I seem to be having no end of problems with Windows 7.The sound keeps switching on and off.It would come for a day or so then switch off for about a week, then switch back on again for another day or so.
Whenever I try to play a video, whether from the hard drive or Cd or DVD, the picture shows but no voice.When I try to play music whether from the hard drive or a CD,I would hear the instruments but no voice. When I try to listen to my lectures, whether from the hard drive or a CD, there is no sound at all.
These are some of the remedial measures which I have tried but which have yielded no positive results.
(1) Upgrading the sound Drivers. A message would show up on the screen saying that the drivers were the latest and didn't need to be upgraded.
(2) Downloaded drivers from the motherboard manufacturer's web site.
(3) Scanned the system with AVG, Spybot, Lavasoft and Aries Remover.The first two for viruses and other malware, and the last two for rootkits since I was told that I might have a rootkit infection.
(4) Reinstalled Windows 7 but to no avail.
Some details about my computer:
Biostar Tseries motherboard.
Athlon AMD Phenom 9650 Quad core processor.
2.3 GHz Processor Speed.
Windows 7 Ultimate 64 bit Operating System.
600 watt ATXPower Supply. Model Number FX600-GLN.
Is there some way for the problem to be solved? Is it a hardware or software problem,
or a combination of both, Please advise.
