same problem with my new pc, no signal after booting, I use a HD2500 Intel graphic card, see my topic no signal before or after booting
very annoying issue! I think I'll buy a dedicated video card...
Why is intel taking so long to respond? Don't force me to buy a separate graphics card, and make me regret buying intel,
In my case, screen goes black but comes on after several seconds. This happens several times and completely goes away after an hour or so. Tried oem & intel drivers, windows update. Test with dvi and vga cables. No luck.

Tried Intel latest beta driver and got my dual monitors working. These are for Win 8, but seem to be working with Win7 also.

After about 2 hours of running time, I lost the second monitor again. After re-installing drivers, everything is working. Second monitor reappears in the middle of installation progress (I think it's after creating new registry entries).
Now this is really weird. Probably hard to believe. But here goes.
I have my PC, monitors, two external hdd-s and a desk lamp all plugged into the same electrical socket. APC Surgearrest goes into the socket and everything else is connected into Surgearrest. When I switch my desk lamp off, second monitor goes black.
I can post a video, if you have hard time believing it. Just tested it three times in a row. Reinstalled the drivers, second monitor starts working, switched the lamp off and second monitor goes black. Switched the lamp back on, reinstalled, and monitor starts working. Switched lamp off, monitor goes black.
PSU is Seasonic X750, monitors are Samsung SyncMaster 2343BW, desk lamp is some noname 10y old model.
I think the power adapter on my desk lamp is failing. It was almost too hot to touch.
I'll try to do some measurements to see if it's emitting any harmonics, RF noise etc. But to be frank, I have no idea why switching the lamp off results in loosing the second monitor.
Just bought an i5-3570K with a Gigabyte Z77-D3H motherboard and I am also having this problem. I have downloaded and tried the latest drivers from the website today, but this has not fixed the issue. I have tried the fix that phil_l has posted but it has not worked. The whole point in buying the i5-3570K was so I would not have to purchase a GFX card. This is a serious issue that needs addressing asap.
Any chance of an update Intel?
Having the same problem as so many above -- Intel driver means black screen after Windows boots. Bios shows ok; safe mode is ok; normal Windows ok only after I use safe mode revert to standard vga driver. Everything else seems ok.
This happened with a couple versions of the driver.
The monitor-unplug trick didn't help.
Then, after lots of updates, I switched to a vga cable and the picture came back. Then it stayed back after I went back to HDMI !
Core i5 3570k, asus P8Z77-M, single monitor with HDMI cable. Brand-new build, no fancy utilities or even applications yet; no hardware beside mobo; HD, CPU & cooler, Seasonic ss-560-km psu & a blue-ray player. Bios updated yesterday.
