Okay so as the title states my computer's hd 4600 drivers only work in safe mode. What makes it worse is the last time I used the computer I was just fine. I used my computer on Friday, played some games etc and turned it off at night. I did not touch the computer at all on Saturday, it was not turned on. Sunday I tried to turn it on, which it did, and it stops sending display signal when windows is about to ask me to log in. Before then and in safe mode it works fine. When I delete the intel drivers while safe mode, and reboot in normal mode it displays the signal.

If I did not touch my computer what could have changed, and why does it seem the version of drivers makes no difference. I have not updated the drivers and it was working when I used it last.

Additionally I tried reinstalling windows since it seems to be a windows compatibility issue, but the installer didn't wipe my old files like it said it did. Not only that but it won't load my ethernet drivers, but it loads my pci wireless drivers.

I have reinstalled windows 7 and it i am having the same issues. What is going on? Is in Intel Hd 4600 a trial or something( Obvious joke)? Ugh. I just want my computer. Halp much appreciated.

Is it possible that Windows Update is updating the driver to their latest WHQL driver and when you reboot, then it's messed up. Try shutting off Windows Update (or at least make it ask you before installing updates) and then install the newest driver from Intel.

I have tried this multiple times. I installed the latest driver from Intel's website from my laptop then put it on my desktop through usb. Now what's happening is the drivers are installed, but Windows is saying they aren't working even after multiple restarts. Sm bus drivers always not working.

What motherboard do you have?

Sounds like you may have some other drivers missing. I would try downloading and installing the chipset drivers, reboot, then install the iGPU drivers.

Okay so it seemed the installed driver version didn't match what I had downloaded it. Also I uninstalled it and tried to reinstall and it tells me that I don't meet the minimum requirements this time.

Alright well I installed everything and it brought me back to my original problem. I wanna give up but the fact that i didn't do anything to my computer and it's doing this really really annoys me. I'm out of ideas.

Have you tried a System Restore to a point before it started acting up?

Yes. It didn't work. Since then I wiped my hard drive reinstalled windows came across the problems i just explained such as certain drivers not being available. I installed more intel stuff got them working rebooted, and when windows is about to ask for my log in, no signal. The same problem that I had when I had all my stuff on my hard drive. So I would say it's not on my end. Also my motherboard is not giving any unusual codes. It did for a bit, i hit the cmos button and resolved it.

I wonder if the iGPU is putting out a refresh rate not supported by your monitor. Do you have another monitor you can try?

Yes I do, I will try that. Can you think of a reason it would suddenly change after it's been working for months? This problem has to be the most random thing ever.

I plugged in a vga cable to my other monitor and it displayed. Testing dvi now. Must be a hdmi problem only in normal windows that decided to occur while off for a whole day?

The dvi port works as well. That means the hdmi is the problem. But since it works in bios, safe mode, and before windows fully boots the port itself is working.

I would say that the DDC info isn't being reliably passed to the graphics card over HDMI. It shouldn't matter, but try another HDMI cable if you have it.

I did that and it either worked meaning the cable wasn't working with my computer, or it actually just decided to work. The original cable I was using works in my PS3 so who knows. But I guess problem solved. Thanks for your help.
