I see two options, AVG, or RAM.
Uninstall AVG, using AVG Remover:
http://www.avg.com/download-toolsSwitch to one of these:
- Avira free antivirus:
http://www.free-av.com/en/download/1/avira_antivir_personal__free_antivirus.html- Avast! free antivirus:
http://www.avast.com/eng/download-avast-home.html- free Comodo Internet Security (firewall + AV):
http://www.personalfirewall.comodo.com/NOTE. During installation, Comodo will also allow you to install AV only, or firewall only, if you prefer to combine one Comodo product with some other product.
If you decide to install Avast, or Avira, make sure, Windows firewall is turned
on, or use Comodo firewall..
If you decide to install Comodo Internet Security, or just Comodo firewall, make sure, Windows firewall is turned
off.
IMPORTANT! Make sure, you use only ONE antivirus, and ONE firewall.================================================================
If the above doesn't help...
A. If you have more than one RAM module installed, try starting computer with one RAM stick at a time.
NOTE Keep in mind, the manual check listed above is always superior to the software check, listed below. DO NOT proceed with memtest, if you can go with option AB. If you have only one RAM stick installed...
...run
memtest...

10. Once the CD is created, boot from it, and memtest will automatically start to run.
The running program will look something like this depending on the size and number of ram modules installed:
It's recommended to run 5-6
passes. Each pass contains very same 8
tests.
This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.
The following image is the test results area:
The most important item here is the “errors” line. If you see ANY errors, even one, most likely, you have bad RAM.
