Is my motherboard going bad?
My computer is 8 years old, but does what I need it to do. My hardware is a Gigabyte EP45-ID#P mb, Intel core 2 duo 8400, Corsair TX 650 power supply, and because I thought it was my graphics card, a new MSI Geforce 950. Memory is G Skill DDR2 1088 which test as good. When I power on my computer, I see the posting screen, and sometimes, get to the welcome to windows screen before the monitor goes blank for around 3 minutes. Then the monitor pops on, and off, a few times, then works perfectly. The monitor works if I use it for streaming TV, I tried a new cable to the monitor, I had the same problem with the old, and new graphics card. A software program tells me the voltages to the mb are good, and all the temps are excellent. I have a power supply tester on order. To rule out viruses, or software problems, I installed a new hard drive and did a clean install of Win 7. I know it is time for a new build, and I am saving up for that, but I would really like to identify the problem I have.
