I have an old dell c800 latitude it was originally formated with windows me and has since been reformated with xp. it now will start up and go straight to the screen where you can choose to run it in safe mode,last known config so on and so forth. no matter what option is chosen it will go to the black windows xp screen then to a blue screen that blinks so fast and restarts the computer and all i can gather is something about a stop error and a dump. help me please

A concise diagnostic addendum for the Dell Latitude C800 reported by : the system shows the XP splash briefly, then a fast-blinking blue screen and automatic restart. The first objective is to capture the exact STOP message (hex code and any driver/filename shown) because that single line usually points to either hardware (RAM, disk/controller) or software (driver, corrupted system files).

As noted, disable automatic restart on failure from the F8 advanced-boot menu so the blue-screen text stays visible. Recording the full top line (for example, STOP 0x0000007B indicates an inaccessible boot device; 0x00000050 or 0x0000000A suggest memory/page-fault issues) narrows the required tests and avoids guessing.

Booting from the Windows XP CD (as suggested) provides Recovery Console and Repair-Install options. Useful Recovery Console commands:

chkdsk /r
fixboot
fixmbr

Run chkdsk /r first to repair file-system errors and bad sectors. fixboot rewrites the boot sector; fixmbr repairs the master boot record (use with care—it can affect nonstandard partition tables). If system files are corrupted, an in-place Repair Install from the XP setup will refresh system files without wiping user data; always have backups before attempting repairs.

Parallel hardware checks are important: run memtest86+ from bootable media to verify RAM, run the HDD manufacturer’s diagnostics or try the drive in another machine, reseat or swap memory modules, and disconnect external devices. Because this C800 originally ran Windows ME, make sure XP is using the correct chipset/storage drivers—missing or wrong storage drivers commonly produce STOP 0x7B. If repairs fail and data is critical, clone the drive first and then proceed with a fresh XP install using Dell’s XP drivers.

Try to do a repair with your windows xp cd. Insert the cd, and boot up with the cd, and choose repair options.

When you first turn on the computer and get the start up screen of safe mode, safe mode w/networking and such. Choose the option for disable automatic restart on failure. This will leave the Blue Screen on so you can read it. Post what the blue screen error is so we can help you
