Hi guys,
Hoping for a few pointers here.

I have an MSI GS70 laptop.

After replacing my hard drive with an SSD drive and adding an extra 8gb ram chip, none of my USB ports are working.
Everything boots up fine, Windows 10 is running fine, recognises the new memory and SSD, and says the USB ports are fine. However, when I plug a mouse or keyboard into any of them, they are not recognised and are not being powered either.
I have tried removing the new ram chip and putting the old HD back in, but it made no difference. I've also cleared the CMOS by removing the battery for 5 minutes.

Cheers for your suggestions,
Stu
