PC Info: XPSP3 (an authentic copy) Dell 2.4GHz 2GB Ram I have to drives (recovery and main boot drives) I think I have a bug on my BIOS. Problem: The problem started after I was on Facebook (Had Win SP2 an authentic copy) and I reloaded the page and the page only displayed FB's loading vertical rectangles (in a way I had not seen before), across the top right of the page. After that I ran Norton 360 v.4 and didn't find any bugs. Eventually, I restarted my PC and I would hang before Windows had an opportunity to start. The only way to get the PC to start was to force the PC off and then unplug the power supply 3 times before I could eventually get windows (windows logo) to start. Some of the things I did: - I was able to eventually run Norton through safe mode and it didn't find any bugs. - I was able to update my PC to Win SP3 through the MS Update Site - I tried booting from CD drive and after many failed attempts I was able to reinstall Win SP3 on my boot drive. But, my PC continues to hang before windows starts, the same way it was doing before. Some of the errors I had, prior to Installing XP SP3: - Windows setup file nvrd32.sys could not be found setup failed. ( So I reinstalled GeForce 8600, my nVidia Chipset, and Theater 650 Pro which are all my nVidia drivers). - <windowsroot>\system32\hal.dll is corrupt or missing ( I searched for this file and it was on my PC) Any advice is greatly appreciated!!
