I'm about ready to toss this bloody thing out the window.

Ok here's the problems in order I discovered them.
The computer was freezing and unfreezing at random intervals, so I checked the cooling and put a better heatsink on the Duron CPU this seemed to fix the problem for a while

After a few months the same problem came back, I checked the heatsink and the temperature it was running at, and found it was normal, so I went and got some new ram, a newer video card and Network card, but still the problem persisted. I then took the computer totally apart to make sure there was nothing grounding it out. This is when I discovered the 3VSBSLT jumper pin were bent and the jumper cap was missing, so using a pair of needle nose pliers I straightened the pins and put a jumper cap in the default position.
After all this the problem sill remains, so I figure it might be the CPU so I go get a Tbird out of another working machine and replace the Duron with it To my surprise the Motherboard won't even POST with the thunderbird in it, I yank out all the memory and expansion cards and remove all the IDE connection, and double check the speaker, but with the Tbird installed heatsink and all the board is dead, I double check to make sure its in jumper free mode which it is, now extremely pissed figuring I've fried a Tbird processor, I decided to put the duron back in.. Power it up and low and behold I get the error codes I was expecting. So I take the Tbird CPU back to the computer I took it from, reinstall it and the machine boots flawlessly, so figuring what the heck I take a Tbird out of another computer, and put in in the A7V133 replacing the Duron, and again the Motherboard will not post.

The duron is a Socket A 700MHZ chip
The 2 Tbirds are 900MHZ Socket A Chips

The A7V133 motherboard is revision 1.04
A7V133 BIOS is 1007
I'm really at a loss here what to do.
The A7V133 with the Tbird in it does not Post, and no beep error messages
I wish I had a Port 80 PCI card..

Any Useful insight anyone?

are you running any usb devices? have you upgraded to the latest via 4in 1's? check www.usbman.com for fixes on the random lockups. as for the problems with the tbirds running in there, were you running the system at the correct fsb for these birds? ie are they 200 or 266 fsb?

Reset the cmos each time you change cpu`s... Also take out all the supporting cards and USB devices and get a different mouse and keyboard to try... ;) I had a problem with a mouse that would not allow some boards to boot but some others would... Strange stuff...? Gotta go throught the number so to speak...

No I am not running any USB devices on this computer, When trying to fix it I even removed the USB addon.
the FSB of these Tbird chips I believe are 200, and being on jumper free mode the computer should be able to figure this out. or aleast allow me into the BIOS to select the proper FSB, But with the Thunderbird Chip installed it would not Power On self test, which means I could not reach the BIOS.
yes one of the first things I did was put in the latest 4 in 1 drivers that I could get from www.viatech.com

The A7V133 Has never been overclocked.

Bartman39, I have tryed all that you have mentioned.. with no luck, but all the hardware works with the Duron installed. I tryed clearing the bios mutiple times, the bios did clear but it had noeffect on the problems

trying setting the fsb via jumper to 100 mhz....and see if this works...for some reason the board may not be able to recognize the cpu properly...I though this happen with durons and not tbirds..but it is worth a try..also may sure the cpu is sitting all way in the socket....seems stupid but if for any reason there is tilt the cpu may not be contacting the soket right..I noticed a 1200 tbird sat in the socket better than my athlon xp and took out and put it back and seem to sit better

Ok I have now Jumpered the System entirely, flashed the Bios up to 1008, but this freese and unfreese thing still happens, Could it be somthing to do with the network? every time somthing seems to access the computer via the network it seems to freese. but unfortunaly I'm no gru on networking..
any Ideas anyone?
