my celeron d processor is now taking more time to boot it shows the intel board dispay and then taking lot of time to show windows LOGO and operate, so i tried to format by putting windows xp installation cd but its not booting from cd inspite of my bios set to boot from cd first priority please help.now on pressing delete key to enter bios only bios is dispayed no priority device is listed please helpSimilar happened to me a few years back - had to TAKE it in. It was a faulty power supply unit...Did you make any changes to the computer before this started happening?  Did you install a new program or a new piece of hardware?  Do you have anti-virus protection?  This problem COULD be hardware related or software related.  Without knowing more it's hard to say what the problem is.  now i found that my bios is set to boot from hard disc 1st priority and floppy second  third is DISABLED. i never did this.  i tried to get cd drive as 1st priority but it is not listed in bios but my combo drive takes up cd and plays how to get back cd drive as priority device. is my bios corrupted.my system boots only initial part is slow Quote from: kenlittin on January 18, 2008, 06:49:54 AM
