I had a had a winxp system, antec true430wt power sup, chainteck gforce fx 5700 , maxtor 120gb, sony dvd rw, zip250 floppy, 512mg crucial ballistix memory, abit nf7, athlonxp 2.2gb When I try to load or install winxp it goes through the post, then it formats and will try to load the sys files . THIS IS WHERE THE PROBLEM STARTS, I will get a message (windows cannot load the file_name press y to try again or b to skip file) after a few retrys it blue screens and I have to restart. This system has been working for at least 2 years then it suddenly started having random automatic reboots, then a little later looping reboots. So now I have purchased and installed a new motherboard and processor abit kv8, and athlon 64 3000+754pin. I was thinking that maybe I should build a new system just use the old perifs, and the old bird would be new. Wrong answer, the system loaded the first couple of times then it started to have bluescreens at startup in which a restart would fix. Then I got tired of the b,screens and reinstalled the os, now I am having the same problem the os will not install. I have done all that I can think of, swapped memory sticks, used different cd romdrives changed out the ribbon cables, removed all of the pci devices/usb. There is no problem with the graphics card or the power supply they are new and seems to be fine, also I have used two winxp disk just to make sure nothing was wrong with the disk. I am working on my A+ computer tech certificate, half way throught the book. Can anyone help, this problem has stumped me, I have put together at least 20 computers and have run into many problems that I have figured out on my own but this one is one for the pros.
