Hi im new to these forums so please forgive me if i have done this wrong.

I really need some help with my comp as from what i can tell iv tried pretty much everything. I am now stuck for Ideas, as you can tell from the title my comp keeps crashing on me. At first it would freeze and then restart itself, othertimes it would just black out and restart itself. so i decided to reinstall windows, as i thought it might be a bad driver. So done that and guess what it still crashes, so that brings me to think that its a hardware problem. i have taken out my graphics card and swapped it with a different one, still crashes i tried taking a stick of ram out and swapping them around, still crashes. iv done endless tests and checks to see if a program would pick it up but no joy. I have a amd athlon 64 x2 dual core processor 4200+, 2GB DDR Ram 2 sticks of 1GB no they are not a matched pair and yes they are on different channels, DFI CFX3200 Mobo, 200BG Sata drive, ATI Radeon X1950 Crossfire Master Edition, a 550W power supply but have a dedicated power supply for my graphics card which is 250W. Please can someone help or even just suggest something. PLEASE!!!

This sounds like one of 2 things.

1) Bad power supply, could you monitor what it's outputting? or even better get an ATX PSU tester or swap the PSU for a little while.

2) Heat. What are the temps?

Please provide a little more info on those and hopefully someone will be able to help :-)

Hi thank you for replying. I personally dont think that its an overheating issue but i will look into it. The reason i dont think it is, is because hen i come home from work il switch the comp on for 5 mins and it will crash, then it reboots and will be ok for a while then all of a sudden itl just reboot again and so on and so forth. As for the psu it could be that as its only a 550w, but then saying that i do have a seperate power supply for my graphics card. as for testing i dont have any testing tools, i also dont have an alternative power supply that i can use ,but i do have a monitor program where i can monitor that the voltages are correct. Anyway my graphics card is at 54C and my CPU temp is in the attachements also there is a DXDIAG file there for those who understand it and can help. thanks again for any help in advance i appriciate it.

Hi Bego2k,

Those voltages and temps look good, unfortunately random restarts are an absolute pig to nail down.
So lets start with the memory, could you download the memtest from here and run the test on each module seperatly. Let the test run for 20 minutes Minimum on each one.
Once you've done that we'll move on and try other components.

ok thanks i will let you know when iv done it. prob be 2moz now as have to go to bed for work 2moz

Hi Radar

I done that memory test took over 3 hours!!!, but i thought feck it if im gunna do it might aswell do it properly. Anyway the results are bad, i had something like 13 errors on my memory. here are some screenshots of the results. by the way i didnt know how to run it on each module seperately and it run automatically so i just let it run it got test 8 when the errors started popping up is ther anything i can do???

Right, I think we've more than likely found what's causing the crashes, it just remains to find out which module is causing it, the only way I have managed to test the memory seperatly is to physically remove all the memory and only test with one module in the pc at a time.
Once you've isolated the module, try running the pc for a while with that one removed and let us know if that sops the crashes.
By the way only 8 errors is not that bad, i've had memory generate 5000 in 10 seconds.
