I'm having trouble with my HTPC that just crapped up a few days ago without warning: my computer is randomly rebooting, for no apparent reason. I've tested just about everything short of the power supply, which is why I fear it might be that.
I've run memory tests, and everything seems fine. In the bios when looking at my voltages, everything looks fine (however software readings show 12V being low, but that sounds common).
An interesting thing to note is that after the machine crashes it fails to recognize the SSD. I have to power the whole machine down, then when it comes back up it sees the SSD just fine. Weird.
It probably isn't interesting, but every time the machine comes back the Intel raid service (Rapid Storage Technology) is busily verifying my raid. It seems unlikely that this process is causing the issue in the first place, but is that somehow possible?
Is there anything else I can check? I'm really hoping I can avoid replacing this power supply since it's such a hassle.
My first Rosewill power supply that died started randomly rebooting the computer. Replaced it was a good power supply and all was fine. Power supplies are pretty highly failure prone and any weird issues I have, I usually start with the wall socket and start working towards the keyboard, eliminating potential problem parts.
^ This. Borrow a friend's working PSU and see if it makes a difference. Heck, go to Best Buy and pick one up, their return policy is that they must take it back within the first 14 days (or 30, not sure if the 14 day thing has gone into effect yet) if it doesn't solve your problem and issue a full refund.
Got a new power supply and swapped it out. I tried doing a prime95 stress test in safemode. After about an hour, it crashed again . I went into the bios and looked at my temps, CPU was around 63 and PCH was 73. I think that seems reasonable, but I am not positive. I opened up my case and am now just sitting in the bios, and my PCH has climbed back up to 73C. Since it is passively cooled, then it must mean the air in there is very stagnant, perhaps I need to get more fans in there and get cables tied up as much as possible.
I tied up some cables to see if I could improve airflow. I don't think it did much good, the ceton card forms a nice wall in my case, and all of the case fans are on one side, so it would be understandable that some areas might be too warm (where the south bridge is, for instance). I did move the ceton card though, the pciex1 slots are literally on top if the south bridge, so I sacrificed e pciex16 slot to it, we'll see how that goes.
I'm a bit disappointed that I don't have many cooli g options in this case with the ceton card, the only thing that I can think to do is try a slot fan, but these are never good quality nor silent (and I want a quiet htpc).
I pit om more fans, and the computer is running cooler now, unfortunately my problems persist. I'm unsure what to do at this point. It seems like I've tried just about everything short of formatting and re-installing windows.
