David, just upgraded to a netgear dg834 g wireless router, built in firewall,

That may be your problem, conflicts between XP firewall and netgear. Worth a call to Netgear helpline probably. Mines a D Link and thier Customer Support was excelent

TP, could be a number of causes unfortunately. Faulty case or CPU fan, faulty memory, faulty motherboard, faulty power supply! First step is probably to check the case and CPU fans are spinning OK and see if anything that you do is causing it to shut down. How does it 'shut down', similar to power off with the fans stopping?

kayak just turns off in the blink of an eye to a black screen, no slow shut down procedure, i think i must have a corrupt file, closed down when i was logging onto the net this mornign so fresh machine, did it yesterday when i clicked on sharescope to load, fans all running as far as i know, how i hate computers! when they go wrong!

Only once today, been ok since!

What operating System, TP?

windows 2000 pro d2k

Pro LOL!!! :-)
All it was, was the problem you describe is similar to one I had on Win98 a few years ago,

If it shuts down suddenly with a blank screen and the fans off, leaving you to turn it on again with the power switch then it is going to be a hardware problem. Not much to go on apart from opening the case, checking the fans, and trying to swap the power supply in case it is that.

You could download MBM 5 which will give you motherboard and CPU temperatures and voltages: http://mbm.livewiredev.com/. However it will require configuring. If you look in your BIOS it may be that there is a screen giving the same information, although not in normal running of course.

You cannot beat Pros:)

thanks for the advice Kayak but a little beyond me, if it happens i will give it to my computer guy and let him loose hair over it!

"edit why has computers beome a link in my post? "

This looks to be associated with searchmiracle.com which appears to be some sort of hijack.

Unless you have deliberately installed something to do with searchmiracle.com then you should start by running Spybot S&D and AdAware.

This sounds similar to problems I had a couple of weeks ago.
Ended up with 2 new power units and on the second occasion they put a new heat sink in.Total cost was 45.the people I used are in Uxbridge Middx. If of any use to you message me and I will give you there details. Graeme.

Thanks for all kind help, will look at the link now :-)

Im getting the same problem on all 3 computers re the little explorer icon going on and on forever without actaully linking to an internet page,only happened since i installed this new router,im still trying to get the email Boyse kindly sent me, but explorer wont allow me into msn, something about cookies pops up,
Theres something in my computer that this router doesnt like, also keeps saying duplicate name on network, phoned netgear , guy got me to change a figure in the settings, still no joy, hes now saying download firmware, but i aint downloading nowt, its driving me nuts,

Hopefully Spaceman can talk me through it tonight ,if not i think i will samsh this stupid computr up and go and get a new one at weekend:-) as if i needed an excuse for some retail therapy:-)

Ruth, check that the names of all computers connected to the network are different and change if not. Control Panel/System/Network Identification.

Ruth

Best of luck. Post if you need any help.

It would be a good idea to edit your post 2324 as that contains a link to searchmiracle.com .

If you need help sorting it I can PM my phone no.

All computers were named Ruth, so ive changed 2 of them , so now different, fingers crossed:-)
Optimist, mail sent, Thanks:-)
