So. There I was, yesterday, playing happily, when suddenly and without any warnings, my computer rebooted. "Egads", thought I. Might my CPU be overheating? Went into safe mode, checked, my CPU was around 32 degrees Celsius. Everything fine. "Ah well", I sighed, and rebooted the computer to run in normal mode. After five minutes, it shut off again. Crap. Checked a few fora online, disabled ACPI and came up with the conclusion it's probably due to a failing PSU, prompting the computer to reboot when it doesn't deliver enough power to the MOBO, as there are no hardware beeps, BSOD's or anything indicating a software problem or a hardware problem due to a malfunctioning video card. Tried to start the computer a few times, once it worked allright until it rebooted after I started a game that requires a lot of... resources? RAM, CPU etc. Crash. And now, the computer wouldn't even start up BIOS. It reboots three seconds after hitting the power switch, and there isn't a single thing on screen while I turn it on. "Ah well", I thought again, and proceeded to remove the 400W PSU in order to try it out with a friends' more powerful one. And then... the horror. My 20-pin ATX connector had one fried pin. It looks something melted, it's caramel-colored. So, the computer now reboots after a few seconds, not even going into BIOS. I'm afraid the melting pin damaged my Mobo, permanently. And I hope it's the only thing that broke. So, any ideas? Maybe my forensics examination is utterly wrong? Can one repair the pin-connector on a motherboard? Ye guys think I'll be able to get a replacement via warranty? SuA, Halp!
