I reinstalled windows and after that I installed all drivers from the official site. All my games and some applications are lagging. I downloaded dpc latensy checker and most of my posts are red. I tried to disable some devices in device manager and nothing worked. I tried to reinstall drivers, windows, update BIOS and did not help. What could be the problem? Product number: 4PS16EA#ACB
I really wish folks would STOP reinstalling Windows simply because their PC becomes slow -- because that has nothing to do with the performance of the PC, and sets you up for HOURS of Windows Updates, during which your PC will be virtually unusable.
This issue is often due to a failing drive. So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.
If not, to check the drive you have to follow these steps: 1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over. 2) Eventually, you will see an HP Startup Menu 3) Press the Function key for testing the hard drive (usually F2) and let it run.
