I'm about at the end of my rope here. Almost four months ago, my PC stopped working. (No post, no boot screen, the only thing that worked was the fans.) I tried swapping out RAM sticks (and then removing them altogether) to see if they might be the problem, but this produced no new results. I also tried removing the CPU to see if I could at least get a post, to no avail.
I figured the motherboard (Gigabyte GA-G31M-S2L) was likely the culprit. It was still under warranty, so I RMA'd it. A few weeks later I got the board back. Got everything all hooked up again and... same exact result as before. I had assumed that the power supply was okay, since everything was still receiving power, but for the heck of it, I took out the CPU/mobo/RAM and replaced it with an older CPU/mobo/RAM that I fortunately hadn't gotten around to selling on eBay yet.
The machine booted just fine with this combination, so I figured the power supply was not the problem. E-mailed Gigabyte to see what they had done for the mobo, and they said that the board had been just fine and that the problem must be the CPU. (I thought this was a bit odd, as I'd have thought the board would at least post for a faulty (or absent) CPU.) But I figured they know more about their motherboards than I do, so I ordered a new CPU (Dual-Core Pentium E5200, same exact CPU as the one that previously worked), and got it a week or so later.
Same exact results with the new CPU. I was getting a bit annoyed at this point, as it appeared that the motherboard was still the fly in the ointment. E-mailed them again and they said I should RMA it again, so I did. The board came back a couple weeks later and lo and behold... same results.
I was very tired of not receiving so much as a hint of the true problem, so I ordered another mobo (MSI G41M-FD), praying this one would at least post to let me know what's wrong. It arrived a few days ago. Got everything assembled (used the newer, unused CPU) and tada! Same results. This time I actually smelled a comforting, burnt odor when I powered on the machine. (I suppose it may have been that some dust gathered in the power supply, so this may or may not be an issue, but it still definitely makes me feel like I'm making absolutely no progress.)
I'll admit I'm not a professional computer technician, but I've built several other systems for friends and family and all have worked fine. Yet I find myself knee-deep in useless components, tempted to buy a Dell (if I had more money to burn anyway).
What in blazes is wrong with this thing?
