This is a new system abit kt7a via kt133, amd k7 1400 mhz, 256 mb pc150, gts geforce2 running winxp.

Here is all the stuff it was doing yesterday


1.the mouse "flutters" or stalls, the problem seems to come and go (with the sound card totally out and only a nic card in, I have tried every pci slot)
2. it reboots for no reason all all (even without the sc and with nothing big running like a game, when I came home today it was rebooting as I came in the door)
3. When the SC is in, the windows noise (first noise that windows makes like a welcome noise) is real terrible, all static BUT everything after that sounds perfect. (UT 3dmark all other sounds including other windows noises)
4. When I enabled all the four way interleave stuff it wont boot up at all. I have to go back to the bios and turn it back to default and/or clear the biose (I have had to do this like 5 times to get it to reboot, the problem persists) .This morining I felt that the video card feels warm (almost hot) to the touch (the fan on it (the vc card) IS spinning). The cpu was cool to the touch. (nothing is overclocked)
6. crashes almost every time at the same place when running 3dmark2000 (when the helicopter blows up)
7. I tried the other nvidia driver 12.9 and it did not help.
8.All of this stuff has been going on through all different bios settings, everything from the default settings (and just upping the cpu to 1400) to tweaked.
9. I am building another identical system at work, I brought home the 256k of kingston memory and replaced it with mine, the problem did not go away!
10. the only speed/multiplier setting that equals 1400 that will post is 12.5*107. the max that will post at 133 is 10.5 (1266)
11. I turned off my computer for an hour, took the side off (fong 300) and pointed a floor fan at it, just in case it was a heat prob. the problem is just as bad.
12. I have played several games of UT WITHOUT crashing. but with nothing running it still crashes. (like within 5 minutes of closing UT)and the funky mouse stutter flutter prob is still there.

(the mouse funky think does not show up in UT)

I am thinking it has to do with some kind of heat issue even though nothing is overclocked.

The case is 300w. I currently have the voltages set to default.

HERE ARE ALL THE THINGS I HAVE TRIED TODAY!

I have tried a lot more things, but still it won't work

1. flashed bios (to kt73r)(which supports 1400mhz)
2. ditched windowsxp and reformatted to WinME
3. Installed the 4n1 drivers, detonator, dirextX8

The mouse flutter problem is gone BUT...........

I STILL can't run the cpu by ANY multiplier times 133, even well below 1400 mhz
it just goes to a blank screen and I have to clear the cmos.

I am having to run it at 110*(various) for testing, even well below 1400 it crashes, however it will boot to windows just not run a 3d program (crashed immediatly or after a short time)

I have tried this with everything taken out except for the video Card (gts2 pro)but it still crashes.

Oh, this may be a tip off. I tried to install the AMD driver pack but it gave an error message that NO AMD DEVICE EXISTS!
(I took the fan off and checked the processor, silly I know but anyway iT says amd all over it and "a1400ams3c")

"also at this point I don't have all the default bios setting except for cpu speed"

First off... flash the bios back to ZT. ZT is probably the bios that very few have had problems with. Set the bios to fail safe or optimized defaults. Disable anything you don't use, like serial or USB ports.

Keep you ram timings at Cas3 and 8/10ns for now. Manually select the CPU settings...

10.5x = multiplier
133 = FSB

... and increase the voltage a tad (0.05V) to try to keep in more stable.

If possible -- try another power supply (350W plus preferably).

Try to follow Mark0999 instructions.

Just wanna add on...the PSU is not the issue here. You have enough power.

It is not just the quantity of power, but the quality. I'm not advancing the p/s as a likely culprit, although it is a possible one. Good luck.

OH MY GOSH.

after all that IT WAS THE MOTHERBOARD. I am 100% sure. I took the whole thing apart and used a differnt kt7a. It is fine/stable at 133*10.5 (1400) and probably higher.

Thanks a lot for all the suggestions, I learned a lot! I hope they warranty it, but I am just glad to what the problem was.
