I doubt the "shop" will take responsibility but card has a 3 year warranty. But before you call them:
1. Take out the card .... make sure to hit the release lever that locks the card in place before yanking on it.
a) Remove 8 pin cable
b) Remove the 2 slot screws
c) Hold down release lever while pulling the card out of slot. Prolly a youtube video if ya wanna see how its done.
2. Examine the card:
a) Try moving the fans with your finger ... do they rotate freely / Do they rub against the shroud ?
b) Are the fan connectors connected ? You can see them here on far right (white with yellow, red, black wires)
c) Check to make sure heat sink / shroud is firmly attached
d) Clean all contacts with isoprophly alcohol (90+%) or contact cleaner. use a foam swap if you choose to clean slot contacts.
3. Correct any deficiencies from above.
4. Replace card in slot making sure that you hear a good "click". Insert screws and connect 8-pin cable.
5. restart system ... if fans no go, call MSI tech Support. After walking you thru some troubleshooting steps, they will give you an RMA is card is still not working.
