OK now I'm going to look into some serious hardware possibilities now.
First I would like you to run a all night memtest on your system .
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...
1. Download - Pre-Compiled Bootable ISO (.zip)
2. Unzip downloaded memtest86+-2.11.iso.zip
3. Inside, you'll find memtest86+-2.11.iso
4. Download, and install ImgBurn
5. Insert blank CD into your CD drive.
6. Open ImgBurn
, and click on Write image file to disc
7. Click on Browse for a file...
8. Locate memtest86+-2.11.iso
file, and click Open
9. Click on ImgBurn green arrow to start burning bootable memtest86 CD:
10. Once the CD is created, boot from it, and memtest will automatically start to run. You may have to change the boot sequence in your BIOS to make it work right.
To change Boot Sequence
in your BIOS
Reboot the system and at the first post screen (where it is counting up memory)
start tapping the DEL
This will enter you into the Bios\Cmos
Find the Advanced
area and click Enter
Look for Boot Sequence
or Boot Options
and highlight that click Enter
Now highlight the first drive and follow the directions on the bottom of the screen on how to modify it and change it to CDrom
Change the second drive to the C or Main Drive
Once that is done then click F10 to Save and Exit
You will prompted to enter Y
to verify Save and Exit
. Click Y
and the system will now reboot with the new settings.
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.
