Solved Why Im I getting no signal on my monitor?

Gigabyte / G31m-es2l

Specs: Windows 7 Ultimate, Intel Core 2 Quad 2.66 GHz / 4094 MB
I been slowly (moths) making changes to my old Gateway 838GM. I went from an Intel 915G mobo with 1gb of ddr1 ram with an intel pentium 4 and its crappy integrated graphics to a gigabyte G31 with 4gb of ddr2 and I got a nvidia gt220 and an intel core 2 quad q8400. (I know its not a high end rig but it gets me playing all the games I like and dose what I need it to.) Everything else is the same; same PS same cd and dvd drives same hard drive and same case.

It had not been giving me any problems, but I couldn't even dream of overclocking with that same cpu cooler. So I went and purchased the Cooler Master Hyper 212 in order to get my cpu to at least 3.0GHz without getting higher than the Tcase on any of the cores on full load.

That is when my problem started. After installing my new cpu cooler master I went and pluged everything and turned it on, but it didn't turn on. I though I must have got the power switch front panel connector connected wrong, but they weren't.
When I finaly got it to turn on, everything seemed normal accept that my monitor wasn't giving me any signal. I couldn't even get the cd or dvd drives to open althoiugh it was on.

I put everything back (the old cpu cooler) thinking maybe the ps isn't providing enough power for this massive cpu cooler. But it doesn't specify the minimal power requirements, so I had my thoughts of that being the problem.

I put everything back to how it was before, but this time it wouldn't even turn on.
When I would plug it in a little green light on the back of power supply would flash on and off. I finaly got it to turn on again but now the hdd led and power led aren't on and I am still not getting signal from eather of my VGA cables. (one connected on my monitor and than tryed the one connected on the tv.)

I don't know whats going on! I need help before I go and purchase what I need.
PLZ!! fingers or mclick or anyone in this site who can help

Is it the power supply? Is it the motherboard that got fried is it my video card?

Just guessing now. I am leaning to power supply. Often they will fail partially at first. It is possible that you may have damaged the motherboard but I am thinking only if you hooked up something wrong and shorted it. I am betting that the original power supply was way under what was needed for your cpu and motherboard alone. I think what you have is a 400 watt psu and that cpu alone, if I remember right, requires at least 350 watts by itself.

Note: When it comes to a power supply don't buy cheap just to hopefully get the computer going. They can be bought for as little as $15 I've seen. These if they work at all useually don't last very long. Also I recomend you go 150 - 200 watts over what is needed. If you attempt to multitask or play one of those games this causes more heat. More heat can in the end cause a bit more of a power draw. So if your on the edge of what is needed you just exceeded it.

Thank you very much...

Yeah, my power supply is only 300w, so I defenetly have to get another one. Thanks for the link.

But what if my motherboard is fried; would it be safe to hook up a new powersupply to a damaged mother board?

Again, thank you for answering.

If you have not seen any smoke then look the board over real good for areas that look burned or bubbled up. Look at the backside of the board as well. If you don't find any I would chance it. Good opertunity to check the standoffs one last time as well.
