Running a intel i5-2nd gen,1gig 256bit ddr5 GPU,8gig ram,win7 64bit is,600w PSU, been using it for some time,then I decided to clean and remove some dust from it. After getting it back up monitor show check signal cable thing,tried to checks all cables and ram slot are on place,PC boot up still no display. Then I found out my wireless lan antenna doesn't work either and can't get internet signal, lan port got fried years ago, GPU fan still working and tried to place the port to motherboard and display shows up, so I guess my wireless antenna and GPU both are died. Any other solution for this before I buy new hardware to get it working
