i get the BSOD errors and i could not get to the desktop even when i use the last known good mode.anyways i could access to my desktop?

Have you tried Safe Mode itself?

yup i tried and also tried the safe mode with ms-dos and it's is still the same.

What is the make and model of the computer?

What Recovery disk(s) do you have?

What are the specfic errors?

msi via pm8m-v =>motherboard
intel p4 2.60c box pc-800-478 pin =>cpu
kingston 256/100 ddr ram
40gb maxtore hdd

i don have recovery disk as i just format my com and reinstall everything and once i install my wireless lan card driver and restart the come show mi the blue scree with the code message ***STOP:0x0000007E (0xC0000005,0x00001416,0xF96BCF0,0xF96BC3EC)

If the error coincided with the installation of the LAN card then remove it and see if it starts OK.

i remove le still could not get to the desktop.

You can try booting your XP CD into the Recovery Console:

Just another thing to try is boot your XP CD into the Recovery Console and try these two commands: FIXBOOT and FIXMBR.

If this fails there is not much left but a Clean Install.

thank the FIXMBR does helped.

Cool. So all is well now?
