Hey,
So i have an old system with a C2D E6750 paired with a GTX 1050 that i decided to upgrade to a quad core processor. Since i could find a good deal on a Xeon E5440 i bought it. When i installed it the system turns on, fans spin but i either got no image or it takes forever to boot and the video is like rendered from top to bottom of the monitor and the bios takes two of this cycles to fully load a page, in each page. The thing is: i tested without the graphics card and everything seems fine, tested with a Geforce 8600GT and everything seems fine too. Do you have any suggestions of what it could be?
System Configuration:
Processor: C2D E6750 / Xeon E5440

RAM: 2x2Gb DDR2 800MHz
