Computer wont boot up after coolingpastechangement

Hello guys!

I have a problem, I will describe so easily as possible, here we go.


30minutes ago, my brother flipped out on me and told me to reformat his computer, before doing so, I checked up his system, and found his temperature on his CPU to be 85degrees celsius, which is 185 Fahrenheit for those of you who use that scale. The reason why he wanted me to do that reformattingoperation is that his computer was working slow, took several minutes to boot and so on.


I opened the case, and found the CPU fan not correctly installed, proibably caused by a stupid movement of the computer. The system was working properly and very good as it recieved to our house, but now it's like this. I removed the fan from the mobo and scratched off the now very dry and useless coolingpaste, took away the cpu and polished the surface and put on new paste on it. Reinstalled both the CPU and the fan upon, reconnected the 8Pin mobo power and fastened the fan pins. Also used the vacuum cleaner to "suck up" all the dust and unwanted particles in the case.

Reconnected all powercables, DVIcable, Ethernet cable, speakers, mic and such, and started the computer
The fans start spin and the HDD is spinning, the sound is recgonizable

Although the monitor ain't showing anything at all, what could this be? Netiher Mouse, keyboard or any LED's indicating workin system(except for the powerLED and a wireless card LED and the moboLED)




Please help me out



Regards!

I almost know this list withoud reading it. I got a checklist in my head, similiar to this.

I dripped some paste beside the CPU socket, but nothing on the mobo.

What could happen if any paste touched the CPU pins? I am pretty sure it didn't, but what if? Could that cause this problem to occur?

Thermal past on CPU pins may or may not be a problem - depends on the paste, because some are electrically conductive and some are not. You could carefully remove the cooler and CPU to check for that. But while doing so, check how much thermal paste in there. Too much in a thick film will actually interfere with proper cooling. The paste maker's website often provides a good guide - I know Arctic Silver has instructions.

Well, this is an unwelcome thought. But, static?

Using a vacuum cleaner on a motherboard is asking for trouble, especially if the air is cold and dry. The moving air creates static in the hose.

Since 85C is over the limit for any CPU, you could have damage from that. You have not given any list of parts that I can see, so I can't say exactly how far over the limit the CPU went.

If a part is going to be damaged by static, it's usually the motherboard. The only thing to do at that point is replace.

Good luck, and please let us know what the verdict is.
