I would like to consult here this problems which I have been encountering lately.
Firstly, here's my PC specs:
board: ASUS P5PKL AM SE
cpu: Intel Core 2 Duo E7500 2.93ghz
ram: 2x2gb Kingston ddr2 800mhz (newly bought)
gpu: Radeon hd 6570 1gb ddr3 (newly bought)
psu: generic 600w (newly bought)
hdd: Seagate 1TB - os installed here (newly bought)
Seagate 2TB - (as backup for files)
I successfully installed windows 7, after that I installed first an anti virus, I was a previous ESET user, but upon looking at reviews I settled with Comodo Internet security. I then installed Tuneup Utilities 2012, then other various programs, firefox,Idm, my huge archive of old games.
I noticed that there would appear on the screen some distortions/blurry lines/runny lines from time to time. If I would try to reset the settings on the monitor itself, the lines would either get worse or simply reduce. I also tried to change the resolution in the AMD Catalyst control manager, and in the screen resolution setting, but it doesn't permanently solve my problem. I tried changing the refresh rate, but to no avail. What's also wierd is that these "lines/distortions" (sorry, don't know how to really classify them) only appear when I am on the desktop and doing simple tasks like browsing the web, playing windowed games like scrabble, pinball, etc. but whenever I would play full games like Stronghold, Red Alert 3, Need for Speed, etc. there seems to be no signs of the lines or distortions that are occurring. Sometimes these lines/distortions would occur on the borderlines of a window, sometimes on a specific side of the screen.. right now as I'm writing this there seems to be no distortions, (current setting is 60hz refresh rate) but when I change it to 75, the distortions would appear again. I hope you get what I am talking about..
What seems to be the problem? Hardware or software?
The video card has updated drivers, I tried doing system restores, I tried uninstalling the gpu driver and reinstalling again, removing the vga cord,
(I can't reformat again since my dvd drive's condition is getting worse, I was only lucky that my Windows 7 install was successful.)
Please try to help me! Thanks a lot!
