My PC has been playing up lately and originally I thought I had a faulty DIMM slot. However I came round to thinking my 300W PSU wasn't up to it so I fitted a 450W version. Anyway, I still need to discount the memory.

I've tried a couple of memory checkers (software) but they've always passed bad memory (you know the score, the memory checkers say it's okay but Windows blue-screens!). Anyway, can anyone recommend a GOOD memory checker that intensively scans my memory (and works!) please?

might not me memory! could be bad drivers?

software memory are useless (IMHO). best way is to swap it with another PC to test it.
