Recently my computer would not turn on at all and I called Dell and they determined my moththerboard was bad. So I sent it in and they replaced it. When I got it back though it was full of problems. I originally could not even get it started. Constant BIOS errors that I could even get it to load windows. I had to factory reset and reinstall windows three times which allowed me to even set up a profile and log in. However I am still encountering numerous errors and issues.

I have a Dell Inspiron 15 7000 series Intel i5-6300HQ 2.3 GHz Quad-Core NVIDIA GeForce GTX 960M 4GB GDDR5 8 GB DDR3L / 256 GB Solid-State Drive Windows 10

BIOS Errors I'm getting that I have gotten just today in the last two hours:

DRIVER_IRQL_NOT_LESS_OR_EQUAL (aswNetSec.sys) -5 times today WHEA_UNCORRECTABLE_ERROR -5 times as well PAGE_FAULT_IN_NONPAGED_AREA -4 times MACHINE_CHECK_EXCEPTION -2 times DPC_WATCHDOG_VIOLATION -2 times ATTEMPTED_EXECUTE_OF_NONEXECUTE_MEMO RY CRITICAL_PROCESS_DIED mfehidk.sys failed

Other issues: No Internet connection over WiFi even when WiFi is working on other devices. No matter what network I use. Often it does not even see available networks. Chrome also keeps crashing all the time or get “Aw, Snap!” page. Happening constantly.

Troubleshooting I have done: I have updated every single one of my drivers. Some, like the Logitech unifying driver I had to completely uninstall the driver and redo. Run memory tests Ran chkdsk /f command prompt Uninstall avast and reinstalled

I'm not very computer savy and I have no clue where to even start on fixing these. Please, any insight would be greatly appreciated
