Windows 7: no signal before or after booting

10 Jul 2012   #1

Windows 7 Home Premium 64bit
no signal before or after booting

Hi all
I'm new here (I'm italian, excuse me for my bad english) and I just bought a new pc :

Intel quad core i5 3450 3.1 GHz socket 1155 Ivy Bridge
mobo AsRock H77 PRO4/MVP
psu XFX Pro 550W
8gb ram Corsair Vengeance LP
HD WesternDigital Caviar Blue 500gb
Samsung DVD
win 7 64 bit

Monitor: Dell U2412M 24'' 16:10 1920x1200px

I attached the monitor via dvi cable and I'm using the integrated graphic card (Intel HD2500)

My problem: yesterday the power went out (without problems for me, because I've got an UPS) but after this, 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

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 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?
ps I installed the latest drivers of Intel HD2500 (version

pps if I use DVI cable with the dedicated video card (HD 5450) there aren't problems, so I think I'll use this card (or another dedicated vga) ...but I want to understand what's the problem with integrated video card

Thank you in advance for your replies and I hope I can clarify this!

Kind regards
