Can't boot up- runs for 10 seconds and restarts
Today I turned on my notebook (purchased from Dell, 5 months ago and running Vista) and the machine only runs for about 10 seconds and then restarts on its own and continues the cycle repetitively. I tried to get into safe mode, but it will not allow me to - the notebook restarts itself too quckly.
On a positive note, I am able to get into the 'boot' menu and 'diagnostic testing' which is illustrated on the top right hand corner of the screen. I entered the 'boot' section, and I inserted a windows XP cd (I only had an oem version of VISTA). I figured I would reformat one of the drives, or load a new copy onto a secondary partition I have, however, once in progress, the cd indicates it cannot find a hard drive and then prompts me to reboot - so much for that idea.
My last attempt was to run the diagnostic testing offered through dell and so I have, thinking the hard drive is the issue. Fortunately it is not and the test ran through all sectors (and the rest of the notebook for tests) and everything passed.
I do not download anything that would put me at risk for a virus. I check my daily websites and that's it.
Any help on what else I can do to test it? A friend suggested booting DOS from the cd-rom and seeing if I can locate the i386 (where oem VISTA is kept, supposedly?)
