i've buyed a laptop from internet, a Dell latitude E6420
Intel i5 2520M 3,2Ghz
4GB DDR3 SDRAM 1333MHZ
320GB HDD 7200rpm
I installed a fresh copy off Windows 10 64-bit and did all updates and runs fine.
When i plugged my mouse in a usb port Windows detects it but then it freezes the whole laptop.
it power off and restart.
when i did a dell diagnostic test it says ''HDD long self test unsuccessful''
i retry it, and...again same error..
errorcode is 2000-0142
i test this hard drive with crystaldiskinfo no errors!
but system freezes as well..
What can i do?
UPDATE: Clean install Windows 10 again.
No freezes , but after reboot usb and wifi wont work.
Reboot again wifi works, but usb mouse wont recognize usb mouse and all drivers work :/
Great News. Glad your computer is working now. I do suggest you run Diagnostic tool(F12key) on the computer again. Hopefully error code 2000-0142 doesn't show up again.
As given in Dell Latitude E6420 Manual, Tap 'F8' on the keyboard immediately and every one second until the Dell logo screen disappears. From there you will see the Windows Advanced Options Menu on the screen. (If the Windows Advanced Options Menu does not appear, restart the system and try again.) Select Safe mode with Networking and press Enter.
