I bought my 2nd computer and it was great. Good for work and some games. After some time I started to notice that computer was bit lagging and after couple of days my Hard drive started making this anoying sound that pisses me off to this day (http://). And after some days blue screen apeared. Blue screen and this noice, i think i should buy a new HD so i did. I bought almost thesame as old one, pluged in and the new HD started to make the same noice! So the last thing is the RAM, i checked the RAm requirments for my motherboard. Added new ram with new Hd and Pc started working again. 6 months pass and pc started to lagg again. OH no! the the noice came back and again blue screen and other errors. Now im just out of ideas what to do. The new parts just dont stops woking after that small period of time. I dont know maybe it's somting other. HELP!
