Windows 7: Problem Booting Up

Problem Booting Up

Windows 7 Home Premium 64-bit
Intel Core i5-4670K 3.4GHz
1 4GB RAM Ballistix
1 8GB RAM Ballistix
Corsair 500M power supply
Western Digital 1.0TB hardrive
Intel Desktop Graphics Chipset

Was running a Gigabyte GTX-660 and had bought and installed a EVGA GTX-960. I'd also bought the 8GB RAM stick as one of my 4GB RAM had a short. Well I uninstall the 660 and the old RAM, install the 960 and the new RAM.

The power turns on, but my rear aux fan doesn't power on and there is no activity in the hard-drive. My keyboard doesn't seem to be receiving any power and my monitor stays blank. I check and double check to make sure the GPU and the RAM have been sat properly and it all looks good. The power supply hooked up accordingly and nothing out of place. So I do a bit of tinkering. I put the power for the rear fan in a slot beneath my GPU and it turns on, but that doesn't solve any other issues.

I then removed the GPU entirely and detached the hard drive. The monitor and keyboard become responsive and notify me there is no drive to boot from. I re-connect the drive and boot up and everything works fine.

I decide to re-install the 660 but the problem persists again, the display stays blank and the keyboard remains inactive. So I'm suspecting I've a short somewhere in the motherboard, I've a power supply going bad or I've somehow shorted out both GPU's. However when the 660 is plugged in and seated the fans turn on, but nothing else.

At the moment I've no GPU installed and everything seems to work just fine.
Thoughts? Do note I'm not to savvy with computers. I've only got the basics down.

Update.
Fiddling around, I popped the 660 back in and started up. Nothing, hit the power switch, waited a few seconds and tried again and now the PC starts up normally and the 660 is detected and running properly. I'm thinking there is a short somewhere but I can't quite figure it out.

Went back to the Microcenter and found the rep who "helped" me out.
Turns out he didn't know what he was talking about. A very simple solution. Picked up a 700W PSU and things work fine, though there is still an unseen issue somewhere. Everything powers up properly though I did a few shut downs and boots and the same problem still persists with the rear exhaust fan and no hard-drive activity. However if I disconnect power, turn it back on and try again things work all proper.

Check your connections.

Unhook the fan you have been having problems with. Leave it unhooked for the time being. Then see if you have the same problem.
Watch your temps.

Look even though the PSU is new maybe it is worth checking it out it is not out of the realms of possibilities it is not functioning correctly and using this takes no time and will eliminate any voltage discrepancies.
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
See this for the rail voltage info
http://www.tomshardware.com/reviews/power-supply-specifications-atx-reference,3061.html (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.
Use PART A:

PS in your specs the motherboard is listed as MS-8750 ?? what is the brand??

Layback: Fan is unplugged.

ICIT: Downloaded the HWi and to be honest, I don't know squat about Voltages. I know what I'm looking at for the most part here and have located the section referred in monitoring the voltages.

My motherboard, MSI z87-G41 PC Mate(MS-7850) (Nuvoton NCT67790).

Now here's a weird thing. I have my tower tilted sideways a bit toward the side the motherboard is on. And everything booted on normally. I did a full shut down twice and it boots on normally each time. I've kept the fan unplugged and temps seem fine.

Ok mate the volts are fine and what you say about tilting the machine is leading me towards perhaps the board is not grounding properly to the case though the blacks on the 24 pin plug should take care of that issue. It might be worth just reseating the plug ( plus all the fans etc) and make sure the screws holding the board down are firm - but please take care NOT to over-tighten them - very easily done.

The fan I would be inclined to ditch it and just get a new one as the one you have may just have faulty windings or the little controller circuit board a bit out of whack. It could even be something like the bearing is shot which allows the spindle to angle over making the fan jam.

If you see my pic and it is similar to the one that is causing a problem you will see what I mean.

PS I meant to add if the connections on that fan are shorting out then it will account for some of the problems you are having.
