|I'd be grateful for some expert opinions on the likely cause of a frequent computer freezing problem. The symptoms are as follows: |
Initially the graphics card was integrated with the motherboard and when the PC froze the screen display just went to diagonal lines in the predominant colour of what had been showing on screen against a white background. A separate card was added and all seemed fine for a while, but then it began to freeze again, but now the screen display remains intact but frozen when this happens.
Although there has been at least one occasion when I've experienced freezing after the mchine has been running well for several hours, it usually tends to happen at the start of a session.
For example over two days recently it froze a dozen times, i.e. three times early in each session I was using it, after which it behaved impeccably for hours. The next day it was fine in each of the three sessions it was on with no freezes at all that day, but not the next.
On days when it is subject to freezing it can freeze when typing too fast in Outlook - but not in Notepad - or when trying to move Internet Explorer windows about. But it can also freeze when there is no interaction with it at all, e.g. when downloading a file from a website.
The blue hard disk activity light is usually either out or permanently on (not flickering) when the system freezes.
A slow redrawing of the screen is also sometimes noticeable with the mouse pointer not changing from a hand to an arrow very quickly and sometimes not being able to bring windows to the front by clicking in them.
In addition, and this may be unrelated, information can be read from my DVD writer but not written to it. Since this applies to both Nero and Roxio, it doesn't seem to be a software problem, at least not one internal to them.
It's an AMD dual core processer, M2N68-AM motherboard.
Thanks in advance for any help.
