|"....i noticed that the heat sink fan didn't seem to be spinning up to its normal full speed. i cleaned it of all dirt buildup but it didn't seem to change anything."|
Some cpu fans can spin slower and only spin faster when more cooling is needed, but I don;t think that's possible unless the fan has 4 wires and connects to a 4 pin cpu fan header.
You probably should have replaced the cpu fan at that point.
Cpu fans or case fans making noise indicates one or both bearings are failing. You're most likely to hear that when the computer has been off for a longer time, such as overnight, then when the computer is first booted.
I was going to suggest your cpu was damaged from it overheating too many times, assuming the cpu fan wasn't spinning fast enough, but I see
"...Ive also switched the cpu, memory,
you've tried another cpu.
Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .
This was the original bad capacitor problem - has some example pictures.
History of why the exploding capacitors and which mboard makers were affected:

- he says there are STILL bad capacitors on more recent mboards.
- links on left to economical available premade or custom capacitor kits, and/or you can ship the mboard to him and he will replace the capacitors for a flat fee (including the capacitors) plus shipping (North America only).

Contrary to popular belief, it is extremely rare for ram that was working fine previously to go BAD, unless you have damaged it by something you did when installing or removing it, or unless it was damaged by some event such as a power failure. Almost always, when you have a ram problem, it's either because the ram has a poor connection, or you have installed ram that is not compatible with your mboard's main chipset, or it's CPU's memory controller if that applies.
See response 2 in this - try cleaning the contacts on the ram modules:
Trying different ram can be a mistake.
Ram that works in another mboard , or any ram you buy or have lying around, may not work properly, or sometimes, not at all - even if it physically fits and is the right overall type (e.g. SDram, DDR, DDR2, etc.; PCxxxx, xxx mhz) for your mboard. In the worst cases of incompatibilty your mboard WILL NOT BOOT all the way with it installed, and the mboard may not even beep - the ram has to be compatible with the mboard's main chipset, or in the case of recent mboards, compatible with the memory controller built into the cpu.
The same applies for testing your ram in another mboard - the ram must be compatible with the other mboard - if it isn't, any results of testing the ram on the other mboard cannot be relied upon to be valid.
If you still have the ram that was installed when the system worked fine, try installing just that ram, if you know which modulesthey were.
See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:
Once you know which module ID strings work in your mboard, you can get them from anywhere you like that has ram with those ID strings.
If you have brand name ram, it is usually easy to look up whether it's ID string is in a list of compatible modules found by using your mboard or brand name system model number.
If the ram is generic, that may be difficult or impossible.
