I attached the monitor via dvi cable and I'm using the integrated graphic card (Intel HD2500)
My problem: yesterday, when I turn on the pc, after booting (after windows 7 logo ) I got the message ''enter power save mode" on my screen and then it entered in sleepmode because there isn't signal ...my pc is new (I've got it from 5 days) ...also my monitor is new
If I attach the vga (analogic) cable, there is signal and the pc works fine ...there is signal also with dvi cable in safe mode (F8)
I tried to boot another pc (with windows XP) to my screen with the DVI cable and it worked perfectly ...so I do not think it's a problem of DVI cable or a problem of the monitor
But If I attach a dedicated video card (I have a Radeon HD 5450) and if I leave the DVI cable attached to dvi output of the integrated video card (Intel HD2500) now there is signal after booting, but there is no signal during booting (till windows logo) ...the opposite!!
What is the problem? I think it's a HD2500 problem
ps I installed the latest drivers of Intel HD2500 (version 188.8.131.5296)
pps if I use DVI cable with a dedicated video card (HD 5450) there aren't problems, so I think I'll use this card (or another dedicated vga) becauseI spent48 hoursin front of thePC in vai and I think it's a Intel graphic problem ...what do you think? I want to understand what's the problem, if the problem is from the integrated video card HD2500 ...and if this problem can cause others problems
Thank you in advance for your replies and I hope I can clarify this!
You are saying that your computer works with VGA attached and safe mode as well. In that case, there is no problem with the graphics controller. I recommend downloading a new version of the graphics driver this is version 184.108.40.20661
