can anyone help with my problem? the problem occured almost two months ago when my pc starting freezing and i don't know why... could it be the HDD? the memory? or the mobo? my HDD already have bad sectors in it... and i unintentionally/unknowingly used SDRAM and DDR memory together... could it be the cause? My specs are as follows: Jetway P4XFCU motherboard Intel P4 2.66 ghz 128 SDRAM/256 DDR 40 G samsung HDD i would appreciate any help... thank you!
