Hello Hexus!
I have two strange problems and I suspect (or at least hope) that they are related.
Problem 1) Graphical Anomalies
A few days ago, the game 'Two Worlds' hanged on the menu screen and required a holding down of the power button to switch off the system. Upon rebooting, everything seemed fine, till I loaded up the game again, at which point the screen became littered with little green dots and the system hung.
I duly restarted it again. I was quite shocked to see now that on the 'splash' screen, were strange white lines (thin horizontal ones and thick vertical blocks) and various coloured dots and these persisted throughout the boot process til finally at the Windows 7 boot up screen (where you have the little pulsated windows icon, just before the screen where you put in your password), the system hung and bsod'd me!
After a few restarts, the problem seems to go away and stays away unless I load up that game again (I've tried a few others that are just as, if not more, graphically intensive and they create no problem.) I haven't tried reinstalling the game yet (disks are at home, which is not where I am living right now ) but it seems strange that the problem persists even upon a restart...
Problem 2)Blurry/smeared text
I first noticed it on the little information box that comes up when you run 'dxdiag.exe'; the text on the 'display', 'sound' etc. tabs all seemed slightly skew and blurry. I've now noticed that whenever I hover my mouse over anything that usually brings up a little information text box (like the icons along the start bar and on the start menu, on the control bar) or any pop notifications from icons in the action bar (bottom right hand corner) the text is blurred and completely unreadable. It appears in some persistant places (like the tabs on the dxdiag box, and some text on the bottom bar of internet explorer.) In fact, I've just noticed that although drop down menus (File, Edit, Tools etc) at first seem fine, if I run my mouse across the various options, the text completely skews and blurs. Further to that, in Word 2007, in the little box that says what text you are using, the name of the text is blurred yet when you bring up the little drop down menu, the text all appears as normal.
I haven't run many diagnostic tools at this stage. I'm in the process of running a virus scan, just in case. A couple of our computers at work have been laid out by viruses recently. My personal computer has had no contact with the infected machines, but it has me paranoid nonetheless...
Let me know what further information you require. I will add in at the bottom any other places where I encounter text problems or graphical anomalies, in the hope that it helps.
