I have a desktop PC (HP Pavilion Elite) that originally came with Windows Vista on it. (I now have Windows 8 Pro installed.) So my PC is at least 4 years old. Also I've noticed that the monitor isn't as clear as it once was. The black seems to be washed out. Twice this week my PC has given me problems. Earlier in the week I was working with it, when it suddenly stopped being able to access the Web via browser, email, etc. I rebooted and that seemed to help. Today while I was trying to print out a Word document it acted very strange. The instant I clicked on the Print button the monitor went blank, and nothing happened. I tried turning the monitor off and back on again, with no effect. I didn't see anything at all on the monitor. So I had to do a hard boot, something I hate to do unless necessary. In looked at disk management in the Computer Management applet, it indicates that the HD is "Healthy".
Now I think that if it were just the monitor failing, the print job would have continued, but nothing printed. So that leads me to think that it's the PC which is beginning to fail. I should also mention that I've checked the event viewer to see what it had to say, and there's nothing in it with regard to the cause of the problem. (The only thing in the event viewer was a message about a the PC being shutdown abruptly.)
My question to you is this, is it likely the PC which is failing, or could it be the monitor failing that somehow was able to prevent the print job from printing?
