I have a mainboard that is acting crazy by a long time, and at last :o I found money to replace it.
When I use the computer 24/7, the system crashes randomly after a variable amount of time. I never was able to find what is the real culprit, but every time the system crashes, running the memtest after a forced reboot I get a ton of errors. Sometimes I was able to notice a problem before a BSOD or a crash, and rebooting the machine to run memtest I get errors all the time.
The strangest thing is that shutting down the PC and waiting for about half hour, memtest gives no errors at all
Then the machine can run 24/7 again for some time (longest time without crashing was 7 days, but most of times a crash comes after 3-4 days; sometimes after less than 1 day ).
I changed RAM three times on this mainboard (a Gigabyte P35-DQ6); I also changed the PSU, but the problem is still here.
So I’m assuming that the culprit is a faulty mainboard.
My question is: if I get a new mainboard, can I assume that RAM are still good or I should get new RAM too? Can I be sure that RAM are not damaged even if I get errors every time that the machine crashes but errors are not more present after half hour??
Because of sometimes I need to leave the machine running 24/7, there are some things I should check before to buy a new mainboard? Any suggestions about a specific brand/model or any desktop board is good to run 24/7?
What about the PSU?
Is it possible that I damaged the RAMs or the mainboard itself running the machine 24/7 for a too long time?
Any suggestion is welcome
