Yes i readed it. But i'm like 14 years so i don't know much about the whole thing what u saying sorry =P
If you have a USB stick:
http://unetbootin.sourceforge.net/unetbootin-windows-latest.exe
Run this program, once you have the ISO for Memtest downloaded.
Click 'Disk Image', then '...' to browse for the ISO image.
Make sure your USB stick is over 1GB in size.
Should look like this, with the path for your ISO instead of the Ubuntu disk shown in the picture. (forgive me for pinching images off another website).
Type: USB Drive, Drive: Browse for your USB stick, and select that. Then click OK. It should work it's magic.
Once you've done that, you'll want to reboot, with your USB stick plugged in.
You will most likely have to go into your BIOS settings. I have no idea what motherboard you have, so you'll have to be quick and try and see where it says 'Press F(something) to change settings)', or something similar.
Navigate through your BIOS settings, till you find a screen that has options similar to this:
You'll want to move the removable disc/USB drive to the top of the boot order.
Save changes and exit.
Once you've restarted it should boot off the memory stick. Run Memtest and relay the outcome here.
Best of luck.
