Hi Everyone,

This is the first time I post on this site because I can see a lot of useful feedback here. I recently built a gaming computer around 1 month old, it was great and I was running BF3 on High all day no problem. Until 1 month later I would turn on the computer and no video signal came out.

I took it to a repair guy, he tested my computer for days but he used his own hard drive and said there was nothing wrong with it, and saying how it could run for days and easily pass the test software. He checked my hardware and everything too saying everything is good and there is nothing wrong with it. He said it probably is my HDD or Windows 7 problem. I thought it may have been my hard drive because one time I heard a crack noise from my computer while I was trying to turn it on. So I bought a new SSD drive to try start my computer but unfortunately the same problem exists.

If I was to isolate the factors from the repairman and my home, it may be either my monitor/DVI cable or power supply/power cord that is faulty. Note that my LED monitor works fine with the VGA cable that goes with my other computer, so maybe the DVI slot is faulty. The sound, fans, lights all seem fine also. I doubt it is the fan because it never crashed during a game, it only can't start up.

Can anyone give me some feedback. Thank you for your time!


Specs:
-Windows 7 64bit
-Asus P8Z (Motherboard)
-Intel i5-2400 (Processor)
-8 GB Corsair DDR3 (RAM)
-Gigabyte GTX560 TI (Graphic Card)
-OCZ 120 GB SSD (Hard drive)
-Corsair GS600 (Power Supply)
-No extra fans
 
Take out your GTX 560 Ti and use the onboard video if you can. If you get no problems then I'm going to say your graphics card is at fault. It could be your monitor's DVI ports, sometimes they go bad, can you try a different monitor and see if you get the same problem? I kind of doubt it's your hard drive.
 
I think you have already figured it out. Since you know the LCD works with VGA, get a cheap DVI to VGA adapter (your GPU might have came with one) and try that. If you get a signal, your DVI cable or monitor port is bad. If you don't get anything, then change your power cable. You will not have a bad PSU as that would have been detected by the tech that looked at it.
 
Just try to an other DVI port. That will do the trick :) Or like "wolfeking" said, get an adapter for a DVI -> VGA.
