As I understand it, your computer stops somewhere in the booting process, you hit the reset key, and then it boots and runs fine with no problems until you turn it off and have to repeat this process upon turning it on again. Where in the booting process does it stop? While Windows is loading or before? (If it is stopping while Windows is loading, that looks more like a software problem.) I doubt that you damaged the cpu, or your computer would not run fine after the reset. Compound on the pins might cause some intermittent connectivity problems, but you are not experiencing this symptom. You are very lucky, as the biggest danger to your cpu was not the compound, but static electricity - which could have damaged it while you were cleaning it. My guess for your problem is a weakening power supply. It doesn't have quite enough oomph to get everything going, but when you reset it, the disks are spinning so the higher start-up voltage/current is not required. This is just a guess - others may have a better suggestion - so don't go out and buy a power supply just yet; after all, it IS working, just a little extra boot time is required. (If you could borrow a working power supply from another computer, you could easily test this.) I suggest that you make sure all your connections are tight - sometimes when working inside the case you loosen something. Your symptoms don't seem to indicate that, however.

I wanted to have it on my system since it has the newer USB 2.0 on it. It also uses the newer DDR rams for its main memory. My old motherboard is an Iwill kk266r, that has a 640mb PC 133 RAM I swapped my AMD Athlon 1000 CPU to use the K7VTA3 mobo, and also using a 128 DDR PC2100 on it. Since I noticed that it has slowed down the loading of my applications, I decided to just revert back to my old configuration using my old kk266r motherboard. But in the process of cleaning out and replacing the thermal compound on the CPU, I accidentally spread it on some of the other parts of the CPU other than the die and tried to remove them as best as I can using isopropyl alcohol, paper towel and cotton buds. And when everything was back in place, I fired-up the machine and it would not boot unless I push on the reset button on the front panel of the tower casing. Could the spread of the thermal compound have damaged my CPU? Everything is back to normal though after it is able to boot. I have tried isolating the other cards and ram on my system and also changed some settings on my bios but all of it did not help as well. I also took out the battery on my CMOS to clear it but it also did not help. Could my CPU or motherboard have gone bad after messing the application of the Thermal compound? I apologize for the long post but I need your help very much since this is the only machine I have and am using right now. I'd really appreciate any help you could extend with this problem.
