yeah a rebuild, i re seated the cpu, new thermal paste, reseated ram, graphics card, unplugged all mobo cables and fit them back into all devices e.t.c.
i cant back up all my files, i formatted cause it wouldnt let me get into desktop even in safe mode. wouldnt let me repair either using the win xp cd.
i did do a clean install of xp, and even tried creating a new raid0 array. when it loads to desktop, the drives still only show partial size, and its still messed up with pauses, loud noise e.t.c
yeah even though alienware is expensive, you get 3 years of hassle free pc for an extra $500.
