Help!!


I have an HP ze4800 that was working properly until this morning....

I recently installed AVG 7.0.....
plus diskeeper 10.......

I defragmented last night, it performed better.
AVG seemed to be working okay.

Now I cannot get the computer to boot at all...have tried safe mode, will not work.
Will not go back to most recent working position. Will not boot into Windows XP at all.
I have also tried various power sources and running a hard drive test in setup.

I would appreciate any help.

See if this helps:
