Constant lag and BSOD on shutdown

[BigGreenBudz]

laptop : hp pavillion dv8225nr

Ive had this laptop for years, a few years ago windows became nearly unusable due to lag. A Linux live CD told me the hard drive was failing. Recently i decided to replace the hard drive, but it doesnt really seem to have fixed anything, Even closing all programs and only opening 1 browser, i can not fluently stream a podcast, or watch youtube videos. The laptops old, but i did all those things on it before. Even while typing this 1 out of 10 buttons doesnt seem to register. Also, every time i shut down i get a BSOD saying:
bcmwl5.sys - Address F6D6E7CC base at F6D5C000, Datestamp 4e5ee1c0
*just read i might be able to fix that BSOD with a driver update*

Ive tested the RAM with memtest, a 17 hour test had no fails and i backed out of the test.

I dont know what else to do/check? any advice would be appreciated.

Also, i decided to install fedora linux on a 2nd partition to see if it ran correctly,

this link said they could not find your product at hp

go to the above link and enter your info to try and find the correct driver

===========

The file that is causing the problem bcmwl5.sys is a driver file for a Broadcom wireless device. I would suggest uninstalling the Broadcom device and remove all accociated software. Get the latest software\drivers from Broadcom (do this before uninstall if it is your only access to the internet). Then reinstall the device drivers and software.

===========

once the blue screen is resolved we can work on the lag problem, which can be malware, defragment needed

what is your current antivirus?

do the following to insure a clean pc:

Download, install, update and do full scan with these free malware detection programs:

Malwarebytes (MBAM): http://www.malwarebytes.org/products/malwarebytes_free
SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

Remove all found, reboot, and run again until scans run clean, these can be removed afterwards if you so choose. Run scans one at a time, please.

==============

you will also need to run checkdisk, preferably from the recovery console, but if your install cd is only at sp2, and your os is at sp3, then run it from within windows.

if you do not have Recovery Console installed, then run from the start menu

go to start, run, type in cmd

in cmd type in chkdsk c: /r and press enter

type Y for yes and press enter

type exit and press enter

restart pc, allow checkdisk to finish and run again

this will take some time and the percentages will fluctuate, this is normal.
