cpu replacement, dead computer

So long story short, I replaced my P-6960fx's cpu and now the power button does nothing. No lights on front, no beeps/sound, no fans. I read about all you guys who replaced yours and thought i could do it but now I'm afraid I've just killed my computer for good. I put the original cpu back in but its still rock dead. I replaced with this new t9300 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330350239042&ssPageName=STRK:MEWNX:IT. I ripped the thermal pad on the chipset when removing it the first time, so I waited for some ICD7 to arrive as a replacement since I only had AS5, while i waited for my icd7 (about a week) I left the new cpu in with no heatsink in the case closed, no battery, and no power sitting on my floor (is that ok?). I cleaned all the parts with 91% isopropyl alcohol, put the paste on tightened everything and turned it on (well tried anyway). After removing the heatsink to see what might be wrong i saw that the icd7 had been pushed out and onto the little metal rectangles on the chipset. Would this fry it? It wasn't like the lights came on for a few seconds then it shut off, it just never worked or did anything. I also dropped a few of the 4 cpu screws into the motherboard when working, would that fry it? And i found out that the tweezers i was using were magnetic after the screw i grabbed stuck to it, is that ok? I blew out the case with compressed air throughout the whole process. I dont know what else i could have screwed up or what could be wrong.

Any help or suggestions would be highly appreciated!! Thanks soooo much for reading this!! I really don't want to not have a computer this year at college.

 

I dont know what to tell you... have you tried replacing the CMOS battery? Maybe its just dead and for somereason not letting your system start.

Its rare, but if you hit your motherboard with something with a decent static charge you can fry it... i really hope this isnt the case though mate.

 

The 4 screws hitting the main board could be the culprit. As Kamin sugested remove the cmos battery, and try this with th OLD cpu first.

Also be sure you retighten the locking screw for the CPU. You'd be amazed in haste how many times that is forgotten too..........

 

I shouldn't be the ICD7 on the chipset because it's "Non capacitive or electrically conductive."

Have you tried turning it on with the "hot start" button? (to the right, with arrow) That is what i have to do, and have been for a while, because the cable to connect the button to the motherboard was bad.

 

First off thanks for all the quick reply's! Good to know that the ICD7 isn't the problem. Is the "hot start" button like the media buttons, cause I've have tried those and same problem. I'm almost positive the locking screw is good, I felt the resistance then the give and its in the locked position and I saw it move. So for the cmos battery, I should remove it and replace it with a new one? ( know where I can get one?) And would leaving it unplugged for a week cause it to die, or is it the static charge from the screws or something that made it die? Would it have anything to do with the bios or drivers, I did install a retail copy of vista before i changed out the cpu, but I think I installed all the drivers from the website. Thanks so much guys!

 

Your sure nothing that shouldnt be touching is touching? No shortages or anything? Did you lock the socket after you swapped the CPU?

Alcohol is highly conductive though, and although most of it would have vaporized, traces could be left causing short circuits.

 

Yeah that could be it, after i got icd7 on the chip set I wiped it all down with the 91% alcohol. Is there anything I can do to test components, just knowing what the problem is would be great.

 

Do you have a local repair shop in your area? I knew a place where I am that did laptops and they tested all my components, and confirmed my CPU wasnt the problem, and that some solders and such were blown and needed to be re-done.

This sucks though, basically same thing happened to me and I had to get the MB replaced, $400

 

To test the cmos remove the battery and then the cmos battery under the wireless card. you should be able to then push and hold the power button for about 20 seconds without battery or AC. then replace the battery and with AC power now plugged in only try powering up..............

 

have you tried the media center button. that works as a power button too. try it.

 

when you say "replace the battery" do you mean the cmos battery or the big normal one? can it run without a cmos battery at all? and is the 20 seconds just to get rid of any left over power?

 

replace=put cmos battery back in. You should be able to run w/o the cmos battery but at power up no cmos options will be saved meaning you have to set options in bios like time etc each time you power up.

 

Well since none of that worked I started calling local places including geeksquad for estimates and local place suggested removing and reinstalling the memory to reset it. AND IT TURNED ON AND BOOTED!!! I was thinking this was going to cost me 500$ so I'm so happy right now!! Too bad the old cpu is still in... hope I can get the new one in and working along with my new wuxga screen. Thanks again!! Wish me luck!

 

Very cool, that was my next suggestion, that is to try the memory sticks, but being as it was off for so long and exposed CMOS is always the first trip too take.

 

Thanks for all your help guys, i got the new cpu in and my new lcd screen working. Getting good temps and everything. Thanks again!

 

Whoa nice one nof. How are the FPS boosts in games. Its should be pretty noticeable.

 

All is well that's ends well!!! I love feel good stories!!!

 

Haha wow, im happy you got that working, I know that feeling, whether it will turn on or not, and its no good.
