I'm running a Dell Inspiron 1370 laptop. I was running windows 7 until recently (I had started to experience a few problems; occasionally freeze but nothing traumatic). I recently upgraded to Windows 8 Pro (having backed up all my data on a separate desktop HD). Since installing Win 8 Pro, I have numerous crashes. I've tried a fresh re-install but problem persists.
Each crash is preceded with beeps (no particular pattern, 4 then 2 then 2 again etc). Then a blue screen flashes up for a second before a normal black screen with: a few lines of text before the final line "Operating system not found"
If I then reboot from the power-on I may get a few mins or even up to an hr (approx) before it crashes again:
I've tried the following:
1. Complete re-install (from Wind 8 pro disc) - several times - no avail
2. Crystal Disk software to check if hard drive is failing (all seems OK)
3. Kaspersky anti-virus scan inc root - nothing found
I'm worried I've got a more serious hidden root / boot virus but I'm no IT Jedi and hopeless out of my depth with how to fix
Any advice most gratefully received.
PS - Laptop has no files on hard drive which need saving
