Absolutely no need to apologise
The message no cable connected tends to suggest that it is trying to boot from network
Go to setup normally F2 but on first post screen it will tell you to enter setup press
As soon as that see that message keep tapping the key.
That should get you into the BIOS setup.
On there you will find the boot priority that is the order in which it checks devices listed in the boot priority order.
One of those may well be boot from network
Make the order the DVD drive, then the hard drive.
If the network boot is the first boot priority change that, normally by pressing enter when that entry is highlighted.
Having done that exit and save changes which is normally F10
It will tell you that in ther BIOS, on the right of the screen
DO NOT make any other changes
Now reboot the computer and as soon as the first post screen appears keep tapping F8 key
You should now be in the screen advanced boot options
On there select
Disable restart on failure.
The second image on this link will show you the screen you are looking for
Now when it blue screens you will see the message and it will stay on the screen
Either type exacttly what you see having written it down
We do not need the introduction about
If this is the first time etc.
What we need is the error message eg
Page fault in non paged area or whatever it is
IRQL not less or equal
and the full set of numbers and letters on the stop error.
Now reboot and if it does blue screen get that message please for me and post it.
OR you may photograph it save it to the computer and attach it as an image
to do so on reply Use Full editor and attach following instructions.
If too large use your photo editing software or paint to reduce size.
On reboot go Windows button
right click the drive and click properties
On error checking click check now
Click to check the second entry, the first will already be checked - the second is scan for and attempt recovery of bad sectors
agree to run on restart and so so
After it has completed go windows button
windows logs on left pane
when that loads in the main window click once on the source heading, that wil sort them in order
look at the wininit entries
find the one that relates to chkdsk that you have just run
on the right click copy details as text and attach by right click and paste to your reply
Here is how to do this - chkdsk
and how to get the results
When you carried out the chkdsk go Windows button and in search type
when that appears above right click and click run as admin
at the cmd prompt
If it reports no violations you are done. If reports some errors could not be fixed run it again, up to three times.
and here is the guide to that
Now go windows button
right click computer
click on left pane device manager
Are there any warnings of a red or yellow mark on any devices.
If so expand the entry by clicking on the + sign and then open by clicking the entry
Post details of the warning on the device.
