I've been helping a friend with a custom built computer.  It has a I7 Quad Core Processor and 8 gigs of Ram.  Runs Windows 7 Home Premium.


When I first started working with the computer the video connection signal would not work.  After looking online I found that removing, cleaning, and reseating the Ram might help in getting the video to work.  I did that and it did in fact work and the video worked fine. 


I spent 2 days cleaning the computer and making sure virus protection was in place.  All worked perfectly with no further video feed problem.  Then last evening I turned on the computer to show my friend how well the computer was working and I had the same problem with the monitor going to sleep.  You can hear that the computer is logging on to Windows.


Is there anything else I can try to do.  Would it make any sense to remove the video card, clean it, and reseat It like I did the Ram?


Thanks for any and all suggestions.

Hi JazzMahn,


        what is the motherboard, video card and  power supply make/model/specs?


               if possible, a speccy link would be helpful.


Publish a Snapshot using Speccy - http://www.bleepingcomputer.com/forums/topic323892.html/page__p__1797792#entry1797792 , taking care to post the link of the snapshot in your next post.



              Upon the initial boot, are you seeing the splash screen? usually it is an OEM such as Dell or HP. but for custom builds, it is the motherboard model, accompanied by the boot options like F2 for safe mode or BIOS etc. if you are getting the initial splash screen, then there is hope!!!
