I have built the above system about 1 month ago.

I have an issue where I can't keep the system up for more than 2 days at a time. I have begun running some tests with the Ultimate Boot CD diag CD. I run a CPU test, it just hangs the system. I run memtest86, it hangs the system. How do I go about determining what is causing this instability? It's pretty tough to enjoy my HTPC when it can't even stay running.

Other symptoms include:

Waking up in the morning to a blank screen. It seems like it's in a suspended mode, but I try any and all keyboard combos and I get nothing.

I can be in the middle of running MP and it just reboots with no indication as to why.


I don't see any heat issues so I'm pretty perplexed at this point...

Any suggestions would be most helpful and appreciated!

EDIT: I'm following this thread at the AnandTech site: http://forums.anandtech.com/messageview.aspx?catid=29&threadid=1908388&STARTPAGE=9&enterthread=y

i would check all fans and heat sinks in the system (northbridge).

next i would try to replace the powersupply.
i had that quite often, that i.e. the +5 Volltage breaks done -> result reboot

it can work for days, or minutes......

if the problem is still there, i would try to replace the RAM.

if a new powersupply and RAM doenst work, then it could be the mainboard (VIA chipset?) or the CPU.

If it hangs under Hiren's, then i don't think the chipset of the mobo could be at cause (Via has somewhat buggy drivers under windows, but Dos should be ok)

So, check the thermal paste on the CPU, the PSU and try removing one of the RAM chips and see what happens...

In my case I have been getting progressively worse hangs on restoring from standby. This system has been running solidly with no such issues on 0.2.0.3 for quite some time. I had a couple of crashes (reboot while playing TV) 1 week ago , and since then it has been very unstable on restore from standby.

I've seen some situations where similar crashes/reboot scenarios have caused rewriting/corruption of BIOS settings. Given the fact that restore from standby is very BIOS specific, I thought I'd reset my BIOS settings back to factory default, and then reset any other settings I had customised back to how I had them.

Since doing this (and nothing else), I've not had a single problem running for 2 days now (probably 20-30 restores from standby). Prior to the reset I would get a hang on restore 2 out of 3 times before.

It's not very scientific, and may be a bit of a placebo, but it might be worth a try.

very good idea!!!

I've set my BIOS settings to the defaults.

I ran like that for a few days and it still hung.

I have applied the latest beta BIOS 0402 and we will see how that treats me

Just wanted to post an update...

I was talking on IRC with the members and after speaking with Commodore 64, he suggested I up the DDR voltage. Default for my memory is 1.9V. The max my M2N-E supports at the moment is 1.95V

I was able to run a memtest86+ for 3 minutes max BEFORE this change and my system would reboot.

AFTER this change, I was able to run the same memtest86+ for 1.5 hours with 3 passed tests and 0 failed!

I sure hope this was the magic bullet!

THANKS Commy64

CBM64 doesn't speak much nowadays but when he speaks, he Speaks

I wanted to let anyone following this thread that changing the DDR2 voltage from 1.90V to 1.95V has pretty much solved my HTPC reboot and "blank black screen" issues. I'd say my stability has gone from 50% to about 98.9%

Again, thanks Commy64!
