Hang on boot

I have a computer that hangs on boot.  I sometimes do a hard re-boot and it seems to come up fine, although with a long blank screen pause.

Any suggestions for how to start troubleshooting?

Could be just about anything.

Hardware or software ...

I'd download the UBCD https://www.ultimatebootcd.com/download.html  Make the CD and boot from it and run the appropriate utils - Memtest to test the memory and the appropriate util (most manufacturer's utils are on the UBCD) to test your hard disk.  That'll eliminate two possible faults.

Also open box and check your system for dust and poorly connected cables.

Consider removing hard disk from computer and placing in USB caddy and attaching to another machine.  There you can run a good anti-virus application over the hard disk.  Could well be malware on this disk causing a long boot.

Also consider running a Windows 7 Startup repair that is for issues like this.

I seen this issue with the a laptop this sits on the blinking cursor even before the post is released to the Operating system.  The blinking cursor would stay on for almost two minutes before I saw the windows start logo (in other words there was a big delay before the boot up process finds the proper boot up device). This occurred even when the hard drive was the first boot device, and the bios was setup for a fast boot.  Often this occurs when there is a potential hardware failure as mentioned by dburton. If the computer has a diagnonstics partition on the hard drive or as part of the bios as Dell has, boot to the diagnostics and run the tests on your computer to verify that the hardware is working the way it is supposed to.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

1. Unplug all your unnecessary USB, PCI, secondary hard disks devices...
2. Unplug your Ethernet cable (in order to be aware from Internet )
3. Start your PC in safe mode (by pressing F8 on boot)
4. Once you're on your desktop press WIN button + R in your keyboard and type msconfig
5. In the Services tab, tick on "Hide all Microsoft services" and then click on DISABLE ALL
6. In the boot (startup) tab, click on "disable all" and then perform a system reboot normally....
