Hi. I have a serious problem with my computer and badly need help. I have a customised desktop. I had it assembled at the store i bought the parts from. Now the problem is that my monitor does not display anything on the LCD and the PC switches on just fine. The monitor shows only 1 thing: "No Signal" My specs are: a asus m4a79t deluxe mb, amd phenom II 955 be(black edition), thermaltake 700W pwr supply, thermaltake V9 case, G skill ram 4gb, 500gb WD HDD, LG Disk drive, and lastly, a acer P235H monitor. i have checked all the wires inside and outside. All of them seem to be plugged in just fine. i have used this desktop for almost a year now and this is the first time m facing such a problem. Oh, and 1 more thing, my keyboard is wireless(logitech) and when press the num lock ket it lights on the censor but when i press the caps lock key, it doesnt have any effect. Please help me!
