Hi folks!
This is my first post on this forum and I joined since I am particularly having problems with my mobo (MSI 785GM-E65).
Here's what happened...
A few days ago, I went out for a vacation (just 5 days) and I unplugged my PC from the wall outlet since no one will be left at home. I got back after 5 days and when I plugged it back, it was turning on but it was not POSTing. After a couple of times power cycling and pressing the reset button, it finally POSTed but I got a CMOS checksum errror. This board is relatively new, barely a year old and I always had it plugged in to the wall even if it is not in used. Well, except when I went out for vacation that is... so I was thinking, isn't it too early to get checksum errors? Absolutely no changes were done as it was working perfectly before I left for vacation and it was just left sitting on my room unplugged to the wall.
When it finally POSTed, I had difficulty navigating to the BIOS screen and even had difficulty loading defaults since it seems it locked up on the BIOS menu and then I have to restart again. BIOS voltages looks pretty normal to me by the way.
After a few tries, it finally booted to Windows. So, I used it the way I normally do but to my surprise, I keep getting BSOD and it was giving different errors (page fault, etc...) each every BSOD's. I had like 5 BSOD's in an hour so I went ahead ran Memtest and to my surprise, I got memory errors all of a sudden!
I have 2 4GB DIMMS (Kingston Value), so I removed the other one and then ran Memtest again... it checked out fine and with no errors for 3 passes... I removed it and plugged in the other one on the same DIMM slot (1)... it checked out fine as well and no errors for 3 passes... I plugged both of them again and re-ran Memtest and now, no errors for 3 passes!
By the way, I was still randomly getting the CMOS checksum error, so I had enough and went ahead replaced the CMOS battery. Boom, after replacing it, it didn't POST again but finally it did after a few painful tries. I'd say painful since I removed all of the components RAM, GPU, HDD, etc... (except CPU) and then reconnected them one by one and then I turn the system on to check if it beeps or something (and it did)... after finally reconnected everything, I initially got the CMOS checksum error but I went ahead loaded defaults and it finally booted back to Windows.
I rebooted and re-ran Memtest (checked out fine with no errors for 3 passes), also ran SeaTools (and all of my HDD's checked out fine with no errors as well).
Finally in Windows, and no BSOD's so far... I went ahead ran further tests and monitored temps and voltages...
> 3DMark Vantage = checked out fine
> AMD Overdrive = it locked up so I had to reboot and tried it again. It ran, but it stopped after 5 minutes or so since it had errors (I was unable to trace what it was since I can't find any logs for it)...
> Prime95 = Fatal errors found and it stopped the tests. Error seem to happen randomly on either of the 3 cores (I'm using an X3 720 BE - stock) but they don't happen all at the same time.
Voltages and temperatures were within range it looked normal while running Prime95... so now, I am losing my mind as to what could really be the problem...
I am suspecting the following... though it could be less likely to be CPU or RAM couldn't it?
- PSU
- Mobo (CPU to RAM interconnect or somewhere)
- CPU
- RAM???
Sorry it's like a poem, but I am hoping for some advise...
