Hello forum, recently I went to my local computer store and picked up some thermal paste and an air duster for some Pc maintenance. I took out my Cpu chip. Cleaned the existing paste well then applied the new. I put everything in back correctly but now when I turn my Pc on the led lights are on the fans spin but my monitor keyboard ect has no response or display. Ive tried the steps on your sticky thread to troubleshoot but nothings worked. No beeps as well and the computers virtually silent when on.

CPU: amd fx 8150 8 core black edition
gfx: gtx 750ti
Windows 7 ultimate
Mono: 970 extreme3

You shouldn't need to take out the CPU when cleaning off thermal paste. You have more than likeley either damaged the CPU pins is someway or damaged the motherboard. If you have a spare CPU to test in the motherboard it would help diagnose the problem.

I applied a pea sized dot. Then spread it evenly. Also I checked if pins were bent it doesn't seem like it. Unfortunetly I don't have a spare Cpu to test

I would suspect something is not correct correctly after your maintenance.

Due to your socket being AM3+, you can pick up a Semperon CPU for around $20-30 new.. you could pickup a second hand one and it will be even cheaper.

Make sure that the CPU locking lever is fully engaged.

Unplug and re-plug in the 8-pins CPU power connector, the 24 pins motherboard power connector - make sure that the latches engage. Check the CPU heatsink fan connector.

Ok soot appearssome of my Cpu pins are actually bent whenn close examining it. How do I go about fixing them?

A credit card has been used to put them all in a straight line.
In aircraft maintenance, we often used a mechanical pencil to straighten connector pins.

However you do it...do it carefully and gently.

Can you post a pic of this?

Straightening bent pins – CPU/Socket (by Ubrales)

Here are two methods to straighten bent pins. Both methods can be used in succession, or separately, and are proven methods used frequently in high speed automation, especially in the electronic connector industry. The same principles apply to manual straightening too.

Method 1: Combing.
As the name suggests, use a hard plastic flat piece in between the rows of pins, horizontally as well as vertically. Repeat. If the desired level of straightness is obtained, stop. This method works very well in high speed automation, but may not yield desired results in manual operations. Proceed to step 2 if necessary.

Method 2: Pin Straightener.
After combing to obtain a reasonable level of straightness, use a pin straightener. A two-inch long piece of hypodermic tubing which will snugly fit over the pin will work well. About 0.002”/0.003” clearance between the pin and the needle is ideal. You can try a suitable mechanical pencil (the pin may fit in the tube for the lead). With this method, the angle of the bend will be clearly accentuated and visible. Carefully straighten in the opposite direction, taking care not to over-bend.

There are some videos similar to this one - http://www.youtube.com/watch?v=EdDccsbv5hA that will help.

A big plus would be a set of watch-maker’s tools, like precision pliers, miniature screw-drivers; especially a pin collet.

If a pin is completely broken off, no need to panic. Straighten the broken pin and carefully drop it into the place it belongs. Check for functionality.

Some pins are unused, and some are seldom used in CPU functions. So, hope for the best.

The 'combing' technique is a well-known high speed automation technique used widely in industry, especially the connector industry. Just look at the Parallel ATA connector header on some motherboards. These insert-molded (or stitched in some designs) pins are combed, bent 90-degrees, and then combed once more to ensure true position of the pins. Same process for any connector with several pins.

Remember to wear an anti-static wrist band when you attempt this.

Also, please do not spread the thermal paste after applying, the heatsink does that for you. Just apply on a pea/bead sized dot or however you like to then put the heatsink and lock it in. The pressure from it is more than enough to spread it over the area on the heatspreader where you need it without all the air bubbles you'd get from manually spreading.
