Really difficult to diagnose without spare parts to swap in and out, is your supplier local? perhaps you need to talk to them. The danger is you end up replacing everything one part at a time trying to find it. I've always got multiple machines and I've taken to making sure they are always compatible enough to swap parts between, because otherwise fixing faults at home is mostly guesswork (even if it's educated guesses)

Usually RAM using auto settings is fine, clocking slower than rated should not be a problem and is fairly common - my i5 sets my 1600 RAM to 1333 by default and works perfectly. Also are you using onboard graphics or a discrete card? if it's a card take it out and test with onboard.

1275557 2012-05-15 23:30:00 Looks like CPU to me. pctek (84)
1275558 2012-05-15 23:41:00 I have tested the RAM in the other slot and the results are still the same. I do want to try some different RAM, but I bought the parts from an online only shop, so I doubt I'll get help from them.
Maybe I'll try borrowing some...

I am using the onboard graphics right now, no graphics card is installed.

If this is a CPU problem, are there other clues to why it might be so? Or is the funny screen output the results of that?
I really do hope it's just RAM issue though, cheapest to solve.

1275559 2012-05-16 00:12:00 where did you get it from, NZ or overseas online shop? Iantech (16386)

1275561 2012-05-16 00:24:00 It could be significant that the BIOS displays OK - presumably for hours? - but stressing the memory gives probs. The fact that BIOS displays OK suggests the MB and CPU are OK doesn't it? (I'm only a dabbler)

I once had a memory problem that caused crashing before Windows started loading, particularly on cold mornings. MEMtest showed fewer and fewer errors as the computer warmed up. I took the memory back to the (physical) shop and they couldn't find anything wrong with it. But they gave me a good deal on replacement memory which worked fine

1275562 2012-05-16 00:34:00 NZ online shopThen you should get good support. But you need to check what you can first. See if you can borrow some memory to try - or put your memory in another system (a friends?) and see what the result is. Thats the first step. Its not unusual to get faulty hardware from new, I had a brand new gigabyte board do similar last week. Iantech (16386)
1275563 2012-05-16 01:13:00 Where in NZ are you?? Maybe someone near you, can help you out. Are you using the onboard video or a separate card? Speedy Gonzales (78)

Not always - Just finished a Persons PC this morning, it ran memtest OK ( clear as), and the BIOS was working and showing fine. Wasn't till windows booted that all hell broke lose lol. All sorts of strange images on the screen, replaced the graphic card after testing it on a workshop PC and it was fine after that.

1275565 2012-05-17 07:49:00 Thanks everyone for your input, turns out it was bad RAM.
Tried a new stick of RAM and now the computer works perfect.
Luckily the shop is happy to refund without asking too many questions.
