garrettt Posted August 26, 2009 Share Posted August 26, 2009 I have the Intel DX58SO motherboard with a i7-920 CPU. I have installed TR3XG1600C9 (3 sticks, total of 6GB). Everything works great, with one exception. The system hangs when rebooting (or shutting down and then restarting). It doesn't even POST, just a hang at a black screen. When this occurs: 1. Restart system from Windows XP (or shut down). 2. System shuts down normally. 3. System starts up for about 5 seconds, then shuts down again. 4. System starts up again, then will hang forever at a black screen (no video, no POST). The work around is to leave the system turned off for at least 5-10 minutes, then it will start up fine (until the next reboot). I have tried all troubleshooting steps I can think of (including, but not limited to: reseat memory, different memory timings, only one memory stick, different power supply, different HDD mode settings (RAID, IDE), etc.). Nothing seems to be overheating that I can detect. I am not over clocking in any way. Has anyone ever encountered this or have any ideas?

Thanks, Garrett When you say the system starts and then shuts down after 5 seconds, and then starts again, that is the bios watchdog that kicks in. When the system cant start with the current settings, the watchdog resets the settings and restarts automaticly. This feature can be disabled in the bios but it probably wont help. I'm having similar problems, I have the same motherboard and memory myself. Link to comment Share on other sites More sharing options...
garrettt Posted August 27, 2009 Author Share Posted August 27, 2009 Thanks, I'll try disabling the watchdog and see if it helps (I haven't tried that yet). Thanks, Garrett Link to comment Share on other sites More sharing options...
garrettt Posted August 27, 2009 Author Share Posted August 27, 2009 After disabling the watchdog, the double restart no longer occurs. However, the hang is still present. So now it is: 1. Restart system from Windows XP (or shut down). 2. System shuts down normally. 3. System starts up again, then will hang forever at a black screen (no video, no POST). The work around is to leave the system turned off for at least 5-10 minutes, then it will start up fine (until the next reboot). Thanks again, for the suggestion. I will be trying different RAM as soon as the order arrives to rule out the memory (hopefully). Garrett Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 27, 2009 Corsair Employees Share Posted August 27, 2009 Do you have the latest BIOS version and did you load setup defaults and set the XMP? Did you also try this one module at a time? Link to comment Share on other sites More sharing options...
garrettt Posted August 27, 2009 Author Share Posted August 27, 2009 Yes, I have the latest BIOS (v4196). I have tried the memory in all combinations (single, dual, and triple). I have reloaded BIOS defaults (several times) and even removed the CMOS battery and let the machine sit (as recommended by Intel support). For the memory timing settings, I have tried automatic, XMP, and manual (XMP with slightly reduced voltage). In all cases, Memtest86+ has not found any errors. I have ordered different memory (1333, another brand), just to rule out if it is a memory issue (should be here early next week). I'm open to any suggestions and appreciate the help.

Corsair Employees RAM GUY Posted August 28, 2009 Corsair Employees Share Posted August 28, 2009 NP Please let me know when you get the new modules. Link to comment Share on other sites More sharing options...
wheatfix Posted August 30, 2009 Share Posted August 30, 2009 I have the same problem. Sometimes the board does not POST on boot (or reboot) and hangs on a black screen before anything appears on the screen. I usually have to turn off the p/s and press the Power button until all the voltage drains from the board, wait a while, and then it will boot.

Corsair Employees RAM GUY Posted August 31, 2009 Corsair Employees Share Posted August 31, 2009 That might suggest it is a Board issue but let's try replacing the modules to rule them out, please use the On Line RMA Request Form and we will be happy to replace them.

wheatfix Posted September 16, 2009 Share Posted September 16, 2009 I replaced the memory with the same part number, and now the problem is gone. Thanks for your help! Link to comment Share on other sites More sharing options...
