Bluescreen and Suddenly Slow System Please Help!!!

Hello, I'm having errors and bluescreens with my computer recently. Sometimes it will run and operate normally, others it will stop running applications, and give a bluescreen then shutdown. From reading others posts I have learned I need to give a description and a dump file, so I hope I can do both correctly. If any solutions posted please give specific directions, I am pretty good with the operating system, but fixing problems can be troublesome for me. Thanks

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 8e9daba8, memory referenced
Arg2: 0000001b, IRQL
Arg3: 00000001, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 8207ff57, address which referenced memory

A McAffee add-on crashed your system. Uninstall it. Then schedule a chkdsk scan. Also, update all your drivers. Install SP2 too.

Should I uninstall mcafee all together? and how do I schedule a chkdsk scan?

Do you have mcaffee antivirus or mcaffee addon for IE8/Firefox. Right click your drive in Explorer, then properties, tools, check now, tick both boxes, reboot.

I have a preinstall version of mcafee currently out of subscription...it will not give me the option of uninstalling my firefox Mcafee add on

Also I do not know what you mean by update your drivers...Do I have to go through them all myself or is their a quick way to do it?

Go to the site of the mfg of your computer. Find the download / support page. Type in your machines model name etc. Find any drivers that are outdated.

if the McAfee trial version has ended might as well uninstall that altogether.

What are the results?

run malwarebytes to make sure ci.dll has not been replaced.
if it is corrupted or missing, it needs to be replaced.
and not meaning to complicate things, i believe fltmgr.sys is probably what is slowing the system down.
