Basically I got a new PC with faulty RAM and after I asked them to replace it, they told me it was fine.
I've decided to just replace it myself, any suggestions on what sort of thing I should look for(price range upto about £120)
I'll post my computer spec later.
Nope I never ran a memtest per stick
I'll have to post the PC spec in about 30 mins as I've been busy all day
