Windows XP SP2 Error Messages and BLUE SCREEN!! Need Help PLZ Computer Crashes...

**I have Windows XP SP2**

Most of the time my computer wont work and when it does, it is EXTREMELY slow.....
My Desktop keeps disappearing and reappearing on random occasions..
Most of the time i have to navigate my computer through the Task Manager..

Some of the ERROR MESSAGES that keep popping up are::

*CLI.EXE-Application Error*
-The application failed to initialize properly (0xc000007b).
Click OK to terminate application.

AND

*RUN DLL*
-Error loading C:\WINDOWS\system32\memelore.dll
The specified module could not be found.


ALSO my COMPUTER seems to CRASH RANDOMLY because a BLUE SCREEN appears and i have to restart it.
The error message on the BLUE SCREEN is::

A problem has been detected and windows has been shut down to prevent damage to your computer.
PAGE_FAULT_IN_NONPAGED_AREA
Technical Information:
***STOP: 0x00000050 (0xE29c7000, 0x0000000, 0x80537c22, 0x00000001)


It also says stuff like:
Check to make sure any new hardware or software is properly installed. And ETC....
If problems continue, disable BIOS memory options such as caching or shadowing.
Use Same Mode to remove or disable components. And ETC....
Begining dump of physical memory.
Physical memory dump complete.


*** I KNOW it works because i am CURRENTLY working on my computer asking this question RIGHT NOW***

---in order for the BLUE SCREEN NOT to pop up so fast i usually have to put on a movie in the background so it "keeps the computer busy"...
Using this method i can use it for 2-3 Hours MAX.. BUT as ALWAYS EVENTUALLY the BLUE SCREEN of DEATH has to pop up!!

*Does anyone know what all of these error messages mean??*
How can I fix my computer without having to do a system restore?

Thanx in ADVANCE for any information you guys can provide and help me with!!!... :] <3

 

Hello and welcome to MajorGeeks!

Sorry to have to hit you with a lot of questions, but if you can answer these we can help you better:

1. What make and model is the computer and how old is it?

2. When was windows last updated?

3. What security (antivirus, firewall, anti-malware, anti-spam etc) software are you running, when was this last updated, and when was the last scan (if applicable)?
