I'm seeing this failure on 8400 to 8600 based video cards. Pretty simple to fix but hard on the owners as they want the video card fixed!
Ok I have an hp slimline desktop that was ''built'' on the hp site. Intel quad core 9300, nvidia 8600 (I think) Has a foxconn motherboard. Windows 64 bit. Ok, got that out of the way. Have been having problems with the monitor recognizing the computer for some time. All the lights, hard drive power power up in the computer just fine, just cant see whats going on due to the monitor not being recognized. But..this is usually remedied by either turning the 10 strip off for 10 seconds and turning back on, or, and most cases unplugging the power cable directly from the back of the tower. This has worked until the other day, now I cant get the monitor on at all despite all my hack tricks. I even talked trash about the computers motherboard and told it it had better recognize or else!! lol. The monitor is an hp monitor as well, its an lcd and goes to sleep after telling me there is no input signal. I have tried both the vga and dvi, nothing....So what could this be? graphics card? Mother board? Power supply? If its the graphics card I am wondering if taking it out and re-inserting it might help at all? Any help would be much appreciated
