Windows 7: Blank screen after startup

Blank screen after startup

I have a problem that seems to be common and I still haven't found the solution after 2 days of searching the web.
I've installed Windows 7 and it works fine only in Safe Mode or if I disable 9800 GT else I get blank screen after startup.
Solutions I've found searching the web:
1. Change graphic card driver - tried from 181 up to 197, no change
2. BIOS update - did it, no change
3. Plug in the monitor into second DVI slot on my graphic card - no change (I don't have an onboard graphic card so I can't test with it.)
4. All kind of tiny little solutions that I've tried with no succes.

I'm still not sure what is actually causing the problem. At first I tought it was the graphic card but after a deeper web search I've stumbled up on something called EDID and monitor not being detected corectly. By the way my friend has the same graphic card and it works fine on his PC.
My monitor is CRT SONY and I'm using VGA to DVI switch to plug it in.

P.S. blank screen doesn't mean It froze or something, I can still hear starting chime and than an error sound like somehing isn't working.

If someone had the same problem and solved it I would really like to know how.

Try updating your system drivers one by one (can you compare them to your friends motherboard driver dates?
Things like an old SMbus driver etc can cause your problem!

Updating bios or motherboard chipset drivers to latest seem to give most solutions ie letting 3d mode lock on and integrate

Download/install latest DirectX package (Feb2010)

There are loads of 9800(GT) threads on here to look thru too!

When you get really fed up with it all, delete your "PCI bus" driver (in "device manager") and let Win 7 download/rediscover all your drivers again.

Then reinstall latest Nvidia downloads
