my windows vista ultimate restarts randomly, often immediately after login.
just solved an earlier problem of just the cursor and a blank screen after login using a rootkit recovery tool, but then this new problem occurs, if this is relevant.
a blue screen sometimes appears before restart, but am unable to read it because it appears for less than a second.
when starting in safe mode, the computer hangs while loading crcdisk.sys. tried waiting for the system to finish, but it never happened.
again, if it is relevant, in the few times that it does not immediately restart, an error message concerning an lllegal write by ccapp.exe appears. (ccapp.exe is supposedly a norton antivirus program) could not disable or uninstall the norton program because of the restart problem.
short of reformatting my disks, could there be hope for my system?

Quick expert summary tied to the thread: a Safe Mode hang at crcdisk.sys usually points at Windows’ disk-block verification filter (registry/OS-file corruption, bad sectors, or a failing drive) rather than a random user program. Given ’s earlier rootkit cleanup and the reported ccApp/Norton crash, focus on non‑destructive recovery first: collect logs, check disk integrity, then test RAM and boot metadata before considering a reinstall. (learn.microsoft.com)

Start from Vista install / repair media (Repair your computer → System Recovery Options → Command Prompt) and run these in sequence: run Startup Repair, then check and repair the disk and system files:

chkdsk C: /f /r
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

If boot metadata looks suspect, run:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

These are standard Recovery‑Environment repairs for disk and system file corruption. (learn.microsoft.com)

If the above fails, test hardware: run your drive maker’s diagnostics (for example, SeaTools) to rule out physical HDD/SSD failure, and run a bootable memory tester (MemTest86 or Windows Memory Diagnostic) to rule out bad RAM—both can cause BSODs and unexplained restarts. If diagnostics show failures, replace the failing component before reinstalling. (seagate.com)

About the Norton/ccApp symptom: ccApp.exe is commonly part of Norton; if it’s causing crashes you’ll want to remove it with the official Norton Remove & Reinstall tool (use “Remove only” when appropriate). If Windows won’t stay up, export Event logs from the Recovery Command Prompt to a USB for later analysis (example: wevtutil epl System X:\System.evtx) or copy important user files with a Linux live USB before any destructive step. Use the above repair steps first; reinstall only as a last resort. (support.norton.com)

Final caution: back up user data before running offline repairs that rewrite disk structures, and run diagnostics in the order above (disk → system files → boot records → hardware → software removal) to preserve recoverable data whenever possible.

Hi and welcome to Daniweb,
Go to this windows site and follow instructions on how to access your event log. If you can repair from that info OK, if not, post back with details about the report and as much info about you old and new problem and info on your machine.

I haven't used Windows vista yet but your experience will be helpful for me in future.
