I am using pentium D system with 1.5 GB ram. My problem is Hard disk doesn't boot normally.
when i boot only Hard disk it doesn't boot I have freshly installed new Operating system od win xp with sp3. wheni insert any bootable cd of any OS it displays one message as usual "Press any key to continue" i will not press any key as this message diappear it automatically start booting my hard disk abd starts windows.
I dont know where the problem is? I have done some troubleshooting like clearing bios and taking out cmos battery and also reconnect hard disk cable ie, IDE cable and also power cable.
You question is not clear. It appears that you are unable to boot your machine, but it's not clear as to why are you putting the OS Cd into your Cd rom while booting your system. if your problem is as above, please try the below steps.
Please try removing your RAM modules and booting your machine. This could be a problem with your Memory module.
