Have searched the threads on this forum to no avail.
After computer has booted, and a few programs are running, occasionally a black screen appears and doesn't disappear.
Have never found any spyware, viruses, trojans, worms, malware, spyware and PC is scanned everyday with the below products.
Only way out of the black screen is to put the laptop into sleep mode (function and F4 key) then when it is woken back up everything functions again.
Have an IBM Thinkpad laptop only 1 year old and the black screen has occurred around 3 times over that year. Other than that, no problems whatsoever with it.
My question is: As I am a stupid n00b, can anybody offer any thoughts on:
1: What is causing the black screen to occur/appear?
2: What the black screen is or represents?
3: Remedies/solutions to avoid this happening?
Running the following:
Avast Professional 4.7.942
Zone Alarm Pro 7.0.337.000
Windows XP Service Pack 2
Spybot - S&D 1.4
(Note: all above are fully updated with latest patches/updates etc.)
Apologies if this question isn't relevant, thank you all so much for your help. Much appreciated.
