PC has been working fine but then recently will start up when switched on but no display on screen. Fans will start but no beeps and monitor light remains on yellow + no display. Changed monitor over but same problem. This would happen intermitantly at first but then more often. Then I could get it to work only when I reset the CMOS. Now it won’t work at all. I have replaced the CMOS battery and disconnected all peripherals -H drives, floppy, keyboard, mouse.I also checked the seating of the video card, memory sticks and the processor and tried a different power cable from the PSU for the video card. All to no available. Using NF7-S mobo,Tagan 480 PSU, Corsair 1GB memory,Radeon Pro video card. I think it must be the CPU or video card butI haven’t got an alternative video card or cpu of the same type to try. Tricky when you can’t see the bios at all. Any ideas much appreciated.
