Alright so here is my problem. When my computer has been sitting a while it won't boot up properly. I will push the power button and the all the fans start up for one second then it all stops. If I keep pushing the power button like 50 times it eventually starts up and boots fine. If I leave the computer running it will run fine for weeks no crashes no nothing it works perfectly. If I turn the computer off and let it sit for 20 minutes and restart it boots perfectly. It's only when it has been off over night or during the work day. If I put the computer on sleep and leave it for hours it shuts off. I thought it was the PSU but I changed that and it didn't fix it. Tried reseating everything and it didn't fix it. So then removed the video card and it didn't fix it. Last thing I did was removing the ram. I removed the 1st stick of ram and all of a sudden it booted up perfectly so I thought bad stick of ram. Put that stick of ram back in and boom problem back. What is throwing me off here is that for the heck of it I pulled out a different stick of ram in the second slot and it seemed to fix the problem and when I put it back in the problem was back. Moved on to the 3rd stick and the same thing. So to me it's not a bad stick it's got to be something else. Now I am a noob so I was wondering if anyone can help me figure out exactly what the problem is. Thanks in advance.
