Hey everyone, I am very familiar with troubleshooting products and usually can fix most things but, well, here is the story. Last year a guy sold me his Alienware R4 17 (i7 7700HQ GTX 1070) and in the beginning, there didn't seem to be any issues except one USB port wasn't particularly stable. I started using the USB C port and the Thunderbolt in the back of the unit to perform most of my USB needs. One day, I moved the unit from a place of the house to another, when I tried to plug in any USB device, nothing would happen. The only port that would work is the thunderbolt port. So the troubleshooting nightmare began, Checked Drivers and device manager = USB xHCI Compliant Host Controller error Tried to update it = nope Reinstall windows = nope and could not use the ports for USB boot either. update bios = it is updated but I can't reinstall it because new problems appeared. Now, the system will not shut down completely, it does shut windows but the lights stay on = need to force shut down When I restart it, = it shuts down Alien FX lights stay on and the software cannot control it anymore Now, I took the device apart and checked for anything unplugged and decided to reset the CMOS, removed the battery and = still the same issues I called Dell and according to the tech guy, I need to buy a new motherboard for 1600.00 USD. I thought, wait a second, the laptop works with everything else. The GPU is solid, CPU is great, all ram is fine and the display is perfect. ALL ssd's and hhd slots work with no issues. Now I am wondering if there a possibility of having whatever is controlling that port repaired or chip replaced instead of a new motherboard. I figure that Dell would basically give me a repaired motherboard and fix this one and resell it. So my question is what do I do? Do pc repair shops replace components on a board? Should I just sell it for almost nothing or do I pay almost twice for the product? By the way, yes the warranty is out and the guy who purchased it doesn't have the receipt. Thanks for your responses.
