Advice please peeps
Machine started playing up yesterday, locked up when in Windows XP. Had to do a hard reset as couldn't CTRL-ALT-DEL.
Was able to boot in to Windows but it locked up, then it kept restarting before going in to Windows, then displayed a registry error message. Several times a disk read error message would be displayed just after the BIOS.
Gave up and then tried to run WD Diagnostics from a memory stick, wouldn't get past the first bar and time kept increasing.
Switched computer off and installed another hard disk so I could restore from an image. When I let the computer boot up this time it went straight in to Windows (thank God ) and worked fine.
This morning it worked fine but when I switched it on around 6pm it locked up again but after a hard reset I'm using it again.
Apart from trying a HD diagnostics utility again, anything else I should try?
