I just recently chnaged my CMOS battery and now the computer will not get past the POST process. On two occasions after chnaging the battery, I was able to boot into safe mode. I tried doing a system restore but that failed. On loading, the load bar show that it is staring to load, but then it stops and does not load the OS. The only way to get out of this is by turning the machine off. I am running Windows XP. Please help!!!!
