Blank screen

[Guest]

Hell
From some time I experience strange behaviour from my system... I leave my computer and sometimes when I came back there is only blank screen with my bacground picture no icons, no task bar, no start menu... And I can't do anything from keyboard, but if I presss power button and I answer yes that I would like to shutdown, he left me with a logon screen. Normally if I press shutdown button it shutdowns. Any ideas

You may be having hardware issues. Here are some generic hardware
troubleshooting steps:

1) open the computer and run it open, cleaning out all dust bunnies and
observing all fans (overheating will cause system freezing); 2) test
the RAM - I like Memtest86 from www.memtest86.com - let the test run
for an extended (like overnight) period of time - unless errors are
seen immediately; 3) test the hard drive with a diagnostic utility from
the mftr.; 4) the power supply may be going bad or be inadequate for
the devices you have in the system; 5) test the motherboard with
something like TuffTest from www.tufftest.com. Testing hardware
failures often involves swapping out suspected parts with known-good
parts. If you can't do the testing yourself and/or are uncomfortable
opening your computer, take the machine to a good local computer repair
shop (not a CompUSA or Best Buy type of store).
