Windows 7: Dual Monitors going black randomly

Dual Monitors going black randomly

I have a user who ever since we added a second monitor to her setup has had an issue where they will both go black for a second before coming back on. She says this happens about every hour.

Laptop - Lenovo T450s on Thinkpad Ultradock
OS - Windows 7 Enterprise 64-bit
CPU - Intel i7 2.6ghz
Memory - 8gb
Monitors - ViewSonic VG2228WM-led

So far I have replaced the dock and power supply for the dock. Replaced the monitors, video cables (even replaced the 2nd VGA with a DVI-HDMI), and power cables. I have completely removed and reinstalled the video drivers for the laptop with reboots in between removal and reinstall.

Some new information today was that when the screens go black the power light stays blue (turns amber when no signal).

I am not sure if this is a profile issue or if the laptops motherboard is having issues because she never had the issue until the 2nd monitor was installed.

Any thoughts would be appreciated. I am just about to the point of a rebuild.
