Someone or something has been trying to ping my computer and each time it comes from the same source 38.116.157.132 (location: Denver). It comes up as "ICMP Ping" or "Port xxxx (sum random four numbers)". My computer starts freezing a lot and a blue screen of death appears saying that there's some kind of error. Is someone trying to hack into my computer? The same thing happened to my computer only a month ago..the only thing I could do was replace the hard disk. I don't want to go through the hassle of reformatting the hard drive again. If there's any way to fix this problem...any and all info would be much appreciated. Thanks!
