Google for your service manual.

"what could be wrong"

Obviously you didn't reassemble it correctly. Why did you take it apart in the 1st place? And how far did you strip it down? Did you remove the CPU cooler? If you did, did you clean all traces of the old thermal material from the bottom of the heatsink & top of CPU & then apply a fresh dab of paste as per the instructions for your particular CPU? Old paste should NOT be reused & new paste MUST be applied correctly.

Integrated graphics or a separate graphics card? If the latter, make sure that it is inserted properly in the PCI slot and that any power connectors it requires are inserted.

I took it a part to clean it like I said I took it all apart e en the mother board but I didnt take or do anything to it just unscrewed it from the tower then put it back it and im not good with names of the parts I dont know much about them but I took one of the main fans out cleaned it off but it had small gold pooky thing at the bottom that goes into the mother board is that what ur talkin bout the cpu cooler if so I dont know what thermal stuff ur referring to I cleaned the fan and made sure there was nothing in the little square box before I put it back on the mother board

If by little things on the cpu you mean the assorted "pins", then yes if any of those are bent the cpu won't plugin correctly...; and the whole system won't work, boot up etc.

Did you by chance use a vacuum cleaner on the hardware? If so, you may have damaged components due to electro-static discharge, which is caused by the air stream passing thru the hose. Doesn't take much to zap things.

As stated, if you bent the CPU pins but did NOT break off any you can straighten them by using a mechanical pencil without the lead installed. Use a 0.5 MM pencil. You probably pulled the CPU out of the socket when removing the heat sink/fan. You should have come here for advice BEFORE working on it. No need to disassemble anything. Blow the dust out with canned or compressed air. Works much better and is simpler.

There is a lever on the CPU socket on most motherboards. You must release that lever to remove or install the CPU.

Nice tip with the mechanical pencil OtheHill. I've always fumbled through the job with a pair of needle nose pliers.

Why would I use a vacuum cleaner lol I just used a clean rag and dusted the fans off and gently wiped the stuff on the mother board off and if I replace the cpu and install it correctly like I watched online it should work and if it doesn't could it be the power supply or the mother board could just be fried but how can u tell if it is fried

Look at this page, select the CPU that you have and read until you understand the proper application of the thermal compound:
http://www.arcticsilver.com/methods...
If you removed the heat sink with the fan on its back from the CPU then you must clean off all of the old thermal compound with a high quality rubbing alcohol and properly reapply the proper amount in the proper way for your CPU type. The CPU generates a lot of heat and the heat sink needs to be able to remove it. The old thermal compound once you break the seal does not allow a good thermal contact between the surfaces and actually will act as an insulator. With the proper application of the thermal compound the heat moves from the CPU to the heat sink and then via the cooling fins to the air in the case with the help of the fan. Then out of the case by way of the exhaust fan. You can purchase a small tube (only a tiny bit is needed) of thermal compound and any electronic store, it is not expensive and you can use even an inexpensive brand with little difference on most machines.

You have to be a little bit crazy to keep you from going insane.
