First thank for analysing. Sir I don't blelieve that HDD sata 1 IS THE PROBLEM BECAUSE I have another pc with an hdd ata and I have made it to boot for 13s. THis pc has 2gbram but laptopo 4gb.The problem is showe when I installed iolo. This hdd has inteliwrite. If i uninstall its driver and make defrag and then reinstall driver can solve the problem. Perhaps iolo inteliwrite and dell intelli write are crashed. Also has any problem with drivers or any other proicess?
