System freezes

[csawjer]

After Reboot system hangs in stage "grub loading . please wait". Disk is active, CTRL+Alt+Del force a reboot
CTRL+ALT+PRTsc +REISUB does nothing

System has been successfully installed. Reboot worked. Then it started to become sluggish with high disk activity. After that the reboot would not bring up the system anymode.

Memory 512MB, 3GB Swap, Acer TravelMate 240 Laptop

How to find the culprit?

Re: System freezes

I would:

Start with live CD
Run in the konsole ( unmounted partition):

sudo fcsk /dev/hda1

or sda (hardware !). Only check.

man fsck

FSCK(8) FSCK(8)

NAME
fsck - check and repair a Linux file system

SYNOPSIS
fsck [ -sAVRTNP ] [ -C [ fd ] ] [ -t fstype ] [filesys ... ] [--] [ fs-
specific-options ]

DESCRIPTION
fsck is used to check and optionally repair one or more Linux file sys‐
tems. filesys can be a device name (e.g. /dev/hdc1, /dev/sdb2), a
mount point (e.g. /, /usr, /home), or an ext2 label or UUID specifier
(e.g. UUID=8868abf6-88c5-4a83-98b8-bfc24057f7bd or LABEL=root). Nor‐
mally, the fsck program will try to handle filesystems on different
physical disk drives in parallel to reduce the total amount of time
needed to check all of the filesystems.

If i get errors with fcsk:
I would install smartmontools ("virtual" installation with live CD):

sudo apt-get install smartmontools

smartmontools - control and monitor storage systems using S.M.A.R.T.

The smartmontools package contains two utility programs (smartctl and smartd)
to control and monitor storage systems using the Self-Monitoring, Analysis and
Reporting Technology System (S.M.A.R.T.) built into most modern ATA and SCSI
hard disks. It is derived from the smartsuite package, and includes support
for ATA/ATAPI-5 disks. It should run on any modern Linux system.

Run in the konsole:
(hdx)

sudo smartctl -a /dev/hda

or
(sdx)

sudo smartctl -d ata -a /dev/sda

man smartctl

SMARTCTL(8) 2006/12/20 SMARTCTL(8)

NAME
smartctl - Control and Monitor Utility for SMART Disks

SYNOPSIS
smartctl [options] device

FULL PATH
/usr/sbin/smartctl

PACKAGE VERSION
smartmontools-5.37 released 2006/12/20 at 20:37:59 UTC

DESCRIPTION
smartctl controls the Self-Monitoring, Analysis and Reporting Technol‐
ogy (SMART) system built into many ATA-3 and later ATA, IDE and SCSI-3
hard drives. The purpose of SMART is to monitor the reliability of the
hard drive and predict drive failures, and to carry out different types
of drive self-tests. This version of smartctl is compatible with
ATA/ATAPI-7 and earlier standards (see REFERENCES below)

smartctl is a command line utility designed to perform SMART tasks such...

If there are no errors (fsck/smart), i would mount harddrive and check disk space and logs:
