This is going to take a bit of explanation. So three days ago I installed crysis, i know its been 3 years. That is the last change I made to my system until today. Today, my modem started loosing and gaining connection every 5 min or so. I called up comcast and asked them what to do. The tech suggested that the modem was faulty and that I get a new one. So I ran out to the local comcast location and got a new one. So I plug it in as usual, and then my system locks up. I thought that was a bit odd so I rebooted and then after I put in my password, none of my startup programs ran. Thinking logically I unplugged the modem and restarted the machine. Everything worked just fine. So I plugged it back in and another lock up. I decided something was wrong with the modem and got another new one. Same thing happened with this one again. Then when I restarted this time I couldn't even get into windows. All I got was a white screen after I put in my password. I did a system restore and things seem to be working fine, but it's only been about 20 min. If anyone can shed some light onto this madness I would be very appreciative, because my range of knowledge is limited. I am running windows 7 x64 System specs are as follows wolfdale e8500 Foxconn Blackops motherboard (yes its model name is blackops) 2 ati hd4850's in corssfire 2 gigs of patriot ddr3 ram (i forget the model number but I did a compatibility check when i bought it) WD raptor 150 gig hdd thanks to anyone who helps in advance!
