How exactly do you put thermal paste on a athlon 2600 + since the back of the cpu is not all metal, my computer keeps restarting every time it gets hot?
 
First, make sure your heat sink and CPU are clean, Isopropyl Alcohol works well for that. You want to put a very small line of thermal compound (about the size of an uncooked rice grain) on the middle part of the CPU then put the heat sink on. You can spread the thermal compound if you desire but you should make sure it is as thinly applied as possible (too much thermal compound isn't good). Although most thermal compounds are not electrically conductive (or are poor conductors) you do want to avoid squishing compound out into the surrounding IC's (mostly that would indicate you've use too much).

How long do I need to let it set before turning on the computer?

 
You shouldn't need to wait any longer than it takes to get the computer back together. Some thermal compounds such as Arctic Silver 5 have a "curing time" during which their performance will increase a little but that occurs during use, there is no waiting period

I see thank you, now all I have to do is figure out how the unlocking mechanism works on heat sink, if it turns out that is not he problem could the cpu its self be going bad ?
 
If you have an Athlon XP 2600+ then you have one from 2003ish, if its an Athlon 64 2600+ @ 1.6Ghz then its from 2007, either way it is rather old.

Since you are rebooting every time the computer gets hot i would bet that either the heatsink/fan is clogged/jammed(most likely), the motherboard chipset is overheating, or the PSU can't handle sustained power output at those levels anymore.

Does it happen when you start up something intense or does it take a few minutes before it restarts? If it happens immediately i'd bet on the PSU, if it takes some time i'd bet on overheating and give everything a thorough dusting, changing the thermal paste will only do so much.

Well the computer use to belong to my brother in law and I got it when he passed away, it took me a while to figure out what part of the problem was, for some reason when you first turned on the computer the exhaust fan and cpu fan would come on with no problems and had plenty of power, But just as soon as the os would boot up the exhaust fan would shut off completely and the cpu fan virtually no power what so ever in fact if I touched the cpu fan it would stop and I had to spin it again to get it going, So what I did was I got a couple adapters and hooked the exhaust fan and the cpu fan directly to the power supply instead of the mother board and that made fans work at full speed continuously, this seemed to have fixed the problem as I did not have any more restarts, but yesterday when I was trying to watch some online videos it keep restarting, I looked at the cpu fan it does not seem to be clogged and the heat sink is pretty clear, how ever my room was a little hot yesterday, I have the side of the computer off with a fan blowing on the cpu, but it appears when my room gets to hot fan or no fan its starting this restarting again, so far today it has not done anything yet but is not quite as hot as it was yesterday...


 
I think I'd be leaning toward Hunter315's suggestion of the Chipset (I'll include the VRM too) getting overheated, you should be able to put your finger on the chipset heat sink without it burning - keep you finger on it when windows starts, see if there isn't a noticeable increase in heat. Look over the motherboard for any leaking or swollen capacitors while you're in there. Then again, as Hunter315 also points out, the PSU is suspect too
Do you know what hardware is installed? Graphics card(s), PSU, motherboard etc.
