Computer reboots itself, and shuts down, now mouse trouble.



Our computer has been giving us trouble for the past 3 or 4 months. These problems happen with XP, ME, 2000, 98SE and 95... but started in XP. Computer would shut itself off after several hours, then needed to wait at least half an hour to turn it back on. Power light remains on, and fan still runs, but computer wont work, nothing on screen (keyboard lights stay on though). It also reboots itself at random. Now the computer runs anywhere from 15 minutes up til 3 hours before it shuts off. Obviously makes it very frustrating and unreliable. Hard because I use it for work as well as leisure. We have an optic mouse (Qware) that just today started freezing. I wonder if that is causing the trouble? We have replaced power cords for the pc, checked all internal wiring, gotten a new fan, its been in the shop twice to be tested. Still it continues shutting itself off and maddening us. Any suggestions/advice?

p.s. Its not a virus, we have NAV 2001 and its up to date, do a complete system scan weekly. Have formatted, and things still continue happening.


Yes and no

we have run PC Alert and it always shows the same thing. it shows two temps, one for the cpu and one for the chassis, i am sorry i cant at the moment remember which was which. it shows that one is 22c and one is 53c. It has shown that from the very first time we ran that program, and every time since. I dont think that 53c is accurate at all, otherwise the computer wouldnt continue to work for several hours, would it?

Others here might know better but, mine runs at about 48-50C when working. Seems like if it goes over that, I will freeze. But at one point(when I goofed something up), I got up around 55 or so and it just shut down. Someone else here might have more info.


Definitely check your temperature. Check your power supply for proper voltage and current. A slight anamoly in either of these can cause the exact symptoms you're describing. Also check for malfunctioning memory chips.
