need bb Posted April 12, 2007 Posted April 12, 2007 I have been having some issues with my computer. It has been working great for the past 3 months, but recently is has started randomly shutting down. I have reset the bios to the defaults so the issues doesn’t relate to overclocking. Additionally, I know the machine is not overheating as I have some heavy duty cooling which keeps it at -10C. All the other temps and voltages while the machine is running are within spec. Once the machine shuts down, and I try to start it up, it powers on for 1 second before shutting down. These seemed like a PSU issue, even though my PSU has been rock solid. I tried disconnecting all the drives, and used an ATI X300, but the machine still shuts down. I tried another 500W PSU that I use in my ABIT NF4 system, and the machine had the same issues, so I know it is not PSU related. I have also narrowed down the problem to occurring when the machine is stressed. When I run Prime95, the machine only lasts 2 minutes before shutting down. The machine also shutdown when it is not even running an OS, so it is some hardware issue. I am out of ideas, on what is causing the issue, so does anyone have any ideas?

stepbackjack Posted April 12, 2007 Posted April 12, 2007 Try with the side off, perhaps your card is heating up, but I think your short on the power side with that 500 watt. I would have matched the antecs 650 trio with your rig. Share this post Link to post Share on other sites More sharing options...
need bb Posted April 12, 2007 Posted April 12, 2007 I did try it with the side off, and it didn't help. I know its not a power issue as I have been testing with 1HD and just an ATI x300 which draws hardly any power. Share this post Link to post Share on other sites More sharing options...

signmeuptoo Posted April 16, 2007 Posted April 16, 2007 You "KNOW" it is not a power supply issue? How do you KNOW? A supply can show even normal voltages and still be working wrong! I had this happen to me! I'd buy a power supply tester from frozencpu or newegg, the one with the LCD, and REALLY test it. Also, PCP&C sells a supply tester that applies an actual load, both are recommended for full testing. I would have to suspect your supply or a dieing motherboard or RAM. How high a voltage did your run the RAM at? Is that the Ballistix that has Micron 5B in it? If so I hope you didn't go too high on the voltage..

Sharp Posted April 16, 2007 Posted April 16, 2007 Hello, When running P95, what are the temps? CPU = PWM = CHIPSET = Share this post Link to post Share on other sites More sharing options...
need bb Posted April 17, 2007 Posted April 17, 2007 Well I have tried my other 500W PSU, that I use in my other NF4 system. I am currently using the "other" system and it has been rock solid, so if the PSU works fine in a similar system, I imagine the PSU is fine. I was running the memory at 2.7V, but it has been at 2.6V since I have reset the bios trying to track down the issue. As for temps during PM95: CPU = 0C PWM = 40C CHIPSET = 35C Share this post Link to post Share on other sites More sharing options...
signmeuptoo Posted April 17, 2007 Posted April 17, 2007 The CPU *CAN'T* be 0 degrees, perhaps you should try a different temperature monitoring program... Share this post Link to post Share on other sites More sharing options...
krazypoloc Posted April 17, 2007 Posted April 17, 2007 Are those Z503's? If so I know the answer.................. Share this post Link to post Share on other sites More sharing options...
HITandRUN Posted April 17, 2007 Posted April 17, 2007 Look at your Ram (2x1GB Crucial Ballistic PC4000 --> famous for dying) Run a memtest from the BIOS and tell us if you pass 8hrs. If yes that come back and we think about something else (like the psu) Had the same ram and it died after 2 months! They clock like nothing else there but they start showing errors quick as well.

need bb Posted April 17, 2007 Posted April 17, 2007 They are the Z503, but they are the new revision with 5B F chips. My CPU temp is correct. It runs at -20C idle and around 0C load. Share this post Link to post Share on other sites More sharing options...
Coors Posted April 17, 2007 Posted April 17, 2007 What cooling do you have...a mach 1 or something? It might help if you list that in your sig as well. Share this post Link to post Share on other sites More sharing options...
