    Hi all.

    My computer, a reburbished PC from Acer Direct, keeps spontaneously restarting for no apparent reason. Going to phone them up tomorrow but was wandering if anyone had any ideas why it's happening?

    I wondered if it was the power. Thanks for the input.

    Hey guys getting BSOD's which seem to caused by impending memory failure. Ran quick diagnostic with windows diag tool, and got memory error message.What's the best way to isolate the failing module? Have 4 gbs of mem installed. Is it possible to test them individually using, say an app like memtest86, or would I have to rotate them in their slots to find the bad module?

    I'd test them in two pairs, whichever pair fails then test those two individually. Also check in your bios that they're being run at the correct speed. If it's a non gaming PC like a HTPC, consider unclocking them to prolong their life.

    I didn't change any settings in the BIOS as regards speed and voltage so that should be ok. Will test 'em in pairs ,see what turns up. Cheers :)

    seems a good thread for this becaue I'm not quite sure what it could be. Pc was working fine last night tried booting up this moring and while it turns on there's no image to the screen after the press delete to enter bios setup bit you get at the beginning. There's no beeps from the motherboard to help diagnose what the issue is. So any ideas where I should start looking?

    So you can see it post the bios and then nothing at all?

    yep see press delete for setup, press tab for post message. If i try pressing either button nothing happens and I still get a black screen afterwards. Having a feel of the case suggests there's hard drive activity but the light at the front says there's not.

    Oh, that's not good. Gut reaction is that the motherboard has popped a capacitor or warped through getting warm over long periods of time and lost some connections, especially if it's fairly old.

    Easiest way to check is looking at the board itself for either.

    well I've taken the motherboard out of the case and I've looked all over the board and I can't see any obvious signs that any of the capacitors have popped and the board doesn't appear to of warped either.

    Sounds like that bizarre problem I had with a new build the other day, I left it powered and it came on after 10 or so minutes, proper weird one.

    Aye just leave it for a while, i've had issues like that where i've come back after half an hour and it has decided to magically do something.

    Speak the truth hussy!

    Keep an eye it though, wouldn't want your house to burn down or anything.

    You could also try a motherboard CMOS reset.

    tried a cmos rest, no good. when I do a cmos reset it doesn't boot up and a screen comes up asking me to enter the bios to set the system clock and I'm not even getting that far.

    I've got a feeling there's not a lot you can do for it. Could be wrong, but you might need a replacement board. How old is it?

    If you can get hold of another PSU try that to eliminate it as a possibility.

    I had problems that were reporting as a motherboard fault, it eventually turned out to be the CPU power rail from the PSU.

    good question I bought it second hand off of ebay a couple of years back now I think, the board itself is an asus p5n-d which from a quick google was reviewed around june 2008.

    Yeah, asus aren't known for longevity tbh, so time for a new board imo. Gigabyte Z68X-UD3-B3 recommended.

    Yeah. It's slightly cheaper from Novatech.

    nm, they've sold out. Might be better to look for the revised version.
