I have an Inspirn 570 hooked up to a Dell monitor, which stopped displaying the screen, it is just blank. To be more specific when I start up the comuter it shows the startup screen, but when my Windows 7 Home would start loading the screen goes black. The funny thing is that when the desktop is running and I turn off and on the monitor I can see my usual desktop, but only for a second, then the screen goes black again.
I hooked up the monitor to my laptop and it worked fine, so I don't think that the monitor is at fault. I also took my desktop apart (it's way out of warranty by now) and cleaned the inside thoroughly with a vacuum. That didn't help either. My guess (without knowing much about hardware stuff), that the videocard doesn't get enough juice. Am I correct? how do I fix it? or what can be the problem?
I would recommend you to update the Video drivers by clicking on the link given below:
Please ensure that you select the Operating System as installed on your computer to download the latest Video driver.
If there is an external video card installed, would recommend updating the video card drivers from the vendor’s website.
You may also run a test to check the hardware functionality. To do so, please restart the system and tap F12 which will take you to “One Time Boot Menu” Choose diagnostics and let me know if you are getting any message upon the completion of diagnostics:
You can also refer the Dell Article 266787 on our Dell support page.
Please keep me posted with the results.
Thanks & Regards
Thank you, this all sounds good, but without being able to see anything, without a screen I cannot update the driver(s). I cannot work it without seeing what I am doing. I tried to start with the F12, but the screen went dark right before I could select the Diagnostics option. So then I turned off and on the monitor and saw it long enough to select the diagnostics. I ran it and found no problem with the memory. I will keep running it, although it is very annoying to turn off/on the monitor to see the screen for less than a second.
