    I have been trying to resolve this issue for 2 days on and off now. Don't seem to be getting anywhere

    AMD x2 5050e
    Gigabyte GA-MA74GM-S2H
    2x 1GB OCZ PC6400 Platinum ram

    Vista ultimate 32bit

    Basically what happens is the computer screen goes blank, no BSOD, no beeps nothing just blank. Then restarts (although before bios update it didn't even restart it would need powering off and on again)

    So I have the latest bios, I have tried re-installing windows. I have ran memtest a few times.

    I wanted to run memtest on a single stick of ram at a time but due to the cpu cooler position its not possible for me to remove ram without taking it off and I have no thermal paste with me at uni so can't put it back on :sigh:

    Now the OCZ ram I have runs at 2v, so I have set this at the bios although I have tried it at 1.8 and 1.9
    Still same problem

    It really is random though, can be a few seconds after boot or 30-40 mins into the windows session where I can load the cpu playing hd movies, copying GB's over the network and its fine.

    Anyone got any idea's on what I can test now besides single bits of ram

    Firstly I would turn off the automatic restart function, so atleast you then get to see some sort of error screen (bsod) which should give you some sort of inclination as to whats going on.

    Right click computer in the start menu, left click properties, goto advanced system settings, startup and recovery settings, then untick automatically restart.

    now instead of resetting you should get an error message, if you do please post it here so we can give you a rough idea of what might be causing you the issues.

    have you overclocked the cpu, fsb or memory at all ?

    Should have stated, I have already done that. Made no difference at all.

    Everything is running stock speeds at moment. I managed to get 1 stick of ram out. Did memtest came up clean, so far 20 mins and no crash but still going to give it some time

    May be trivial, but ensure the heatsink is on and clamped properly.

    Just tested RAM I know works 100% ok (although the same brand etc)

    Same problem.

    It's not running hot though so guessing its fitted right. It can't move at all

    I have had problems with boot loaders in the past. Random restarts and such. Is your copy of Vista pirated?

    Have you checked the temp of all components?

    Are you using the integrated graphics or another card?

    Have you checked the chipset temps? I've been having a similar problem, but only while gaming, and it turned out to be my GPU overheating the southbridge. Once I cranked up the GPU fan speed to keep the GPU temp down, the southbridge stayed cool enough and no more crashes. Just a thought.

    It sounds like you've narrowed it down to the motherboard or CPU. I would imagine its a motherboard problem. Replace the board if you can.

    Usually spontaneous reboots can be attributed to faulty or underdimensioned PSUs. If you haven't already been able to rule out the PSU as the culprit then you should direct your attention to that particular component.

    Regarding temps...the chipset and southbridge are both passive cooled but don't get hot enough to warrant cooling.

    Yea I have a feeling its the motherboard, might teach me for buying second hand off ebay

    Already tried a different psu as well.

    I found a 'activity' which makes it crash everytime.
    Load up girder (http://www.promixis.com/) and when I try and load one of the usb plugin's for USB-UIRT it crashes every single time. With and without the device connected to the system.

    Well I can't seem to do anything in windows now, it crashes within a min or two now.
    But if I just leave it from boot it will run quite happily for some time ??

    Also tried uninstalling video drivers and not using any (for now) to see if this resolved the problem after it was mentioned on various posts around the internet about vista randomlly restarting, didn't change anything

    Well installed vista again (different unmodified disk) that dosen't contain SP1.
    Installed drivers

    No crash after 13 hours of running!

    So guess the hardware should be fine? but more a problem with vista

    Was it a hacked/cracked/patched Vista DVD? Seems strange if SP1 causes spontaneous reboots when Vista pre-SP1 is fine.

    Its a modified copy of my original which includes SP1 because I got bored of re-installing sp1 every time I formatted. I have installed it a few times on my previous file server and worked 100% fine every time.
