Hello
My name is George and i'm new to Gigabyte's Forum [but still a Gigabyte customer from the past 12 years!]. I have two problems with my mobo GA-EX58-UD4P (rev. 1.0) [F3]:
1) The first and
the crucial problem is an ERROR message that my BIOS starts to showing me up yesterday:
"WARNING: MAIN BIOS CHECKSUM ERROR..........". I have never flashed the BIOS of that mobo. If i'm thinking well, the main BIOS had version F3 (and the secondary too, for sure). Also, i have never ovreclocked my system. All settings are in stock values (optimized defaults) and my memory (RAM) jedec-standard XMP profile is set to #2 [7-7-7-20 timings @ 1333 MHz @ 1.5V]. I'm using my system about 2 years without any problem. And now, suddenly, without making anything to my pc (i don't install anything, i don't update any hardware, i don't connect any new devices), my mobo shows me that message...
Why? What's wrong? Why do you think that happened [erroneous/bad/faulty CMOS of my main BIOS for example?] ? What can i do to fix it?2)
The other problem is repeating only once per month, or two.
It is about system restarts [or better, BIOS POST restarts]... All i want to say is that sometimes, when i press the power switch,
my system gets "ON" for only 1.5 to 3 sec, then shuts down [gets "OFF"], and then restarts again without problem (passing the P.O.S.T. well and boots normally). In that period of 3 sec (maximum), my monitor doesn't showing anything of course... This restart is maybe looping sometimes for 2-3 times... Unexplained behavior.... When the system was new (about 2-3 weeks), nothing happened. But after that period, and again without doing anything or add/install/connect any new hardware, the system starts by alone periodically that behavior.
Again, why is that?? Have i a faulty mobo??To prevent any comments about memory errors, i want to say that when i setup my system [before 2 years] i'd run a
memtest86+ for about 16 hours, without any problem. Also, after starting the restart-behavior (problem 2) my system, i run again the memtest without getting any errors again...
Please help!
Thanx!
