Hy ,
my pc freezes a lot.sometimes every few minutes sometimes every few hours.yesterday only once today... many times...
could it be hardware or software issue ? how to be sure ?
i suspect HDD issue.
it is still under warranty.

i reinstalled my windows 3days ago.

it is window 7 ultimate 64-bit

amd athlon (tm) II x4 640 processor 3.00 GHZ
GeForce GT 440 1024mb ddr3
msi GF615M-P33 motherboard
4gb RAM

tnx for any help

Sounds to me as if there's possible RAM problems here. Probably the timings or DIMM voltage not set correctly. Have you checked those settings? Have you checked to ensure the RAM DIMM sticks are fully seated?
