constant rebooting after restart

Have a very annoying problem. After a cold start or reboot, my computer goes into a constant reboot mode. I get the windows slider but then it never completes, gives me the blue screen and a msg (which I can't read since it just flashes and then disappears), then proceeds to try and reboot. Thought it may be a heat problem because if I leave it alone for a while it eventually comes back to a normal reboot though it gives me a msg that it can't find the AUTOCHECK program. I can boot into safe mode though. Checked all my capacitors, cleaned all dust out but problem still occurs. Leads me to believe it may be a software problem. Can you help please?

Try disabling Automatic restart. This will cause the system to halt at the infamous blue screen of death (BSOD) instead of continually rebooting, and hopefully display a useful error code and message. And it will allow you to look for errors in the Event Log. To change the recovery settings to disable Automatic restart:

1. Right-click My Computer and go to Properties > Advanced

2. Under Startup and Recovery, click Settings to open the Startup and Recovery settings menu

3. Under System Failure, uncheck the Automatically restart check box, then click OK as needed to exit out

4. Restart the computer and see what happens

At this point, when/if a fatal error occurs, it should not automatically reboot, but give you the BSOD. This does not fix the problem causing the fatal errors, but it does stop the endless reboot cycle and hopefully allow further troubleshooting.
