HD4000 Screen flicker after cold boot

[EHoll]

Greetings everyone!

My system configuration is as follows:

core i5-3570k, using hd400 igp

intel dh77kc motherboard

kingston 4GB DDR3 RAM Module (1 stick)

Win7 32 bit

Graphic Driver: Intel Version 8.15.10.2639

Monitor: LG, Resolution 1900x1200, DVI Cable

A few days ago I switched to the new motherboard above and refreshed the whole software installation.

From now on, when the system is booted from cold, there is a reproducible screen flickering for the first 5 Minutes after boot.

The screen flickers every 2-5 seconds and gets black for a second.

My previous board (Gigabyte z77ds3h) didn't have that issue.

Rebooting a "warm" system does not show that issue.

I've read in another thread here, that a similar problem was solved by switching to another driver version. As far as I know, I'm already using the newest driver.

Can anybody help?

Hi Kevin,

Screen is still flickering on boot.

Hi mrAtari,

I am sorry to hear you are still having problems. Please try clearing the CMOS in the board by disconnecting all components from the board and remove the battery for about 20-30 minutes.

Besides this, I recommend you updating the bios in your system. Here is the download link:

Here are some other steps you can try:

1. Test a different power supply if possible.
2. In the case you are using any video adapter/convertor try using direct connection.
3. Test another cable if possible or a different connection.
