Solve : PSU 12V Rail Stress Test? |
|
Answer» I need some suggestions for programs that will take my CPU and GPU to maximum load and hold them there. Now this may sound a little strange but I want to disprove that I am in some way overloading the 12V rail of my power SUPPLY. There should be no way that I am exceeding the limit but I would be happier if I could rule it out. That would be an impressive bug considering that I've had this problem long before I owned Skyrim and infact before it was released. Ah, I misread. I thought it happened when you made snow-angels in Skyrim. So what's the temperature at when it reboots?Quote from: Raptor on January 10, 2012, 11:57:22 AM Ah, I misread. I thought it happened when you made snow-angels in Skyrim. No idea, the system (generally) hangs on a garbled screen with a skyrim induced crash. So a temp reading is impossible. Not that it's a concern as I have stress tested the CPU and GPU for overheating issues. There are none. Quote from: PATIO on January 10, 2012, 11:31:23 AM How did you determine the RAM is fine ? ? Memtest I think was the name, one of these boot time test programs. Passed several RUNS flawlessly. On a side note though with Skyrim, the only surefire way I have of reproducing the problem, the reboots/freezes get progressively worse the longer that I attempted to run the program. Sounds like a temperature problem doesn't it? But it's not, unless the power supply was overheating and becoming unstable but you tend to notice the unmistakable smell of burning plastic during these events. Also reboots can occur at random, I turned the computer on once and after 15 minutes it rebooted on the screen saver (it had only been left to idle).Quote unless the power supply was overheating and becoming unstable but you tend to notice the unmistakable smell of burning plastic during these events.When I took my exam that was NOT one of the right answers for determining Power Supply performance.Tried updating all your drivers? Quote from: Raptor on January 11, 2012, 05:03:09 AM Tried updating all your drivers? I think that I have tried almost every driver ever written for my hardware, including a few different BIOS's. Quote from: Geek-9pm on January 10, 2012, 07:43:13 PM When I took my exam that was NOT one of the right answers for determining Power Supply performance. My point more over was that a heat related instability could raise the temperature of a PSU to easily above 100°C and would be quite hard to miss. (Not that I haven't known "experts" that have missed melting PSU's)A good PSU has a thermal overload as well as current overload protection. And even an old-fashioned fuse. If you really think the PSU is causing upset, just try another PSU. It is very, very unlikely that two PUS's, each a different model, would ever have a rare undetectable instability. (A quirk so quick you don't see it.) Also, to really test a PSU the proper method is using analog monitoring with a recording device. Which can be another computer with an external device suitable for the job. Something like this: http://blog.makezine.com/archive/2006/11/scopeonpc-turn-your-pc-in.html |
