My name is Saurabh.
Kindly try the following steps:
1. Run Pre Boot System Assessment (PSA) diagnostics to check for any hardware issue. To launch the PSA+ diagnostics on this system, Turn on the system, press <F12> at the initial Dell™ logo screen, and select Diagnostics from the boot menu.
2. Also shut down the system and remove the battery & adapter cable. Hold the power button down for 20 seconds continuously to release the flea power. Connect the adapter cable only, start the computer and tap space bar repeatedly. “Delete Restoration Data” if you get that option.
3. Try uninstalling the anti virus from the computer and then restart to check the performance.
Thanks & Regards
