I've just returned from a nice round the world trip to find the family PC has a whole world of issues. They are as follows:
1. .exe files no longer seem to work. Even the setup option on the Windows XP CD wont run for me - apparently "D:\SETUP.EXE is not a valid win32 application"
2. CD Audio files wont play for me. I can read the CD's no problem but when i go to play it, there is always an unexpected error - regardless of what i try to run it on (media player, Creative Zen mediasource, iTunes, Real). It should be noted that I CAN play MP3 CDs though.....
3. My computer is running so slowly it's actually scary. Even this post is taking ages to appear on screen as i type it. The Internet itself seems to be okay (speed wise) but when i go to scroll down a page it gets very distorted
4. Sound seems to be extremely choppy. A video on youTube is a good example as it just seems to skip and jump audio every two seconds or so - sounds like a scratched CD or something. Even when i start Windows and the opening chime plays, it sounds really choppy.
I should point out that it's a brand new DVD-RL drive that i put in but apparently the sound issues were there before i did so. Also, i personally cant see how they would affect .exe files with such a message (which is my main concern). I have all of the latest Windows Updates and have been keeping an eye on the Windows Task Manager but there is nothing unusual jumping out at me. And i dont know what the family have surf'd through the last few months. I'm totally stumped.
If anyone could help me with these issues, i would be extremely grateful. I can post any HJT logs or Panda scan logs if need be.
Many thanks in advance,
