QUOTE(netmatrix @ Nov 20 2020, 08:53 AM) Usually the front usb port is prone to degradation. The cables used to link the port to motherboard is the one that causes the problem. There are solutions though. 1. Buy usb hub. Plug only low powered devices keyboard, mouse & printer on it. 2. Change the front panel usb ports. You can buy replacement built in usb port with 5.25 panel kit for this. Need to open the case to fix though.  Just remember back i got open post about usb Someone suggest me add this What this called? |

QUOTE(netmatrix @ Nov 24 2020, 12:33 AM) If it is standard casing, can pop out the front panel one. If it was certain model that is cut into panel DVD door, then cannot. That USB above, is USB 2.0 or can choose USB3.0? My pc currently all post is 2.0 |

QUOTE(netmatrix @ Nov 24 2020, 04:30 PM) Nahh... 2.0 is the 9 pin connector. USB 3.0 is the weird long tiny pin connector. Some sell USB 2.0 with blue connector and 9 pin port scamming people it is 3.0. But if it is cheap, no one cares la. Else get the PCIE USB 3.0 card. https://shopee.com.my/PCIE-to-USB-3.0-4Port...5320.1703222379Or the one that has the internal 3.0 connector type. https://www.lazada.com.my/products/pci-e-to...6BoCc08QAvD_BwENowdays very flexible can mod everything. I even found a PATA 2.5" with M.2 SATA SSD adapter! Wanted to try this out on an old laptop with Pentium M processors. Second one need other cable? I just open my PC 
Mean that i plug to USB2? |

QUOTE(netmatrix @ Nov 25 2020, 04:12 PM) Your board they use only half of the usb yellow connector for front panel. Usb2 pins you can plug directly to the new usb panel but it only allows 2 port type. Dun buy 4 port type. If the board maker did not cheap out, you could get usb3 pins and you get another 2 more usb ports. 😁 Just plug in, windows BSOD then long been on cpu

QUOTE(netmatrix @ Dec 11 2020, 08:59 AM) Yes you plugged in correctly. Pin 1 on motherboard with corner market cable Red(5v) - + Gnd. Exactly like the yellow USB connector. But should push the black connector all the way into the board and not exposed pins like in your picture. Look at how yellow connector is plugged all the way in. Usually if i encounter connectivity problems, a spray on the connectors from a can of contact cleaner is very helpful. It helps to remove some corrosion/dust/ oil coating on the exposed connector pins. I blow a bit on pin, then push a bit seem ok now, Got dust on pin QUOTE(RectangleX @ Dec 11 2020, 11:21 AM) Have you checked for swollen capacitors on the motherboard?
