Desktop PC – I only have one LCD screen and it goes into standby (blank – off), no mouse or keyboard works to wake it up. If I try to go into safe mode, I get a message “you cannot complete the Window 7 install in safe mode….reboot (OK)”. I installed it on a laptop ok though.

[...] Blank screen after installing [...]

I can’t get the screen up even in safe mode. I get a black or blue screen with mouse working and keyboard. and bottom right hand corner i get text that says “evaluation version Windows 7″ or something like that. any idea what can be the issue. when i press control alt del. i get the task manager and from the run option i can get IE8 or Firefox to work with good resolution.
Any help appreciated.

Have similar or same issue, my Fujitsu Siemens P20-2 LCD is blank but HDMI HDTV goes OK, i have solved this serval times, waiting some time (meanwhile working on HDTV, cca 30mins), then change from duplicated on to extended in basic win7 screen resolution panel. and than LCD starts up. but its not always working in first time. got catalyst 9.6 and HD4870X2 and win7rc1

I found out that some video cards are having problems working with Windows 7 Beta and RC1. To fix this you need to remove the dedicated graphics card and use the integrated one but if oyu don’t have a integrated one you should not have this problem but if you are having it even if you don’t have an IGP (integrated graphics processor) well that’s microsoft…

I have the same problem as this. Nothing I have tried works. I give up unless someone can help me. I have an Acer 5920G with 256 mb ati radeon hd3470 card, 4 gig ram, windows vista 32bit, i am dual booting.

Same problem as above (John & Steve), though I did manage to get it to install and boot a few times on the first install before the problem manifested itself. Subsequent attempts at install have the same no video signal after Windows 7 logo boot (and thereby not being able to get into safe mode to try this solution). Only one monitor, tried both of the dual outputs.

Hey, I was having a “blank screen after install” issue too. Unnplugged all my USB devices and the HDMI cable going to my TV. Booted up perfectly fine now and finished install.

I have been trying to install Windows 7 for a month now. We have used beta RC1 and a full copy, clean install and upgrade all have the same problem.
I have an Radeon 4650 Graphics card BRAND NEW. If it is in the mother board i get to the last part of the set up and nothing just a black screen. The mouse shows up on the background but that’s it.
If I pull the card out and plug the monitor into the MoBo video and it works perfect. I downloaded the drivers put card back in booted into safe mode nothing. Take the card out install the drivers put card back in nothing.

Please help

i experienced the same black screen issue after attempting to install win7 ultimate. seems it doesn’t like having two monitors plugged intot he graphics card. I had to unplug the monitor that was using the dvi side of the card. after that the log on screen appeared.

after i finished the installation, there is no issues with having both screens plugged in

Same issue, 1 monitor and 2 digital outputs and Nvidia 8800 GTS card, with a 64 Bit Athlon 64FX CPU.

Any solutions?

I have a similar issue. my acer 7535 went blank after installation. F8 does not work. neither does any other key. Need help.

I had the same problem. I was usind an ansus tower with an ansus P5B SE mother board and 4 gigs of ram. I am also using an Envidia 9800 gtx grafics card installed windows 7 32 just fine but when switched to 64 had all the same problens as everyone above. I disconected everything attached to the USB and then pluged the monitor, keyboard and mouse back on I got like a wisk of it trying to work but to no avail. Any help would be greatly appreciated.

i also experienced black screen after upgraded my dell computer from vista business to window 7 pro.

The problem is like this:
1. turn on your computer >>>
2. DIOS post >>>
3. 4 glowing sparkles fade in and “starting windows” under it. >>>
4. black screen, it does not boot to window log in screen.

try this to solve it:
1. go to your computer manufacturer’s website to update the following drivers for window 7:

2.DIOS driver;
3.Monitor driver;
4.Video driver;

at the time of writing this post, it works for me, i have turned on and off 4 times, there is no black screen.

by the way, when you update DIOS, you have to wait 10 minutes for the system to complete.

Same as John, Steve, G, safe mode comes up and visible, but it doesnt let me do anything in safemode as the installation has not finished, and it forces a restart.

I am a developer myself, and I think its shambles, what are you up to at MS, why dont you build stuff modular and logically (if u did, why would safe mode display something). Geee
