Toughest pc problem I've ever had...System Fan error 90b

January 23, 2014 at 00:20:46
Specs: Windows 7 Home Premium, 4gb
Bought a used HP G7 laptop. Has an error (90b) that reads something like "System fan is not working correctly. System will shut down in 15 seconds blah blah blah or press enter to continue to Windows". When the laptop is first powered up, the fan starts fine, but as soon as I hit enter to continue to windows the fan stops. I have replaced the fan, and updated the BIOS (very tricky, took laptop outside in 35 degree weather and did the update so it wouldn't run hot during). Anyone have any other Ideas? Thanks
