   Help please, Directx 9a SDK crashed win2k
  Recently I had downloded "DirectX 9.0a SDK Developer Runtime"from MSDN.com and I tried to install that on my computer. It gotinstalled properly and at the end of installation there was a message asking me to restart computer. But after rebooting,windows didnt work properly. Windows starts loading but at themiddle of this process an error happens. And a bunch of errormessages appear on screen and system reboots. And this happens over and over again. The error is very sever as far asI can say because error messages dont appear in GUI but in"text screen", like a DOS application. Back in the dark age ofDOS and WIN3.1 these kind of errors happened every day.But this is the first time I have seen sth like this in win2000.I had no choice but to format my hard drive and install win2000again. Now I want to know what was the reason for this error. I think it might be one of these:1 - The file that I have downloaded is corrupted due to errorsduring file transmision. This is unlikely because if that was the case the "compressed downloaded file" shouldnt have even unzipped.2 - I have not installed any of service packs for win2000. So maybe if I install them this problem will be solved.3 - There is a bug in "DirectX 9.0a SDK Developer Runtime"which causes this problem. And maybe this bug has been fixed in "Directx 9.0b".To take care of this issue I have to download one of these1 - "DirectX 9.0a SDK Developer Runtime" (again)2 - win2000 service pack3,43 - "DirectX 9.0b SDK Developer Runtime"But any of these downloads are huge files which takes me daysto download. So I cant afford a "try and error" approach to thisproblem ( I mean to download one file if it didnt fix the problemdownload another one) this is going to take way too long. Andafter all the problem might none of these it might be in the driver of my graphic card for example! So what do you think is the most likely reason for this problem.
