  • Faulty power supply unit?

    I'm one of those users who tends to leave their PC on for a week or so at a time. Anyways in the last week i've just been casually using it, when suddenly it just completely hard-reboots, as if someone has press the reset button on the front of my box, except there is no reboot button on the front of my box.

    The only reason I can think for this is if the PSU is just cutting off for a split second or something. After this nasty hard reboot happens, I notice all the PC loadup crap (detecting raids, memory, processor etc) goes pretty slow and my PC is slow on loading.

    Any ideas folks?

    Could possibly be a heating issue, sure all your fans and whatnot are working?

      Well for one, maybe stop doing that?

        Nothing wrong with letting computers run for weeks/months/ages on end. Its not bad for them.

          I think it may be better for them. I leave mine on all the time, but mainly because I don't like to wait around for it to boot up in the morning.

          If it is the PSU it sounds like a overheating problem (like Zach pointed out). If the fan has died on you, remove the case from the PC and get a couple of house fans blowing on it to keep it cool until you can get a replacement. If you have spare parts laying around you can replace the fan in the PSU of course, I did this in one of mine a few years ago.

          Be careful findling inside the PSU though, there are a few places in it that you don't want to stick your fingers.

            Could be bad memory, too. I also had my computer boot up super-slow when a crappy D-Link USB hub was connected. Never again will I buy D-Link hardware. I feel dirty having a D-Link USB/Ethernet adapter connected to my TiVo.

            What's the wattage of the PSU, and what stuff do you have in your computer?

                Install motherboard monitor and keep an eye on the cpu, gpu, hd, fan rpm's, voltage, etc. The dashboard feature is great. You can also set options to warn you if it drops below x, or goes above y.

                I use it because I have my PC on. I don't even know how to turn it off. If it goes off it is because I add new hardware or there's a power failure.

                Dashboard has saved me once already when a fan went dead and rpm went to 0 and temp in the case went higher and resulted in the cpu cooling itself with warm air.

                  Nifty little program there Floris. I can't seem to find my Mobo in the MBM list though.

                  I had a quick look inside of the case and I see "MS-7185 K8n Version 1.0". After a look on the official MSI Computer Corp. website I narrowed it down to:




                  I'm pretty sure it's 1) due to the model number naming. Anwyays, my model number is not in the list and incompatible with that program. Any suggestions?

                    Hmm seems my manufacturer do their own utlity:

                    Anyways I'm taking it that if it says my CPU is running at 127 and that value isn't changing, and the system temperature is 38degrees. Surely 127degrees is a mistake?

                      127F ? I hope... Otherwise your processor is over 250F

                        It seems very strange that the manufacturers application would give false readings.

                          Are you sure its in C?

                            Could be a damaged thermal sensor.

                              I also have this, the BIOS > hardware monitor > temps show both F & C and the program shows one of my CPU's is 127, but CPU0 = the proper sensor and reads 28 degrees C, up to 35 (unstressed).
