    Random reboot on DP55KG system


      I have built a system based on DP55KG desktop board.

      Everything works fine apart from the fact that the system randomly reboots. It might happen twice a day or once a day or won't happen at all. The only error message I get is after reboot when Windows7 says that it didn't shut down properly.


      Below some info about the system:

          Check memory timing settings in bios including voltage setting. It might be necessary to adjust memory voltage settings.

            Did you ever find a root cause for this problem?

              Sorry to get back so late on this issue. Actually I've just solved the problem a couple of weeks ago.

              The memory modules were faulty. After trying a couple of memory test programs which found the memory modules ok, I run out of options and I just used one memory module at a time. Only one out of four modules (and it happend to be the last one that I tried) worked without restarting the computer. Logged a fault on Kingston website and they replaced all of them straight away without asking any questions. I had to send the memory to them in the first instance in order to get the new ones back. It only took two days to get the new ones. I'm happy now, no random restarting anymore altough the computer seems to be running a bit slower with the replacements.

              Hope this helps.

                Thanks for your reply, I'm still trying to narrow down my crash issue.

                I've been using the same Kingston 16GB as you I believe, I switched back to 8GB (2GB x 4 modules)-- removed all of the 4GBx4 modules for now and I'll see if it recurs. The problem with my issue is it only happens every 1-2 months (spontaenous reboot).

                I'm not updating my thread until it hasn't crashed for 3-6 mos or so as it has been ridiculous (replacing mobo, cpu, psu, etc, still occurrs..)

                Has to be memory at this point is my guess.
