Got a major problem. Installed a new motherboard/memory (ECS KM400 w/ 512mb DDR)for a friends PC. Moved all of his components over (1ghz Athlon, 40gb Western HD, Lite-on DVD burner, 32X CD-Rom, 64mb Kyro II video card, 56k modem and some crappy sound card). Here's the problem: Went to start up for the first time (was planning on reinstalling WinXP after making sure it would boot up) and the bios sees everything (processor, memory detects all the drives) and the WinXP splash screen comes up. When it acutally tries to start up windows I got an error message concerninglsasse.exe . Could never get past this. Tried boot up via CD-Rom and install WinXP. It would initialize and then as soon as it would get to the "ready to install" screen...it would shut off. Tried like 6 times, but it would not get past that. I have since found out that the lsasse.exe is some sort of worm/virus. I pulled out his HD and put it in my PC so I could format it (did a quick format) and tired to install XP again, but the same problem arises (suts down as soon as it gets to the "ready to install" screen. Anyone have any ideas as to why the PC dies whenever it tries to install or startup XP?? Also, I get no beep when I boot the PC up, don't know if that's helpful or not.
