Please log in for more thread options It's been running fine for the last few months but all of a sudden I can't get it to stop restarting. Sometimes I can get as far as logging on to XP and other times it only gets as far as the loading screen before a blue screen <Shudder>
flashes up, too quick to read.
I checked the bios and the CPU is running at 65-75 degrees!!!!! I've tried swapping the RAM round and replacing it with some spare but it doesn't seem to affect it. I've only built a few (4/5) pc's before but have never seen this problem before. I haven't changed any h/ware at all. The only thing I can think of is that I think we had a power cut a few days before but can't really see this having any affect? Please help...

As McGrumpy wrote, a failed/failing CPU cooler fan is a definite possibility. Another possibility is that the cooler has loosened somehow and is no longer making good contact with the processor. Also, you might want to make sure that all BIOS settings are at their safe default values -- I've had at least one system brought to me where the processor FSB was "mysteriously" cranked up and the system was being overclocked by 15-20%. The owner denied doing the deed and it amazed me that the P4 was able to run at that speed with standard core and memory voltages. But it sure was running hot enough to cause all manner of erratic problems and shutdowns. -- John McGaw [Knoxville, TN, USA] http://johnmcgaw.com Reply Skinner.Da...@gmail.com Sep 12, 10:25 am show options Newsgroups: alt.comp.hardware From: Skinner.Da...@gmail.com - Find messages by this author Date: 12 Sep 2005 02:25:38 -0700 Local: Mon, Sep 12 2005 10:25 am Subject: Re: CPU started overheating for no reason.

It might help if I could see the blue screen before the system reboots, any idea how I might manage that? Have thought of maybe turning off overheat protection on the BIOS so I can have just long enough to read the blue screen. Am really pulling my hair out with this. Is it possibly something to do with the PSU or Mobo being shagged?

That should be pretty easy: right click "my computer" > properties >
restart".
advanced > Startup and Recovery settings > uncheck "automatically But all along some sort of error data should have been dumped to the system log although sometimes it is not as useful as one might want. As in many log entries are pure gibberish unless you happen to be the programmer who wrote that module. -- John McGaw [Knoxville, TN, USA] http://johnmcgaw.com Reply Skinner.Da...@gmail.com Sep 13, 10:55 am show options Ok, sounds good but I can't get that far, it normally restarts just as it brings up the windows loading screen with the coloured line going across under the win logo. The temp is about 65 - 75 ish in BIOS! Cheers Skinner | ||||||||||
