So I have this Gateway LX6200 that a friend gave me. At the time he replaced it, there was a known memory issue that he resolved by replacing the pc. AMD Phenom x4, 8gb ram, Windows Vista. I opened the side to see the RAM to see if I needed 2 or 4 RAM chips. dirt EVERYWHERE! I began to use compressed air to blow out the dirt when i noticed the heatsink had dirt packed in the slots. Unable to get it all out, I removed the heatsink - with, to my horror, the attached CPU. The CPU lock in place, looked to make sure nothing came loose from the CPU.Everything looks inline and in place. After a thorough cleaning of the mb and all the fans, drives etc, I returned all the parts back to the original location. Trying 2 RAM chips at a time, i turned the pc on. Power button blinks blue. Fans spin, CD drive does a wake-up spin, No beep, no BIOS, no nothing! adjust RAM, repeat, adjust RAM, repeat. Nothing. I have reset the BIOS (hopefully) but removing the battery as well as moving the BIOS jumper.

I have tried to follow all the threads, but to no avail. The only thing I have not done, which I do not know if that is an issue, is not replacing the paste to the CPU/Heatsink. The only reason why is that is I need to remove again, I cannot without having to pull the CPU with the lock in place again.

Oh yeah, I also borrowed a friends PSU to test. Same results.

I am thinking I will have to replace the CPU and/or MB.

I would love any recommendations. Thanks in advance.

true, but i don't think that's his problem.

It sounds like you have a short. Blowing all that dust and dirt around probably caused a short somewhere, likely on the back of the board. Take the board, gpu ram, everything out of the case. Clean the board first with air, then with qtips and rubbing alcohol (90%), clean all the parts with this combo, front and back. All the sockets and slots get through compressed air blowing through them. Make sure the cpu socket is cleaned out with the compressed air.

Make sure you wait a bit for it to all dry up, then rebuild it. clr_cmos...
Its probalby toast as nukemaster above said a gentle twist side to side always breaks the cpu and heatsink loose, It always a good thing to let the system run a few mins then power down and release the electric by unplugging the cord and pushing the power button. when the chip is warm it will break away from heatsink better.

Let's chalk this up to the ID10T error. After looking at several more threads, and upon closer inspection with a magnifying glass, my wife's glasses and a really bright light, I found two pins on the CPU that had been bent. Carefully using a sewing needle I was able to get the pins upright, then using a suggestion about an empty mechanical pencil, straightened the pins. After replacing the CPU and heatsink, I turned the pc on with joy that I heard a BEEP and watched the BIOS screen then Windows start up screen. All is well. LOTS of lessons learned - as well as a deep respect for all the wisdom you folks add to this website. Thank you all very much.
