wow a  supper old PC, SFF tiny desktop. Compaq = old 

QM57, + Core i3-530 (gen 1 intel)

11 years old max?


step 1 is new  RTC  coin cell, battery , no pCs on earth BIOS works with a dead COIN< period


no coin cell goes for 11 years, or is on he cusp if death even random or by hot cold room

we use a voltmeter below 2.9vdc is the end. replace it first,

some fail in 3 to 4 year , no plugged into wall AC.  per intel spec. that. 


the BIOS must work

the fans must work do they, cpu fan/? spins and actually blows are and not packed in 10 years of lint?


all PCs do this, this old, all do, it is just a fact.

1st. then 2nd HDD bad.


NO warranty answers by me.
