"As a Senior Member you should be familiar with the fact that you need to provide precise details about your troubles if you want precise help. You have been a bit vague."
Yes, I do know that I left out some details, and that was to keep the post lenght short. If you make a post too long and cerebral, the majority of the readers will not read it!
"Let's see, your board seems to be restarting I think."
Yes
"Apparently it does this when you try to run SiSandra 2002 pro and 3dmark2001 SE."
Yes, along with other randow restarts (unexplained).
"What else do you have running?"
Norton Personal Firewall and Antivirus. Tried leaving them on and off, but the results are the same.
"What are the temps you refer to when you say they are fine?"
My definition of fine temps are under 45 degrees celsius, but the cpu never goes above 38, and stays around 30.
"What the heck does "replaced in a matter of days with a WD1200JB" mean?"
It means that in a few days, Friday the 10th or so, that new hard drive will be here, and installed into the system. It is impertinent information, just wanted to throw it in if someone thought the hard drive was bad.
"Did this start on or about this same time?"
HD not changed. Started around the time I changed some ram, but the problem is still there when I put the old stick back in.
"You see how we are guessing here??"
Yes.
"You say that you can no longer get 140 FSB. OK, how long have you been running it at that speed?"
Ran at 140fsb for weeks.
"What are/have been your temps?"
Right around 30 degrees. To be precise, it is 30 right now.
"Did you unlock your CPU? If so, how?"
Certainly not.
"And then the clincher: " I have however flashed the BIOS, so that may have messed something up, but what?" Uh, well, when did you do that? Could that have happened on or about the same time as the other problems?"
The flashing was an attempted fix. It is not the cause of the problem, but I considered it important.
"Have you considered flashing back?"
I have flashed to the saved bios before the flash, an older one, and a beta one, all with the same results.
"You might start by taking the suggestion to run a Scandisk/Defrag on your HDD first."
I run it two times a week at least, once this morning.
"Then try to run default settings w/no overclock and see what happens."
Yes everything set at defaults will complete 3DMark2001 SE.
"And above all, whether myself or anyone else can help, at least provide a bit more info; OK?"
I have created numerous posts with intricate details, and I find that what works best is to put out the situation and system specifications, and let people throw out ideas. I then follow the ideas that they give me to see what happens. It works for me when I have the problem, and when I'm helping someone with a problem.
