hello guys - bit of a newbie here...

i will put OS & details at bottom of post...

OKAY, so i have a computer that will not boot for some reason..I have tried & tried all of the forums and googled to death but no joy and wondered if you guys on this excellent site can help!

It all started with accidentally powering off by mistake, unplugged at the wall in error and then computer died! Since then i have ran and checked all the hardware in other machines, including my hdd and alls fine but just cant get the original computer back up, enter the cmos/ bios or anything

I have only once been able to boot the system into full xp - and device manager showed missing RAID controller - downloaded new driver and now will not boot/enter bios or anything

I have tried dumping using the cmos jumpers/ pulling battery etc to no avail

any help or GUIDANCE would be most appreciated

O/S:                   WINDOWS XP (sorry, do not know version - either home or pro 2002)
MOBO:                A BIT KX7-333R
HIGHPOINT         HPT372
VIA - VT8233A     AMD DURON 700MHz
NVIDIA TNT2 MODEL64 VGA BIOS
PHEONIX AWARD BIOS V6.00PG

Kind regards

Ushie

UPDATE:-

i am now able to get into the bios using battery / cmos jumpers

motherboard has both standby & power on BUTTON lit

now what?I'd start by booting to the XP CD, choosing the first repair option (press "R" when given the opportunity) which will take you to the RECOVERY console, and running chkdsk /r

Anomalous shutdowns OFTEN cause hd errors. Let's rule that out (or repair them) and then see where we are.
