T60 running very slow, both processors sharing 50% idle

#1 Post by T7TrainingSystems » Wed Oct 07, 2009 4:45 pm

Hi all, I have a T60 (2007-BN5) with 3 gig ram, 7200rpm HDD (about 250gig or something) and it's run a treat for three years now, brilliant machine.

It crashed a little earlier, no alt-ctrl-del response so I held down power to restart it. Now, it does this:

Windows takes 4 or 5 minutes to start and the mouse works fine but nothing seems to respond - taskbar, icons, right-click, etc.

After leaving it for another 5 minutes, the taskbar programs load (I have very few, eg. Comodo)

Previously it would take 2 minutes max from startup to ready to go.

HOWEVER, about 5 minutes after I try to start a small program, it often starts - I got task manager up like this and the program (nothing else) seemed fine when it was up and running.

MORE IMPORTANTLY, it showed 50% CPU usage - the left CPU was going up and down and the right CPU was going up and down seemingly in the opposite to the left CPU... equaling a perfect 50%...! That seems really weird.

Looking at System processes, they're all using 0 except System Idle (50) and Task manager (1 sometimes).

It's a dual installation laptop (XP and Vista) both on a partitioned HDD so I have the luxury of trying it with the Vista installation - it works perfectly fine, so I assume the problem is the XP installation or a problem with a part of the HDD that has XP on it.

I've already backed up everything successfully so... tonight I'm going to go through this process:

- Run a virus check through Vista on the XP partition
- If no luck, reinstall XP.

If anyone has some advice or something I should do before losing an evening/morning to reinstalling, please let me know, thanks!

Especially frustrating because I was intending to upgrade to Windows 7 when it comes out late October... not happy having to reinstall XP to use for such a short amount of time :evil:

Boot times are most correlated to the hard drive. If it seems like it takes a long time to boot that would be my guess as to the reason. Maybe you can run PC Doctor in Vista to see if anything comes up with the drive?
