578428	2007-08-08 23:51:00	the UPS should regulate the current/voltage and provide a "perfect" stream of power? not necessarily so. only interactive UPS's will do that. the cheaper type are simply a backup UPS and will not do anything untill there is a power cut. btw what size UPS? brand? i don't know the brand of PSU, i'm a enermax fan, but i have other brands that have worked well. the other thing is to actually check the power voltage. i know of cases where the voltage was to high causing lots of appliances to die.	tweak'e (69)
578429	2007-08-09 00:00:00	btw what size UPS? brand? Dynamix UPS-650D Line Interactive, 650VA UPS. Shouldn't that be enough? the other thing is to actually check the power voltage. i know of cases where the voltage was to high causing lots of appliances to die. That's why I plugged the voltmeter into a couple of power sockets - never got more than 23xV.	jackwass (12442)
578430	2007-08-09 00:44:00	Dynamix UPS-650D Line Interactive, 650VA UPS. Shouldn't that be enough? imho a bit low. depends a lot on if you have monitor pluged into it as well. if you had a CRT monitor running through it as well then it would be way to small. ideally you need around 1000VA.	tweak'e (69)
578431	2007-08-09 00:50:00	Had a very similar problem a couple of years ago - took damn ages to locate the problem. In the end it was something weird about the case, the PC was doing exactly what yours is. I removed all the components, from the case, put them back together on the work bench, and it ran perfectly. Reconstruct back in case and instant trouble. Changed case and all OK, something was causing a short on the components. :badpc: Worth a crack if you are prepared to put the PC together out side the case.	wainuitech (129)
578432	2007-08-09 00:50:00	imho a bit low. depends a lot on if you have monitor pluged into it as well I have never had anything else plugged in at the same time (to avoid that problem). Surely this can't be the problem if the computer is acting erratically (or not turning on when it did before) - if the UPS is providing the same power it did yesterday, which is what it's for, why should the computer not boot today when it did yesterday? Unless the PSU is dodgy? Had a very similar problem a couple of years ago That sounds like the sort of weird undiagnosable problem that I thought it might be. I got the computer built for me so I would rather not start ripping it apart and interfere with my warranty/guarantee rights, but I might suggest that to them. If the computer does boot later today then it is exactly the same problem that I had before, which would rule out the PSU unless the new PSU had the same problem. I never trusted the case once I actually saw it...	jackwass (12442)
578433	2007-08-09 01:21:00	Personally I don't think its the actual power supply. 1 Power supply faulty - sure, 2 Power supplies giving the exact same problem - Not unheard of but unlikely. or VERY unlucky.:badpc: While the problem I had may be different to yours I ended up changing every single damn part before the only part left was the case.:badpc: :confused: This might sound a strange question BUT does it play up when the air temp is hotter ? eg: more in the afternoon than morning/night- what I'm getting at is when parts expand ever so slightly due to heat they may be shorting ? PS: you may also have a faulty Motherboard. PSS: I have also had it where the Power Button / Rest button are not seated correctly in the case and they cause problems.	wainuitech (129)
578434	2007-08-09 04:41:00	Power supplies giving the exact same problem - Not unheard of but unlikely. or VERY unlucky. I would've thought so too. Except I haven't been able to start it up again yet, so the problem isn't the same YET. does it play up when the air temp is hotter ? ... I have also had it where the Power Button / Rest button are not seated correctly in the case and they cause problems. It failed to start up this morning (definately not warm!) so I haven't seen that pattern. As for power button, I thought about that but that wouldn't explain the random shutting down I had before or why in the morning (for example) it wouldn't start up however much as I tried but would in the afternoon. It has to be either the PSU, case or motherboard doesn't it? That's why I was heading towards just getting a new case and PSU. But then it could still be the mobo which would be very annoying.	jackwass (12442)
578435	2007-08-09 06:46:00	Thats a weird problem alright. :confused: There is a way to see if its the Power Button / reset (I'm Very Reluctant to advise this - so I wont).You don't want to go voiding your warranty by tinkering around inside, so I'm not to keen on giving advise on how to test the power buttons etc. Some of them are very touchy, and simply the vibrations of walking past the PC can cause problems if they are faulty.( had it happen a few times.) If you want me to tell you how I will but you have to be REALLY CAREFUL. Quote: I got the computer built for me so I would rather not start ripping it apart and interfere with my warranty/guarantee rights, but I might suggest that to them. If no one else can come up with a suggestion then I would take it back to the shop you got it from and tell them to fix it - thats a warranty job if I'e ever seen it.	wainuitech (129)
578436	2007-08-09 06:47:00	Meg peeks out from behind door and mumbles to herself....... I hope it's not the PSU; I just bought a new Raidmax 520........ I thought they were a good brand.... :( :( :( :( :(	meg_h_nz (6960)
