Hi Essence22,

First of all- welcome to our site!

We don't work on technical problems in this particular forum, but I'll move your post to our Troubleshooting Dead Machines forum so that our technical troubleshooters can help you out

Start with the basics.
Test your memory first. Run a memory test utility like memtest86 while your memory is installed or remove your existing memory and install known good memory into only one DIMM slot at a time. If your memory passes, check for loose or unseated cards in the computer, loose cable connections, and make sure your power supply is putting out the proper voltage. Look at the most recent changes to your system, both software and hardware, and try to remember if the problem started shortly after making any of the changes. If all these items check good and you are sure your computer is free of any virus or spyware, check the programs loaded during Windows startup. You can see the programs loaded by clicking on "Start" then "Run" and typing "msconfig" in the command box. A window will pop up showing the Windows startup options. Select the Startup tab and review the programs that load when Windows starts. If anything doesn't look right, you can uncheck it or do a google for the process name if you are unsure. You can also uncheck all the processes and restart the machine to quickly see if any of the startup programs are causing the problem. If the problem goes away, then add the start up programs one at a time until the problem returns. The last one added should be the cause.
