hi folks
this is my first post here and i hope someone can help becasue im at a dead end with this problem. i recently did my first CPU upgrade, from a Slot1 PII 400 to a Slot1 PIII 700. I have an abit BH6 motherboard and the latest bios update. My problem is that, while the upgrade appeared successful, the machine recognizes the PIII 700 and there are no overheating problems (stable at around 38C/98F), Windows is now freezing within a few minutes after loading. This is after a cold boot. The desktop loads, everything appears normal, then after the machine warms up a bit, bam! lock up .. manual power down required .. . then on REboot i start experiencing worse problems .. the freezing happens before Win98 even gets a chance to load the desktop .. OR i get a boot failure before it even makes it to Windows .. at this point i'm screwed and can't get back into Windows until the machine cools down .. then i go thru the whole thing again .. normal boot .. . functional grace period of 5-15minutes .. then freeze .. then reboot loading failures .. it's very repeatable .. it seems to have something to do with temperature cause of the 'working for a while when cold / not working at all when warm' aspect of the problem .. but my bios tells me everything is fine . . so what could this be ?? bad CPU ?? im banging my head against a wall here . . .

I DONT KNOW HOW HELPFUL THIS IS BUT DID YOU TRY PUTTING YOUR ORIGINAL CPU BACK IN TO SEE IF THE PROBLEMS WERE CPU SPECIFIC OR MAYBE SOMETHING ELSE HAD HAPPENED WHEN UPGRADING AND WERE THERE ANY JUMPERS THAT NEEDED ADJUSTING AND OR VOLTAGE SETTINGS IN THE BIOS

Yep, and with the old CPU everything is 100% .. no probs .. ( and i really tried to force some several times/boots over w/ CPU overload etc just to make sure ..) .. so it's definatly a matter of having the PIII700 in .. the motherboard (abit bh6) has a great softmenu thing .. jumperless . . you just set the speed in there .. and the voltage is set at the PIII700 default .. 1.65 . . ( it was 2.0 with the PII400) .. so .. i don't know .. im stuck

Can you post some more detail about your system ? Did you set all the jumpers properly ? How about the memory ? What type of power supply do you have ? It could be a power supply issue.
