Overclocked system hickups?

[gphang]

I have a Duron 700@950 running on a KT7+Raid motherboard. It runs at 950 very stable (even at 980&amp;990 with different fsb setting) but it seem like my computer will spontaneously reboot. I leave my computer running for like 18 hours a day and it will average a reboot once a day. It'll just reboot and not freeze or anything. Its ike someone pressing the reset button. Overheating is not a concern. CPU tem <45 under full load (overclocked) and case temp <35. Concerned that my system hickups due to overclocking i set it back to 700 and been running like this for last 3 days without a hickup.

Other info about system.
Cheap PC100 ram (but was running 100 fsb x 9.5 so that shouldnt be a concern right?)
Cheap S3 Trio3d 4meg AGP video card (I'm thinking this might be my culprit)
3Com Ethernet Card 3C905B
3cpm USR 56k modem (isa)

Any suggestions or help would be much appreciated.

check your memory timings... make them as slow as possible and work your way back to a your original setting.

also what os are you using?? i know win2k has an option to auto reboot on system failure.

My memory setting is set as cas3. 100 fsb as default. Can i get slower?

Where is this auto reboot on system failure option at? I'll look into that but it seems like my computer randomly picks a time to hickup.
