Hi guys,

i have a MOBO 10 Years old model DZ77BH55K, great Intel Motherboard last of its kind, still going good except for a strange problem, this belong to intel 3rd Gen, an year back i have empowered it to handle NVMe, by extending the secondary PCIe slot to accommodate a NVMe PCie converter which housed a 512GB SSD, it was fun for an year as i was so proud that i upgraded this mobo to a NVMe compliant device... But all of a sudden all the PCie express slots stopped working, but the mobo is still going on, and i am using a i5-3570 proccy, which has in processor GPU that let me go on.. i am wondering is it possible to repair the PCiE slots to make it work back.. Your thoughts and practical suggestions please..
 
The first thing I would do is perform a BIOS reset. If nothing changes, try re-seating the CPU. Also, check the CPU's contact pads for any rust/dark spots. If there's any, clean them with IPA and a cotton swab gently. Good luck!
