cheers Rich
looks like a replacement is probably the best way to test it.
The case and psu only cost me £16 in the first place off fleabay
so I assume it can't be that good.
Many thanks for your help

Half decent one here for under a tenner Gaz, http://www.ebuyer.com/UK/product/101297/

that last one is about minimum spec for the motherboard probably best to use a slightly higher spec so as to avoid any overload.
or am I talking from somewhere I should be sat on?

Nope, you're perfectly right, always over-spec your PSU, soooo many people overlook this side of components!

Just a thought on this...

If it's not the PSU do you have the following:

Green-coloured 'frog' USB ASDL modem? (usually suplied by BT broadband a few years ago)?

If so, there was a driver-related issue involving this equipment that caused sudden and instantaneous shut-down or restart of a PC. It was a right b*tch to fix as evertime I tried to download the patch to fix said problem, the fault would occur and my PC would shutdown. Took me over an hour to download something a small as a few hundred K...

Anyways, needless to say the green frog soon went and is now sitting somewhere in a rubish tip....

Obviously, these are very specific circumstances and so its a bit of a long-shot....

No not a "frog" modem, am running through a d-link router. Hopefully a new psu will sort it.

A friend has reported similar behaviour from his frog, very odd!

I have a mental D-Link router it occasionally drops DNS on any port I have this PC connected to.

I use a static address for this one, net result the outside world slowly disappears it is probably something to do with this PC as my half dozen or so other machines using DHCP don't have the same problem yet no amount of PC reboots clear the fault, I have to bounce the router

Probably an ARP issue and I am losing the gateway but it does not happen often enough to warrant too much digging

If your fault does turn out to be PSU and not memory or a jumper in the wrong place causing an instability, have you reset the Bios to tortoise values? then go a for a nice temp controlled PSU then the fan should hopefully run a bit quieter

Gary - is your machine using Windows 2000 Professional?

My Windows 2000 machine does this regularly (about once a day) and two other Win 2000 machines do exactly the same thing. All three machines have completely different components and are in different houses, so the only common link is the operating system.

I've reformatted and reinstalled everything and it makes no difference. I built the machines at different times using components from these manufacturers:

Motherboards: Epox, MSI, Asus
CPUs: AMD, Intel
Power Supplies: Novatech, Akasa, Zalman
Memory: Samsung, Kingston, Twinmos
Fans: Akasa, Zalman
Graphics: Powercolor, ATI
Sound: Creative Labs, Novatech
Hard Drives: IBM, Hitachi, Western Digital
Optical Drives: Pioneer, Lite-On
Modems: Alcatel, Novatech

Make sure you have downloaded and updated all Drivers & Windows Updates, just in case. Drivers can often cause this if their not written for the operating system you are using. Bit out of touch with 2000 now but will check our fault database later and report back if there is any indicators.

Other Normal Faults for Shutdown are: Power Supply, OverHeating, Broken Fans, Build up of Dust in Vents, Missing Microsoft Updates, and the 2 Most Common: Virus and Spyware for shutting down system.
