My PC was been booting up fine using onboard video, I reinstalled my GTX 750 Ti video card yesterday, it was not working, so I removed it and plugged the video cable back into the onboard video, now my computer will not boot ?

Cleaning all contacts and possible replacing battery(read manual evtl. google) and cables helped me often. PSU and videocard are those which dye often.
Cleaning done with hard erazor where possible, wiped dust with brush, clean with 90% alcohol(or 70% but then wait a bit till reconnecting).
If old PC from around 2004 then capacitor-plague could have broken out. google.
Have a long thread about that but needs a lot of time and nerves following....
I have a feeling it may be the power supply, when I connect my fan to the power supply it does not spin. Also the power supply has a fan on the bottom that is not working ?
Yes, Power supply is dead. If the fan on it doesn't spin that a sure sign of a dead power supply and computer will not boot because of it.Quote:

Adding to what Doc said, if you use that standalone video card, check how much power it needs to run in your computer. Most say at least, 300W and then you have all your peripherals, printers, USB ports, and your motherboard, memory, etc.

My Current Power Supply is a Therlatake TR2 500 Watt. Looking to replace this, is Thermaltake good name ? Looking at the Thermaltake 500 Watt Smart ATX 12V. 80 plus certified Active PFC Power Supply.??

And I wouldn't trust Thermaltake any more after I had two die on me.
Now I only trust Corsair modular models. Using modular model, you don't need all the wires that come with traditional PSU, so the modular models allow you to use just the wires you need.
Not everyone knows or wants to take the chance on shorting two pins. I use a PSU tester by Asus.Quote:

there are better hints. one must take care finding the right second pin.
pls study sketches etc. carefully. it depends which PSU. first one always black doesnt matter which one.
sometimes the sketches are from top showing the cables.How stupid one can be. One must see the open end of the plug where the paperclip must be mounted. do that in a way it will stay inside.
pls google further
testing psu.
2nd better hint

earlier i used a fan to check PSU. couldnt that replace paperclip-method?
one only needs sata-molex-adapter of fan has molex. it depends situation. new psu no more molex?
Hello, I have another question, I believe I have a issue with my power supply, as my PC will not boot. However I do see see a green led on my motherboard, so this is telling me the motherboard is getting power, Does this mean the power supply is not an issue ??
I wouldn't assume the PSU is ok just because you see a green light. I would swap it out for a known good PSU as a test.
Update, my PC is up and working, thanks. As it turns out, it was not the power supply. I opened it up and checked all connections to make sure they were firmly connected and also unplugged the computer from the power bar, and plugged it into the wall receptacle. I am using the onboard video, I would like to attempt to re install the video card but wil backup some files. And wait a bit while everything is working just fine.
