My monitor has been freezing frequently for the past few weeks, requiring a restart. I have tried all of the cures kindly suggested on this forum, but to no avail. In frustration, when it froze last night, I thumped the case..., instant cure! The same treatment worked again this morning. This suggests to me a loose contact inside the infernal machine, my question is; Is there anywhere obvious that I should look? faling this, what size hammer should I buy for future remedial treatment?
Ok,it was just the first part that made me think it was the monitor you were thumping,lol. You could check all the fans are working as a first step,then make sure all the connections are firmly in place.
I agree with Acolyte about the dangers of poking about inside a CRT monitor. But before you take a big hammer to it, I suggest that you try the monitor on a friend's computer to see whether it still gives problems. If it does, then you know that it is definitely at fault. If it doesn't, you should maybe check the connection of the monitor to the computer - see if there are any broken, bent or loose pins (I know that your success with whacking the monitor seems to exclude this, but the shock could just wiggle the connection a bit).
I think the problem may be your graphics card. It's either not sitting correctly in it's slot or it's on it's way out. It could also be that you need to update the grapics card drivers.
I would suggest that you update the drivers and see how that goes. If that doesn't cure the problem, disconnect your PC from the mains, open the case and gentle push the graphics card to make sure that it is sitting correctly in it's solt.
