My parents PC is having a problem I've never encountered before and I have no idea what could be causing it. Just wondering if anyone here had experienced anything similar. The PC is running windows XP service pack 2. It seems to start up fine but when you sign into your desktop there are loads of application errors like Rundll32.exe and all the usual startup stuff. After that its unusable since windows explorer keeps crashing. Apparently before this occured they were updating WMP 10 to WMP 11. Also the error box states there was an I/O error status in 0x000009c. I've had a good look on the internet for similar problems but nothing is quite the same. Hopefully one of you guys will have some knowledge about whats happening Anyway I'm thinking its either hard drive or memory but I haven't got any spares to test at the minute or something to do with that download. Any suggestions?
