hello people... so i was trying to figure out why a friends notebook (i5-quad core) was working sooooo slow and having crashes and freezes every literally 15 seconds... i checked and everything seemed to be ok... my friend asked to remove windows 8 and install seven so i was like ok.. maybe a fresh os install will fix it..... aaand it didnt.... again..random freezes opening my documents... ages to install little apps.....(spotify took about 30 min.... a little execesive dont you think?) and so i was scratching my head when i opened task manager and noticed one of the cores just doing nothing..... like completly dead. it would do a brief peak of activity and then nothing again while the other 3 cores were working just fine... my question is... can it be a dead core??? how can i check if its dead or something in the bios is miss configured?

sorry for the extremely low info...its a lenovo core i5 with 4 gb of ram ...intel hd ... i dont have the computer with me at the moment...

the computer is a year old.. she hasnt dropped it buuut no the most delicate person... although i really dont think is enough to damage the hdd...i checked if drivers were up to date and that is ok... as for virus... i know it had some crap before... and now that you mentioned.. eset caught a dns injecting what not and blocked an ip... can it be that?? maybe?? it just seems diferent from the fact that one core would simply not do anything...

definately a hdd man. Ive had the same problem for my sisters laptop. she might be embarrassed to admit she dropped it, or maybe dropped it subconciously. Try running crystal disk mark and maybe atto. But from experience, replace the hdd.

It's the hard drive, more than likely. Or it's overheating and it's throttling like crazy.

 

But probably the HDD.
