Most disk io errors are impending hardware failures. Add Dell what diagnostics they want to run.
I keep getting a message Disk I/O error everytime I sign into Skype. I am running Windows 7 on Dell 2350. I am using Mozilla Firefox as my web browser. I have tried turning off my Anti-Virus as was suggested by some people but even that hasn't worked. Any suggestions?
