I recently bought another video card hoping to squeeze a couple more years our of PC gaming but have since had a major system malfunctions. My current situation is that the computer does not seem to post (nothing on the monitor). I checked the video card and also the previous card on another computer and it seems to be ok. I have also tried new RAM which was sitting around in its original package (unused). Nothing. I get no beeps or anything. After a few seconds or a few minutes the computer will power off. I tried a known working PSU and it does the same exact thing.
One thing that I noticed is that the SB green LED on the motherboard is on, however when I disconnect power from the wall to the PSU, that light goes completely out in a matter of 2 seconds. Is this synonymous with system board failure? Or is there perhaps anything left to check?
I have hooked up my digital multimeter to the 20pn ATX power and each connector pin tests within the correct voltage, I even checked the CPU and reapply a light coat of thermal compound. Nothing seems to work.
I am not very experienced with motherboard troubleshooting as I usually by ASUS and have had nothing but luck with them. this one is at least 2 years old, could it just be at the end of its life?
