New Athlon unstable

Last response: in Components

I just upgraded my system to an Athlon XP 1600+ in a MSI K7T266-Pro2 mobo. I added 256mb Crucial PC2100 in 1 stick. I have an original Asus geForce256 card, Adaptec scsi controller, 3com nic, 18gb scsi drive, dvd drive. I had addition equipment installed but removed it for debugging. My issues were that I could not run WCPUID as it would cause a blue screen. I could not install software from the DVD drive as I would get and error message about a failed writeback. I did not upgrade my PSU and I have an Antec 300w ATX that is not on the recommended list. I'm guessing this is my problem, just want a little input from others. My Ami Bios gives the following power readings:
+5v = 4.893-4.920
+12v = 11.923-11.984
-12v = 11.579-11.661
-5v = 4.926-4.976
+5v SB = 4.896-4.921
Vcore = 1.680-1.696
Vtt = 1.184-1.232
Vio = 3.296-3.312

After removing a TV tuner card, unplugging the USB ports, the floppy drive, and a CD-RW drive I can install from a CD again, but WCPUID still blue screens. I should note that I also have not updated to the latest BIOS yet due to unplugging my floppy. :-) I'll be doing that next. If I need to get a new PSU, what should I get? I hear a lot of people say Enermax. Anything else? How about under $50?

Thanks for any help!!

I'm offended if anything I've said offended you.

The biggest thing you forgot was the OS, and the drivers. Since drivers are a lower cost fix, that's where I'd start if I were you.

My system suxx if I use the 4n1 4.37's, regardless of the detonator 23.11's or the 21.83's. Across all platforms (NT and Me). I'm not sure what you'll have to do about the GF1.

I can see one problem that could be the cause of some of your problems.
You gave your Vcore = 1.680-1.696, the XP 1700+ needs a minimum of
1.75v. You might set it to specs and see if it helps.

Yeah what OldBear said, that vcore is mighty low, 1.75 is the right one.

The specs I listed are the "auto" settings put in place by the bios, after the latest updates. Upgrading my power supply to an Enermax 450w helped a little, but turning the primare ide channel in WindowsXP from dma2 to pio really made my system stable. Ran several 15min burn in tests with no problems. Hopefully it will continue to be stable after plugging in two more HDDs and TV card. Anyone know where I can find the specs for an Athlon XP 1600+ since AMD doesn't include them with the boxed proc and I can't find it on their site? I'd like to know what all the various settings in the bios should be at since I can't count on the auto settings being even remotely correct. (defaults are 100fsb and 1.68Vcore)
