This is my first time posting here so sorry if I'm lacking details and what not. I'm also posting through mobile so I apologize for any grammar issues.

Anyways, Im not sure if Im posting in the right place but I want to ask for help about my desktop monitors.

I have two 24 inch monitors that were working fine since yesterday afternoon and then suddrnly stopped working. It began sometime yesterday night aftrr I tried to hook up my desktop to my big screen TV through a VGA (I believe thats the one? It has a blue color head and has 15 plugs I think) cable since it used to work with an older laptop I had. Turns out it didn't work so I unplugged everything and replugged back to my regular setup with those two monitors, one using the same type of cable (the blue head) and the other with a DVI, (larger white head cable) into my graphics card plugs which was what I used before. Since then, one of my monitors would show a "no signal" display and the other shows nothing with only the monitor on-off light flashing. The screen remains black indefinitely, acting the same as if I had shut down my computer in times before this whole incident.

I've checked and made sure everything in the PC is running during boot. There has been several rare occasions where my PC would boot for about 5 secs only to shut down and reboot for good. (This only occured since the start of this problem and usually only after I unplugged and replugged the Power Supply)

I've also replugged my graphics card and RAM several times, still with no success. I've also tried plugging my monitors straight into the motherboard. I've even tried to use a different graphics card and then plugging both monitors into that. And lastly I've tried to use a seperate 3rd monitor on its own into both of my graphics cards on seperate occassions. None of these have been successful so far.

Any help would be appreciated. I've tried looking around to solutions but haven't found anything yet.

My specs are:
Intel Quad Core
Nvidia geforce gt 640 (my usual graphics driver) and Nvidia Geforce gt220 (I think, this was my secondary/older graphics I used to test) (Note: I do NOT use them simultaneously. I only use the GtT 640 as my regular graphics card)
Corsair TX650 PSU
4 2 GB DDR2 RAM (so 8 GB total)
Cooler Master Heatsink(?)

This is my computer model and base specs. I bought it brand new about 6-7 years ago. The only things that are unchanged since are my RAM, Processer, and Motherboard. Everything else are less than half year old and my Hard Drive was replaced about 2 weeks ago.

Thanks in advance. Sorry if this post is really lengthy, but hopefully it gives enough details about my current problem.

Update: I've also tried removing my cmos battery and reinserting, doesnt seem to help.
