  • OPUS 320W, PC Freezing

    I bought a OPUS 320W last yr and stuck it on a piece of plexi and threw it in a full desktop case. Now I have intermittent pc freezing issues. Everything is working fine then I hear this electric sound in the speakers and the screen freezes. I have to restart it to fix. I thought that maybe there was a short going on with a loose wire touching the mobo, but found nothing. COuld this be a OPUS issue or is there something definetely shorting the mobo and I have to look more carefully?
    Oh why do I spend so much time and money on a technology that works only half the time? Is always a work in progress? Is never complete? I wonder.

    Probably not a shorting issue at all...
    I assume this only began when you switched PSU's? How many times has this occured in the last year since you switched?
    Did you bump any components? HSF?
    Is the 320 wired properly? Large gauge + and - cabling?
    I'd start over...check the wiring and plugs...reseat CPU/RAM/slotted cards...
    Run some stability tests with Prime95...
    Check your RAM
    Check your BIOS settings

      Well I switched PSU's and the whole mobo and case. This occurs every 2nd time I use the PC. All components are screwed in tight. And i didn't bump anything. I am not very familiar with what constitutes a shorting issue. What makes u think that this is not?

        A shorting issue is when something is forming a short circuit... like a wire is touching a ground point before the wire gets to what it is powering. This would generally cause much more serious issues.

        In the plexiglas case, are there any fans? This issue seems like it has pretty good potential for being an overheating issue.

          Actually the case is metal, and i only stuck the opus on the small sheet of plexi as there was no other way to put the opus in. Then i screwed the plexi in to the case ghetto style
          The case has plenty of air as i have it open from the top..meaning no lid! And i have 2 fans as well. But in the past when i had a CPU heat issue, it would just restart the pc, not freeze!

          By the way i know what a short circuit is, i just didnt know how a pc responds to it

            How much air can the opus get?
            What gauge of wire is being run to the power supply?
            Do you have a multimeter?

              The opus is pretty much sitting in open air with a fan next to it. I used a 12 gauge wire for power as recommended by the OPUS online manual. I do have a multimeter. Are u suggesting that I should check the power rails to see if the opus is outputting the correct voltage?

                Yeah when it freezes, check the power being supplied to it by the car and then check each of the rails too. If the voltages are all okay then it won't be the opus that is the problem.

                  Ok, will try that this weekend (or before) and will let you know. Gotta get to work tomorrow (yeesh!)

                  Thanks

                    Are you using 12AWG on ALL 3 grounds and ALL 3 power inputs?

                      I twisted all 3 power into one, then connected them to one 12 gauge and same for the ground. The wires don't seem to heat up while pc is in operation.

                        Well ok, yesterday I ran the carputer in the garage w/o any freezing. I made everything was seated in tight and all the wires were connected and not loose. It ran perfectly in the garage. Then it froze up on the first test drive!
                        grrrr. I still dont have any ideas

                          There's a reason why the Opus has 3 seperate 12AWG power and 3 seperate 12AWG ground leads...
                          I connected 2 of each to my power and ground blocks (which is fed thru 8AWG)...1 pair are twisted together...both are individually fused.
                          Give this a try...can't be that much work to do...

                            Now when you say you hear a sound, you mean like when you charge a old school flash for a camera, it makes that sound while charging? Do you have any hubs? I notice the OPUS 320 doesnt like things like Hubs being run off its 5V rail. It will freeze my PC at POST if I power any hub. I had to buy a seperate 5v PSU. My MoBo powers on the USB drives in a weird way, and powering any hubs or any device through the 5V rail will cause issues. I alot of PC freezing went away when I redid all electrical cabling with bigger gauge wire. Also checked all power cables from devices like DVD ROM and HDD and all freezing went away. Infact its rare my PC acts up. Only time I have issues is sometimes it says I do not have enough power and the OPUS will not turn on right away. This is the batteries issue though.
