Looking at upgrading RAM, looking at getting one stick of 512Mb PC2100 (PC266) DDR Memory, with a ABIT NF7 mobo, is it compatible??

Thats the link to compatible hardware for that board.
As far as your memory is concerned, even if its not listed there it should run alright

Thanks!

Nae bother m8

Could my current RAM be the cause of my PC crashing?

Depends on what the crashes look like ?? Spontaneous, at random ? Or if u do certain things ?

Must point that I have a new processor too.

It is crashing while

burning a photo CD

manipulating images

burning a music CD

uninstalling an application

Not crashing

Whilst surfing the web

downloading

clean ups (Spybot, Ad Aware, NIS 2005, Crap Cleaner, Reg Scrub, Diskeeper)

Playing a game, however it's a low spec required game, so maybe need to try something else.



Crashes the PC switches off and goes "nee naw - nee naw" siren type noise

The two-tone "siren" beep code is normally the BIOS's 'CPU Overheat' alarm, though it may also mean that the voltage settings are wrong. Run the system with the side of the case off so that you can check that the CPU fan is running properly. Surfing the Internet and downloading files are not CPU-intensive operations, whereas uninstalling applications and burning a CD are relatively intensive so that does tie up.

If it's a voltage issue, you'd normally get the siren beep code when you switch the PC on, whereas you'd expect the CPU to only overheat after you've been using it for a while. Still worth a quick look in the BIOS to double-check that you've got the CPU settings right though (or, if the system auto-detected it, that it detected the correct parameters).

Let us know if that helps

All CPU settings are correct

OK. Is the fan running correctly?
