alyusha Posted September 24, 2016 Posted September 24, 2016 Tested PSU, runs fine. Plugged in only 24 pin Mobo power wire, all lights blink and won't boot. PC was running fine til I shut down and took out GPU to check something. I of course tried testing with no GPU, still blinks. So I am assuming that since no other parts are plugged in, it's safe to assume I fried my Mobo? Sorry for the short topic, in a hurry to get to the store before they close. Thanks.

bp9801 Posted September 25, 2016 Posted September 25, 2016 What motherboard is it? Plugged in more than just the 24-pin power cable? What did you do when shutting it down and removing the GPU? Any shorts somewhere? How old and what model is the PSU? Did you try the PSU in another system? Have another PSU to test in your rig?

SpikeSoprano Posted September 25, 2016 Posted September 25, 2016 Besides the 24 pin mb plug you also have to have the cpu power plug in (either 4 pin or 8 pin), or all you will get is blinking lights. Share this post Link to post Share on other sites More sharing options...
AkakmanH Posted September 25, 2016 Posted September 25, 2016 Besides all of the above, many new MB will not start unless you have keyboard, mouse and HD plugged in. Not right, but some do it. Share this post Link to post Share on other sites More sharing options...
alyusha Posted September 27, 2016 Posted September 27, 2016 Well, I set it out and plugged in another PSU. 24 + 8 with CPU + HS and it all still blinked. I guess it is just dead. I dunno. Share this post Link to post Share on other sites More sharing options...
SpikeSoprano Posted September 27, 2016 Posted September 27, 2016 (edited) Did you pull out the memory sticks to reset them ? There are a lot of things that will stop a mb from posting , so don't jump to a conclusion too quickly, also did you reset the cmos or pull the battery ?

The amount of times I had a motherboard not start after pulling something out is like 100+ now. Start with what you know. Everything worked before so you can eliminate a few things. If no lights are present on the motherboard. Because usually like a standby light is on or something indicating power. Than again not all of them have this. Semi not in order list 1: Check Power jump PSU, or a power light indicator. 2: Check power cables to MB. 24PIN, 8PIN, 4PIN, etc 2: If your motherboard has a power button the board itself, try it out 3: If not check the wires to make sure the IO cables aren't pulled out (very common) 4: Check for a short, like a dropped screw floating around 5: Reseat the ram 6: Reset the CMOS 7: Ask OCC for help!
