|Did you REMOVE the AC power to the case AT ALL TIMES when you were fiddling with connections and components inside the case ?|
If you didn't, the ATX mboard is always powered in some places even when the computer is NOT running, as long as the PS is receiving live AC power (and it's switched on on the PS itself), and you can easily damage something, even when you merely plug in a drive.
Phoenix amalgamated with Award years ago.
Newer Phoenix / Award bios versions often use Award bioses / bios updates, unless they're for a mboard made by Intel.
I downloaded a bios update for your mboard model and examined it's contents.
The bios update is a *.bin file which indicates the mboard has an Award bios version.
(Phoenix bios versions have *.rom bios update files.)
A pattern of beeps that indicate no ram is installed, or a ram problem.......
for an Award bios or a bios based on one, that's often a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously.
It probably produces the same beep pattern when no ram is installed.
You have no video and the mboard will not boot all the way when you get that beep pattern.
REMOVE the AC power to the case and....
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
If that doesn't help,
- if you have more than one ram module, try one of them at a time
- try each ram module in each ram slot
Examine the ram slots with good lighting
- look for crap that shouldn't be there in the bottom of, or on the sides of, the slots - blow it out if you see that
- examine the ram slots for evidence of damage - damaged or missing (zapped) contacts - black carbon deposits - plastic has been melted - if you see any of that, you have, or someone has, installed a ram module backwards in the slot and then attempted to boot the computer - both the ram slot and the module that was plugged in backwards are instantly fried and can never be used again. If you clean up all of any black carbon deposits, and melted plastic that bridges contacts in that slot, the mboard MAY work fine with undamaged ram in undamaged ram slots.
Typically there is one or two missing (zapped) contacts on the ram module in that case.
"I also took a look at my CPU & it has virtually no gel on it & what was there was black."
That doesn't sound good.
However, one of the least likely things is the cpu is dead.
Modern mboard bioses will shut down the mboard automatically when the cpu gets hot beyond a certain temp, to prevent the cpu from being damaged. If that has not happened previously,your cpu is probably okay.
There only needs to be enough thermal compound or thermal grease between the heat sink and cpu to coat the cpu with a very thin layer that covers the entire top of the cpu.
Even if that wasn't your case, if there was thermal compound or thermal grease in the center of the cpu, it's probably okay.
Thermal grease (pure silicon grease) is nearly clear when in a very thin layer, but thermal compound can be any color.
