Computer shuts down randomly

[pclstyle]

I swapped out my k8n se deluxe for a K8N-E DELUXE NF3, took off the cpu sink and all that and put everything back together. powered on fine, except now i have random shut downs occurring. i'll be in the middle of something, and everything will just die as if i had pulled the plug. I can power it back on immediately, but it's frustrating not knowing exactly what's going on. i'm using a 470w psu, and i'm pretty sure it's function fine. the only thing i noticed is that the fan speed in bios for the psu is in the red, but not significantly so. is that cause enough for the shutting down?

on booting, i don't have any error messages or whatever popping up, nothing about cpu temp or whatever, i'm not really sure what i should check/do. happened really infrequently at first, but now it's like 2-3 times per day. any ideas?

Could be a driver issue. Even though the drivers should have been the same. I'd first get a driver cleanup program and delete all the old ones out as best you can, after you uninstall the nForce drivers in the Add/remove programs list. Then install the newest nForce drivers as well as the latest and greatest BIOS revision for the board. After that, if your still having this problem, its probably a hardware error.

You can do a system wipe and restore as well, I am lazy and do this sometimes instead of working issues out because I like to. But that is me. But if you did that and it still occured, that would pretty much guarentee a hardware issue. Either the board, the memory, CPU or PSU. You would need to narrow it down but since everything was working fine before, I'd vote that its a bad motherboard. But I'd do the things I mentioned first, then a wipe and reload of Windows if that still didnt work. Then as a last resort, RMA the board.

Sounds like the PSU is overloaded, and possibly overheating. I would replace it, is it a generic?

I have seen something similar to this twice.

This first time, after much frustration, I discovered that my network card was causing it. It was because the card was installed in a PCI slot it did not like. I installed the card in a different slot and that fixed the issue. That was on an older motherboard though, and I hear PCI slots are not picky anymore.

The second time, it started to happen on a one year old system. That instance was indeed caused by a motherboard that went bad.

Thanks for reminding me. One computer I build for a friend had a similar issue. We found out that it was the NIC card built into the motherboard. We went out and bought an external PCI NIC card which fixed the problem. It was a bad motherboard, but only the NIC card on it was bad. If you have one laying around you can test this and see what happens. Otherwise I would RMA it. After doing what I previously suggested of course.

Especially since you could probably be running older nForce drivers on a newer board.
