Heres the problem:
After reading the guide on this site on repairing windows, I decided to actually do it, because of several factors. I keep getting C++ runtime errors when I try to play some games, Cant play DVDs or use windows movie maker. And also, I installed an update which I cant get rid of, and it stuffed up my 5 in 1 card reader/writer.
So this is what happens, I reboot with my XP installation CD (which came with the computer) and it got as far as the "Installing Network" stage, then it stalls. I tried once again, and again. Now I was angry, I cleaned the CD, but came to no solution, it still stalled. Now something new happens.
Currently, this is what happens:
The computer starts up, shows the XP loading screen, and then says "restarting setup", it then displays a black screen and reboots itself.
I hope a good solution will come up for this problem, and helps other users with the same problem.
Thank you for any help.
