rapidly increasing 'interface CRC error count'
I've noticed my laptop become rather sluggish. It's almost like the computer has a total pause for a second or two eg click start menu it appears but then it can take a few seconds for windows explorer to appear after being clicked. Browsing folders is usually seamless but more often recently I'm getting a few seconds pause randomly when opening folders.
I ran the Dell diagnostics and it passed, but HD Tune Pro shows 'attention' for a 'high interface crc error count'. It increases every time I hit refresh, and is over 45000000.
Should I be worried about this and could the 2 be linked? Luckily my machine has about 10 days of warranty left with Dell but their diagnostic tool says everything is fine...it would be great if someone could give me a pointer so I know whether it's worth fighting with Dell over it.
I've formatted the hard drive and reinstalled Windows and it's just the same.
