so I have tried that. Something about when the computer goes out for a second into power save as it goes back to log ins. I have spent HOURS setting this thing up and I'm not looking to return it. It works fast and I'm not unhappy with the system over all. This is an annoying problem when I log out that I have found a way to work around. The annoying comes from the fact it is NEW.
I've had my XPS 420 for two months now and am having the same exact problem. The monitor goes completely black at random times. This happens once or twice a week.
I have taken the steps advised by ChrisM and my monitor passes the test. I have also tried updating the driver for my video card to no avail.I would love to hear an easy solution instead of having to send back my new XPS.
Here are the stats:Dell XPS 420Windows Vista Home Premium 32 bitIntel Core 2 Quad CPU 2.39GHzGeForce 8800 GT
So what should I do? Is it Vista? The drivers? My video card? I'm obviously not the only person with this problem.

Happened yet AGAIN. This time was unusual though.
I was hovering over a link in IE and the screen went black EXCEPT for the mouse cursor! I was able to move it around the black screen and it would change to a hand icon when it was presumably over a link on the website. The cursor vanished and did not come back when I moved it to the top of the screen.
I am really trying to narrow down what the problem could be and I will continue posting my experiences with this problem.
Fukuisan, you are the main man!!! For weeks now I have driven nuts by this problem. ...searching the internet, etc. I don't know why I didn't think to check the Dell forums and find you, before now. My problem has been with my second monitor going black at odd times and finally, it just wouldn't come up, except for that few seconds just after pressing the start button. It would show the Dell logo, etc., but that's it. I tried your adjustment (but since it is my second monitor, I chose 2700 min and 3500 max. The second monitor came right up and looks solid so far. I'll let you know if this is just false hope.
I had begun to think this problem might be why Dell doesn't seem to support Windows 7 on my XPS 710 with Quad core 2.4 ghz processor and 3GB (really 4GB) of memory, but apparently not.
BTW: I have found almost no problems with Windows 7 on my PC. In fact I find it far more stable than Vista and much faster than XP. The only irritation is that some programs (Nero and some others) that use API's in Windows Explorer will freeze sometimes when I try to access files using the program. If you have any suggestions on this you'll go to the top of my favorite list.
Thanks a million for your help!!!
Well, I wrote too soon. All of a sudden, for no understandable reason, my second monitor just went black. I did notice that my main monitor did go black for about a half second at the same time, but it came right back. Drat!!! All of the elation is out the window.
Hope rises again. My second monitor has been up for 6 1/2 hours now. Even though I am sure my black screen problem started when I updated the driver for my GeForce 7900 GS a few weeks ago, I went back to NVidia's web site and checked for a new driver. Shock and surprise!!! I found one released in the middle of April, 2010. I installed it and it looks like my black screen problem is gone. I will let you know if it is false hope again, but I am pretty optimistic right now.
I am also having this issue with my xps 420.
Dell monitor seems to go dark for a few seconds then comes back. System does not freeze.
When it goes dark, the monitor is not going into standby, power light is still green.
I have replaced the graphics card and same issue.
I switched monitors with another, and same issue.
Only recent change other than new graphics card is new HD and OS, but not sure if issue was before or after.
Read up on how to test the Power Supply using a multimeter and the pin voltages is what it should.
It is pointing more towards a software issue, but i dont know.
Any help please!!
