New here folks, so go easy

!!
Have a problem.. Have an HP running XP Pro, and was trying a restore a 'few times' because it would'nt restore back and lost power during the attempt.. Ended up getting a BSOD 'bad check sum/doesn't match computed sum error'. So I did a XP repair install.. All looked like it was going well, loaded everything/key ect. and when it goes to reboot at the end of the repair I get the XP loading bar/logo and it loads 'just' past where I got the blue screen, but then stops DEAD (just before the welcome I think) and all I have is a black screen with the pointer.. I went into the repair console and did a bootfix and such, but same problem.. Anybody have an idea on a sollution.. I can do a clean install, as there'snot much data to save, and what is there is on CD, but would like to just complete the repair if possible..
Thanks.......Rob...
