Hi,
Yesterday while I was thinking about CPUs I decided to take my after cooler from my pc build (back in January) to check if it fits my CPU so I can overclock it. What happened is that I didn't want to do it in the middle of the night so I decided to put on my stock cooler back on my CPU. After doing so I got a no signal detected from my monitor. I tried everything to solve this problem.
Reseating my video card/ram
Using the other side of my dvi cable
Auto fresh button on monitor
Reconnecting video cable to different slots
I don't know what to do anymore I don't think my GPU is dead or my psu either they've been around since January my entire build is new I have no extra psu to test if it's dead or not my specs are
Amd fx 6300 black edition
Gtx 660 gigabyte wind force oc
8gb ram corsair
550w xfx psu
Any help is appreciated!!!

No my cpu was overclocked by 10% to 3,7ghz from 3.5ghz with the stock cooler before. I don't think thats the problem. I put the stock cooler back on after I thought that the after cooler wasnt the right time to do at night.

did you disconnect anything vital in the process?

No the only thing I disconnected was the cpu fan switch which obviously has to be taken off when switching with a new cpu cooler. I put it back on after I didn't want my aftercooler on.
All fans spin, my led powered fans my graphics card' fans my cpu cooler fan everything. And even if I have my headphones connected to my I can hear the windows start up noise. My computer boots up but like I said "no signal detected" on my screen.

I see, you have any other GPU/monitor handy?

This is my only GPU I have my xbox TV which does not have a DVI port but has an hdmi port. My monitor doesn't have an HDMI port. Yes my card has an HDMI port.

That's the thing I would of already done that but my monitor has no HDMI port just VGA and DVI so the only possible thing I can do is test if my TV connects to my PC, if it does it's not the GPU or CPU problem?

could you try your graphics card in another PCI-E slot, no matter of the speed it runs at.

This happens to me from time to time, what i do is simply turn the switch on the psu on and off.

That was another initial problem, my motherboard only has one PCI-E slot...Never get a £30 motherboard :/ .
But what I did is I connected my HDMI cable to my GPU using the HDMI slot and it worked. So I guess a cable problem with the monitor to the GPU?

But it can't be the cable or the monitor. I only got those 2 months ago. I even returned a faulty monitor that had a power cable problem.

Could it be the fact that I didn't use thermal paste on the CPU Stock Cooler before putting it back on???
EDIT: I just looked at both of the DVI-D cable's pins. They both have one pin which is placed further down than the other pins. It's the 11th pin if you look at it from the big pin to the right pins.
Could this be the problem? If that's not it I just don't know anymore.....

Try and use a different cable.

I figured that out when I found out that my DVI-D to DVI-D cable was busted, so I got a DVI-D to HDMI cable. Or maybe it was my graphics card DVI slot. I don't know but I'm happy it's working again.
