PLEASE SUPPLY RELEVANT INFORMATION:
Operating System Version:Win XP Pro
Problem Application Name & Version:
Problem Hardware Make & Model: Foxconn 755A01-6EKRS motherboard / AMD 64 3400 CPU
Error Messages: PC reboots!



I know this kind of problem is a bit difficult to tackle as it could be a number of things, but I'll post as much info as I can - any suggestions would be very much appreciated:

I recently bought a pre-assembled motherboard/CPU package (as listed above), to put into my existing system (which functioned perfectly). Before logging off for the last time before the swap, I changed the IDE controllers to the standard windows drivers. I installed the new motherboard and reattached everything.

The PC booted just fine into my existing windows setup and I installed drivers I got from the Foxconn website (as the company had forgotten to send me the driver CD).

Mainly it works fine, but occasionally it just reboots for no reason at all:

The most common time I find it reboots is either when opening an application that jumps to a full screen display, or within a game that is quite graphics heavy. It has also happened when playing music in Windows Media player.

After each reboot, I get the "windows has recovered from a serious error" message but it gives no indication of the piece of hardware/driver that caused it.

What I'm really after (I know people can't be miracle workers on such a broad issue) is whether it sounds like the motherboard/CPU is at fault (i.e. I can send it back to them as faulty) or whether it sounds like something in my existing setup is clashing with the (perfectly good) motherboard, or if a driver needs updating. The thing is, my old setup never once crashed on me so I know nothing was faulty that I've plugged into this motherboard.

I checked the BIOS and the CPU temperature is a nicely cool 39C, so it's not a temperature problem.

It's really frustrating because it DOES work (I'm using it right now) and sometimes for hours at a time. Then I could innocently go to start a game, or be listening to some music and it will reboot on me.

Any advice at all would be appreciated Smiley

If the new CPU is at much greater speed than the old processor your PSU may not be able to handle it.
What is the watts of your PSU?

Hi there

THanks for your reply! The PSU is 650W and the old CPU was an AMD Athlon XP2000 so I don't think it's the PSU

thanks

I think it's either the motherboard (drivers maybe?) or the videocard, or something related to the two. I am trying to navigate through the foxconn site, but hell is that a slow site. 5 minutes per page isn't going to be helpful.

So you tell me what videocard you have, if it is onboard. Same for the audio, please.

Hi Jee

I have a fairly old video card - it's a powered by Radeon one made by Crucial - equiv to Radeon 8500. It always worked fine on the old motherboard/CPU combo. I can try updating the catalyst drivers for it, but I don't understand how it was fine before and now it's not with the new motherboard.

As for sound, it's onboard sound with that motherboard and I installed the drivers from http://www.foxconnchannel.com/

This is the direct page to my motherboard on their site:

http://www.foxconnchannel.com/productsDownload_motherboard.cfm?pMotherboard=755A01-6EKRS%3Cbr%3EAlso%20known%20as%20K8S755A-FRSG%3Cbr%3EAlso%20known%20as%20K8S755A-6EKRS

Maybe I should try and put my old soundblaster card in and see if it's ok when not using the onboard sound? How do I ensure that the onboard sound is disabled when I put my old card in?

Thanks
Michael.

You'd have to go into the motherboard BIOS at startup and disable the SiS AC97 Audio. (see page 47/48 of your manual).
While you're at it, check what the settings are for your AGP card. More specifically the AGP Aperture Size and the data rate.
