Hmm... I kind of afraid to mess with hardware, as it generally tends to
create mess...

However I tried CPU throtelling and had no luck before. The CPU is:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 2
model name      : Intel(R) Celeron(R) CPU 2.80GHz
stepping        : 9
cpu MHz         : 2791.511
cache size      : 128 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2
wp              : yes
