Hi, I have a new MSI KT6V motherboard and a AMD Sempron 2600+ processor. I have installed the cpu onto the board but when it boots I can see the cpu fan start and then stop after a few seconds. I have tried a couple of different mb's and processors, cpu fans and get the same results. I have also tried different psu's and tried the board outside of the case. Has anyone expereinced this or have any ideas what could cause it? Thanks
I'm curious. You say that the CPU fan starts and stops after a few seconds, in other words it's the same effect as if you pushed the on switch and kept it pressed down? Maybe this is a really dumb idea but I would check the switch by unplugging it from the motherboard and using a screwdriver to boot the machine. Check out this tutorial for details on how to do that. If it's not that then I don't know what to suggest as you seem to have already tried everything I would do, i.e. switching as many components as possible. It seems the only thing you haven't tried switching is the RAM so that might be worth testing. If they don't work let me know and I'll see if I can come up with any more ideas.
I have tried booting it away from the case using a screwdriver and I got the same result. There are no beeps and although the fan powers off the motherboard seems to still have power.
:alarm: :alarm: :alarm: PANIC ALERT :alarm: :alarm: :alarm: That's not good news, what it might mean is that you have a computer that works fine (or used to) that simply has a dodgy fan connection. So what happens is that your computer runs fine and everything does what its meant to do except for the slight outpoint that your CPU is being roasted alive since the fan has gone on strike. As you've tried several different fans and CPU's is unlikely to be the fan itself but I wouldn't leave the power on at all if the fan is not turning otherwise you could end up losing the CPU. Did you test the CPU's in another computer after you had used them in the one you're testing? As for the fan itself I would suggest getting a fan that connects directly to the PSU rather than the motherboard as the problem could simply be with the connection. Then I would test the fan first to ensure it worked before I would let another CPU near that motherboard. I don't know if CPU fans that connect directly to the PSU are readily available but it's easy enough to re-wire it yourself if you know what you are doing. It's possible that I'm off the mark here but from your description that would be my first immediate suspicion.
well it could also be unrelated, because even when my computer is off the mobo still has power, with led's and the post code lcd on. I have no idea but I'm just saying that.
