Having a lot of trouble with computer and would welcome any help and/or advice please. The mouse freezes a lot and then the whole thing just has to be turned off. When it's switched back on, it recommends a disk check which, if you do it, comes ups with a whole lot of stuff on a blue screen which says something like 'such and such file is corrupt and must be truncated.' Heaps of lines of this info come up on the screen and then the computer carries on as normal. Hope this makes sense and if it does, can someone tell me how to fix this problem? Thank you all in advance!
If your screen hangs (mouse freezes) then you should still be able to shut down by using the Windows key on your keyboard (if you've got such a key - has the windows logo on it) which will bring up the Start menu. Then key in either Shift+U or Alt+U (or maybe even Ctrl+U!) to shut down safely.
Shutting down via the ON button will always prompt a disk check when you switch on again.
If getting lots of corrupt files, I would think you should Defrag. On Windows XP this is: Start / Control Panel / Performance & Maintenance / Rearrange Items on your Hard Disk / Analyse / Defragment.
If the Analysis says you don't need to Defrag. then go to Start / My Computer / right click on the Hard Disk Drive / Properties / Tools / Check for Errors.
To upgrade your Mouse Driver, go to the manufacturer's website and see if you can download a new driver from there, or contact them for help.
For wavy lines on your screen, it sounds like you need to upgrade your Graphics Driver. If you can find out what Graphics Driver you're using you can then go that manufacturer's website and download an upgrade.
