laptop unresponsive and laggy to the point of locking up

Did you do all the other Troublesbooting steps including updating or reinstalling the display driver, check for overheating, clean boot?

i did the troubleshooting, went through device manager while latency checker was running, and i found out if i roll back my driver for "Intel PRO/Wireless Network Connection" which i think is my wireless internet chip , and the latency went from 6000 to 1900. so i guess the issue was the newer driver. The driver installed was from 2010, now rolled back, 2008, and works just as well, but latency is way better (i dont care how old the driver is, as long as it works best ). i went through other things that have to do with Bluetooth and network, and nothing else changed the latency, yet when i turn all wireless connections off (i have a switch on the side of my laptop that turns off ALL wireless connectivity), latency goes down to 500, and maxes out at 1200. but its WAYYY better than it was. ive updated all software i have installed, did clean boot, (i do that anyway, no need for all the extra stuff at bootup), and i constantly monitor my temperatures, CPU cores never goes above 170 oF, if they do, its when im working it brutally hard. usually hovers between 119oF and 131oF.

The intel ProSet driver is horrendous. You may be having a driver conflict. Do a search on how to find "hidden devices" in device manager (a preliminary step must be taken), and uninstall the grayed out drivers you don't need. Then reboot.

Change to Ethernet adapter with wireless turned off and disabled in Device Manager to compare performance.

If you further confirm wireless adapter as the cause, try all drivers stored at Device Manager>Network Adapter>Wireless Adapter>Update>Browse>Let Me Choose. Then using Ethernet uninstall any Wireless Drivers in Control Panel>Programs and Device Manager, Enable hardware auto-updating via Windows Update (Steps 3 and 6), check for Updates, install all Important and Optional Updates to be sure to get all drivers and patches for your wireless adapter and software.


If all of these fail, your wireless adapter itself may be failing. You can try reinstalling it in its port under laptop, or replace it.

haven't posted in here for a week. did a clean re-install of Windows 7 Ultimate 32-bit, and now i'm having issues with hardware interrupts. sometimes it will be taking only 1% of the CPU, and then randomly start taking 48%. I looked everywhere and most of them say a bad driver. So i went through ALL my drivers in device manager, updated them, rolled them back, no difference. BUT, i think i may have a bad graphics chip driver because my display will blink black with white lines going across the screen at random times. i have looked for a week for drivers that work, and can't find any. at this point, i'm stumped...

i just looked, and nothing is grayed out in device manager.

ill take a look, i did rebuild this laptop with another motherboard, maybe i didn't seat the WiFi adapter in correctly.

ok so figured out the issues with drivers and stuff, now runs mint. but now ( da dat daaa!) i cant install a newer version of directx! WTFUDGE!! i went to play need for speed world and it said no directx device found. so i went to download directx 11, failed to install, along with 10 and 9. so what do i do now?

(i know this is getting ridiculous, but i dont know why all this is happening.)

Did you try Manual Download? How to install the latest version of DirectX
