CPU hitting 90 degrees & system rebooting

    My five year old Medion was constantly rebooting & through burning myself when I put my hand on it one day & thought it was a heating issue (although I changed the PSU last year).

    I installed everest & discovered that the cpu was running at mid 80s, even with the side off the box (still rebooting).

    It's very dusty in there so I got a can of compressed air & a vacuum & did a blast & suck on the inside. Put the side back on & running everest again & the CPU appears to be running at 60 - 65 degrees. So I'm guessing the CPU was fairly clogged with dust causing it to overheat.

    Would this be right or am I likely to be days/weeks away from a failure ?

    What's a normal tempreture for it to run at ?

    Depending on the CPU that 60-65 degrees should be ok. I would definitely keep an eye on it over the next few weeks, and every month or so get out the hoover.

    If it's a Pentium 4 then the original ones did run very hot. I had a P4 with a decent heatsink and fan and it idled at about 55-60. Giving it a clean every couple of months should keep it within acceptable temps.

    Indeed just keep dust off it. For the terribly ambitious you might try heading to a DIY store and look for some dust filetering sheets, line that along all the PCs major access points, should keep it cleaner longer.

    Well that appears to have done the job. PC has been on almost continually for the past couple of days (downloading & in use). while in use I've been monitoring the temp & it's rarely risen above 72 with the side on. I do have a more powerful CPU & I'm guessing more powerful fan, which I might install to keep it cooler still.

    If you want to go one further, you could also reapply the Thermal Paste that sits in-between your CPU and the Heatsink. Paste only costs around a tenner - the only trick is knowing how much to use and coating it evenly. A good quality paste job could bring your temps down even farther.
