|Did you properly install any metal mounting posts ONLY where the there are holes in the mboard for screws to pass through that attach it to the metal case, if the mounting surface does not have raised integral bumps for that ??|
If you are re-using a case, did you make sure there are no existing metal mounting posts under the mboard where there are no holes for screws in the mboard ?
Did you unplug the case/power supply, or otherwise switch off the AC to the power supply, at ALL times when you were plugging in or unplugging the card(s) or ram or wiring connections ?
If you didn't do that at ALL times, ATX mboards are always powered in some places, including some contacts in the slots, even when the computer is not running, as long as the power supply is receiving live AC power (and is switched on, if it has a switch) - you may have damaged something ! !
"....my hand that was touching a metal on the window of my house to prevent damage on devices, ..."
If the metal framed window is in a wood framed wall, or if it is in a metal framed wall but the windows are mounted on plastic tracks, it may NOT be grounded !
Static electricity discharges are generally not a problem, unless you have the computer in a room that has wall to wall carpeting made of synthetic firbres (any carpet with cotton in it dissapates - nullifys - static electricity), and the relative humidity in the room is too low, which can easily happen in the seasons when the outside temp is below freezing and the heating is on, especially if your heating is via hot water or coolant rather forced air (e.g. an apartment) .
If you are concerned about static electricity discharges, if you switch off whatever the computer is plugged into, such as a power bar, rather than unplugging it, the computer is still grounded when the AC power is switched off, assuming there is a continuous grounded connection all the way back to your power panel as there is supposed to be.
You can't hear mboard beeps unless a (computer case) speaker is connected to certain pins on the mboard, or unless there is a built in speaker like device built into the mboard (very rare for newer mboards). Some new mboards come with a small speaker like piezo device you can connect to pins for a (computer case) speaker on the mboard.
Try this - I'm assuming you have everything connected properly ....
Make sure you have a speaker or speakers or the equivalent connected to the mboard so you can hear mboard beeps (see your mboard manual if you need to).
Remove the AC power to the case/power supply.
Remove all the ram.
Restore AC power.
Try to boot.
If nothing else is wrong, you will get no video but you will hear a pattern of beeps that indicate no ram is installed, or a ram problem.
E.g. 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.
If you still hear no beeps....
- if you did NOT remove the live AC power at ALL times when you were fiddling with plugging in or unplugging components or wiring connectors, you may have damaged the power supply or the mboard or components installed on the mboard.
If you can borrow a PS from a working desktop computer, try that.
- did you confirm that the cpu that is installed is in the cpu compatibility list for your model on the Asrock web site ??
That list shows you whether the model must have some minimum bios version or higher in order to support the cpu. In some cases, if the specific ios version the mboard presently has isn't high enough to support recognizing the cpu you are trying to use, the mboard will NOT boot when that cpu isinstalled - in that case you have to flash the bios to a newer version when a cpu the present bios version does work fine with is installed - THEN the cpu you want to use will work.
- did you connect the 3 or 4 pin female wiring connector from the cpu fan to the proper cpu fan header ??
- all new and more recent mboards require that you connect female wiring connectors from the power supply to TWO sockets on the mboardsurface - the main 20 or 24 "pin" one, and a smaller one elsewhere on the mboard. Did you connect BOTH of them ?
If you DID hear the beeps for no ram installed or a ram problem, it could be the ram was not properly seated, or, you may have bought ram that is NOT compatible with using it in your mboard, which is COMMON these days !
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....
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.
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.
