So i press F1, windows loading screen appears and then it reboots it self - back to start - this time with no info screen
If this is the Window logo with the "loading"
progress bar beneath it, you should stop the auto reboot on system error so you can tell us what the Blue Screen of Death (BSOD) says.
Report the "exact" STOP code string with its four parameters as well as any short error string and/or software module it might name.
Use the
<F8> function key during system startup to access the
Windows Advanced Options Menu. Tap the <F8> key once or twice per second as you startup the computer (or immediately after POST completes and
screen flashes black prior to displaying Windows XP logo with its processing bar display).
From the Windows Advanced Options menu, use the up/down arrow keys to select the "
Disable automatic restart on system failure" and hit <Enter>.
