I'm having a HUGE problem with my HP Probook 4520s and I suspect the motherboard... A little background information, I had thermal problems the day I bought it. So I ripped a hole into the bottom of the laptop, applied all new artic silver 5 and it ran great. Recently it overheated due to cpu fan failure, so I bought a new fan. I replaced it and repeated the above process... First boot up was fine everything normal, better temps everything. Second boot up my screen was grainy and all my black colors come up green. I thought maybe by some small mistake I put a hairline crack in the LCD so I bought a new one and replaced it. Still grainy and green. Checked the LCD cable and bought a new one just incase, replaced it and still grainy and green screen. Now if I plug it into my tv through the HDMI output everything is FINE. Displays properly. I'm wondering has anyone else had this problem? Could it be the port the LCD cable connects to, and if it is can I do anything else before having to buy a new motherboard? Mine is the ATI 6370 Radeon so its a little pricey... I have pictures to help with any questions anyone might have. Its running a corei5 2.67@ 2.93ghz 8 gigs of ram and 500gb hard drive. I have a good hardware knowledge as I have been working on computers and refurbishing them for 7 years. Just looking for some ideas/input from anyone. Thanks in advance for everyones time.
