Intelligence needed to truly protect kids ('computer)
Sorry for the topic title. But if you are the kind of person who is willing to save the children, you are the kind of person to care that my kids' first experience of building a computer should be saved. As it has just hit a brick wall. We are rebuilding one of my old computers (for my kids) but something has gone wrong. It was working fine a couple of days ago but since I removed the motherboard from its case and reseated it in the new case, it just turns on for 20s and then cycles the power - no display, no post. Here's what I have tried already: - Removing/replacing all connections including all SATA, system fan and case connections, just connected 24pin mb power, 8 pin cpu power and cpu fan right now, - Removing motherboard from case entirely, ensuring no short circuits. Open test bench right now. - Clear CMOS (both through jumper and removing battery) - Replacing PSU with known good PSU - Replacing thermal compound on CPU cooler - Removing GPU entirely so it is not a factor (PC was working fine using MB VGA output a couple of days ago) - Removing RAM sticks and only using one at a time (tested with three different DDR3 sticks, same result all three times) System specs: MSI z68a-gd55 motherboard, 8gb DDR3 RAM, i5-2500k, CM Hyper evo 212. Everything else removed. Obviously, it's an old board and old CPU, but if anyone has any ideas before I finish tearing my hair out, I would be very grateful.
You might have adjusted a pin inside the socket. That’s why I prefer the older socket designs where pins are on the CPU rather than in the board. Sometimes these pins can shift slightly, leading to issues like yours. On your Z77 OCF board, I usually just reposition it and reinsert the CPU. In your situation, does the board display a POST code? If it’s showing and getting stuck at code 55, that’s likely the cause. Check the socket carefully for any pins that may have moved, and consider using a magnifying glass or light source if needed.
Many thanks for your help everyone. @Beerzerker I have now tried reseating the cpu again. That was a really interesting comment - it does look like one of the pins on the LGA is not straight. I've tried gently pushing it back in line but I haven't had any success. I'll keep trying though. Here's a pic: Does that look bent to you? Close up:
It seems someone was nudged off their seat, which is enough to cause them to react. Realigning it with the group should resolve the issue. Be patient; these parts are delicate but manageable.
