After removing the Bestec ATX-250-12z Rev D2R (HP P/N: *5188-2622*)and replacing it with a Antec 350 the system boots. Unfortunately I have no working PS2 Keyboard or Mouse. Hangs at the Compaq screen for just over 20 seconds. I have changed the non working input devices for usb 2.0 units and now have mouse and keyboard and can boot with a Live Linux cd, but trying to boot winXP I am getting the could not start Ntoskrnl.exe file is missing or corrupt error. Looking about with my friend Google Search I find this website... [URL]http://www.computerhope.com/issues/ch000646.htm[/URL] Since I have no mouse or keyboard with USB in a windows boot could not use the WnXP CD boot to extract the file to system32... I have copied the file from a working windows, and then added it using Kdiskfree mounting the NTFS drive... But still show as a missing file, and I can not get into the Bios (no working keyboard), to determine if I could turn off the PS2 ports, to get passed the over voltage PS2 errors. Next step, will a PCI USB card with the keyboard and mouse work for entering Bios? Think Not... But am not certain... Am at a bit confused on the next Windows step to try, might there be a suggestion, I have already looked on ebay, and there are no similar motherboards for less than including shipping. Guess I will install a Mepis 8 Linux operating system, since it boots with the USB devices, after noting there is a over voltage problem with ports 7 & 8... I am not certain how long this system will last or if this is the first step in a total motherboard failure... I am going to switch hard drives and do a Linux installation and see if it will survive for a bit... this is a speedy Linux system, except for the initial logo screen hanging half a minute... If someone has a workable Windows suggestion, that way i still have original the WinXP hard drive for future boot attempts. JR
