trouble shooting PSU or Thermal Grease

ok i have built a new machine expecting to use the old PSU the specs are as follows:

MOBO: GIGABYTE S-series GA-MA790FX-DS5

PSU: JGE ATX 500W P4-12V (rails are unknown please let me know how to tell the rails and ill gladly post them)

Processor: AMD Athlon64 X2 (skt AM2)

Media Drives: 2 dvd drives (IDE), dynex internal USB multi media card reader

Video card/s: 2 ATI Diamond HD 3870's (tryed to run both first in crossfire than only one)
HDD's: 2 segate 500GB sata HDD's

Misc: TV tuner card (PCI), total of about 7 fans (tho all were not plugged in when i attempted to boot), LCD screen

Problem:
the problem occures durring boot up i attempt to se my BIOS settings and the system shuts down i was told this sounds like a heat issue in wich case the cpu fan is working as is the PSU fan my question is is it posible to add too much thermal paste to the CPU to cause an overheating issue?

The reason for this question is the fact that i had to remove the heat sink in order to install an LCD screen (that arrived later after the fact i had already clipped the CPU to the board and heat sink) i applyed a small amount (or in my opinion a small amount) of artic silver 5 to re seal the heatsink and processor (moral of this story is dont be in a hurry to get ure new machine up and running or u might mess up)

is it possible that my old PSU is just simply too weak to power this set-up?

any thoughts or ideas would be awsome i already tryed to run only 1 PCI-E card but that still didnt seem to make any diffrence

i would like to get to the bottom of this ASAP as i am excited to get this machine up and running thank you for ure time and for reading this post
any other questions please feel free to ask

Yes. Too much is just as bad as too little.

^ Did you scrape the old stuff off before you re-applied AS-5?

Since you can't even run it with one PCIe slot, I wouldn't spend too much time looking at the PSU just yet. See how you fare with the TP re-application first.
 
Heat wouldn't be a problem when first going to start any system up. The immediate shutdown suggests a possible bad board if you simply didn't forget to plug in the 4 wire 12v cpu feed that plugs into the board near the cpu socket. That will stall a system right there fast.

When first applying AS-5 you only lightly squeeze the tube so that only a small amount comes out like what is seen in the photo here.

A slight stitting while applying will see the thin line of silver particles more evenly mixed in with the grey paste itself. You only want enough to see a super thin coat once it spreads across the surface to fill in the gap between cpu and heat sink and then run the system for about 3-4yrs. to warm it up then shut it down overnight.

Artic Silver 5 takes about 200hrs. to see a full breakin period or roughly two weeks depending how many hours daily it is running. The usual advice is not to oc or place heavy loads on the cpu for the first few days in order to see the paste start to bond and heat transfer start to take effect.

yes i did wipe the remainder of the old paste off

are u saying to attempt to reapply the paste i beleive i did place more than the amound in the pic above but as the person who else replyed to this post said somthing about letting it sit for a couple days? any ideas about that?

this board supports both the 4 wire and 6 wire CPU feed where as i chose to use the 6 wire feed ill attempt to run the 4 wire feed insdead and report my findings thank you for that idea

*** pluging in the 4 pin molex has no diffrent results than plugging in the 6 pin molex

duley noted i am aware things are some times made bad but i ordered the testing on this board as well before i bought it but who is to say that thay did it i guess i have been crooked by online stores before tho mostly buying parts to mod my xbox

is it possible that both the 6pin and 4 pin lead may be burned out for the PSU ?

i mean no offense what so ever but i find this statment to be false in my own experiance due to the fact that i am a game console modder and a PS2 (thick model) will even shut down in a matter of minuites if the fan isent working properly or even plugged in for that matter ( tho granted it may be in the PS2 mobo programming not to let it start w/ out the detection of a fan).

**** a couple of additional side notes:
as far as beep codes go im getting one short beep indicating a sucessfull boot and i can actually hear the PSU turn off when the system shuts down (not shure if this is relevant or not) have not tryed to reapply the thermal paste YET

i think i solved the issue im not shure y but the paste did not bond nor spread across the cpu so i simply removed the thermostat wire and removed the old paste re applyed and re assembled WITH OUT the LCD wire between the heat sink and processor and it seem to stay on if im wrong ill b back to post tommarow thanks for all ure help and suggestions on the other hand now im stuck w/ a thermomiter that i dont know what to do with where can i attach this any ideas lol its all good the case mod looked like crap any ways
 
Having anything caught under the hsf is bad news! Once you allow the system to run for those 3-4yrs. on the first night they adivse shutting it down for several hours to see the bonding to start taking place. After the first days you should see temps drop somewhat as the heat transfer increases somewhat.
 
I think you are only supposed to catch those on the very edge not center them under the sink itself lifting that away from the cpu. You have to look carefully at the instructions to see just how to see those go on.
