And when I flash with phlash17 (only phlash17 not phlash16 or winphlash) pc shut down itself when process isnt done. Half of "flash memory block ..." pc shut down.

And I tried another things (phlash16 and winphlash) too but I hope thats enougf for your get it. I know I have a little mistake but I cant see. Please help me I flash my bios 15-20 times last 3 days.

Thank you so much ITS WORK GREAT. I changed uuid, guid and everything else really easy But I have a another question. I banned a server by console 3 week ago (dont ask why a virus which is downloaded from internet spamming the server by me) and trying to unban but nothings work. I dont know they banned what? (uuid, guid, mac adrees, system name, system serial etc etc...) I tried to format my computer 2 times and change hard disk serial system name mac adress ip adress such this things. And today I (Thanks for TTAV134 and anmg) change bios infos (uuid, guid, system serial) But Iam still banned. Which info can they ban me? What should I change more?

(more detail: There is a program installed client side for enter server. This program generates a Unique ID for each computer from somewhere(I try to find but cant) such as '0:0:436280697' (this is my ID) What should I do? How this program can recognize me? Which bios value that I have to change or another things to unrecognize?

Thanks for any ideas...

 

Thank for ideas. I am really gratefull. But my ip is change every ADSL resets. And I try manually change IP and try proxy change even change ADSL another mark and model. I went another city (another ISP) and try again. All result>failure. The server cant recognize me but program which is access to server, recognize me and give the same ID everytime and I cant access a banned ID.

Another ideas
