So, I had to RMA my motherboard that I had for about 9 months, because the USB ports mysteriously and abruptly stopped working. I just got the replacement board delivered to me a few days ago, so of course I immediately put my computer back together. While I was waiting on the board to be given back to me, I invested in some antic-static gear so I could be sure that I would be able to safely put my computer back together, so I know static wasn't an issue in this case. So anyway, back to the issue: I put my motherboard in the case, then the CPU, along with some Arctic Silver 5 thermal paste, then I put the heat-sink on. Next came the RAM, then the GPU, then all the power connecters, front panel cables, etc. As soon as I was sure that everything was hooked in correctly, I powered my computer on only to be disappointed when I heard 5 beeps that I know wasn't a successful POST-test. I have tried everything I have read on other forums so far, like making sure the CPU was seated in correctly, making sure the RAM was in good, using only one stick of RAM to power up with, taking about the CMOS battery for about 5 minutes and then replacing it. Just a few minutes ago, I even tried taking out the motherboard and placing it on the box it came in to see if the case was the problem, but my motherboard won't power up when it's lying flat — only when it's inside the case and the case is upright.
Another small detail is when I was checking on my RMA by emailing the company, the person who responded said that the technician tested the replacement and everything passed, and the BIOS version was updated to the newest version. What I think is that the newest version may not be compatible with my CPU or something, because before I got this replacement, everything worked beautifully.
Any tips I haven't tried or advice is greatly appreciated in advance. I'm at my wits end here. XD I don't want to have to RMA this thing again, or buy a new processor.
