Ok, so today I cleaned out my PC for my bi-monthly Dust free clean. Did it the same as always, then went to boot it up and chaos had hit. I was getting this constant boot loop and error message 15 (on the LED indicator). Looked it up and it is a problem with the pre-memory initialization of the North bridge. I've spent the last 4 hours trying to fix it. Nothing.Now I am resulting to here before I send the $540 mobo away under warranty.The motherboard is a Gigabyte Z87X-OC FORCE.Please help. Love my PC to bits (even though it's half finished).Let me know if you need any more information!
