|"check the cmos battery...try re-inserting it..."|
That has NOTHING to do with your problem.
A dead or too weak cmos battery, or one that has a poor connection or is backwards in it's socket, cannot make your mboard not boot if there's nothing else wrong.
The mboard should boot fine even if there is no cmos battery installed if there's nothing else wrong. However, you would get a "Cmos Checksum Error" or similar message in that case, and have to go into the bios and set at least the date and time.
There are several common mistakes people have made when they have assembled a new system and it doesn't boot normally.
- you MUST remove the AC power source to the power supply when it has been connected to the mboard whenever you connect anything to the mboard or to the PS or make any changes to connections to the mboard or to the PS, and when you plug in or unplug ram or cards in mboard slots!!
If you didn't do that at ALL times, something could have been damaged, including you may have fried the PS or the ram or the video card(s) in (a) slot(s).
- make sure you have connected everything properly - consult the mboard manual - labelling on the mboard can be
Your mboard requires an extra power connection from the PS other than the one for the main connector - that MUST be connected.
Some video cards have sockets that require you connect them to one (or two) power connectors coming from the PS - that MUST be connected for the video to work, and the mboard may not boot if that isn't connected.
If you have been fiddling with the clear cmos jumper or similar, it MUST be on the pinsf or the "normal" mode or similar, otherwise the mboard may not boot!
- You're saying you've installed two video cards.
When you install more than one PCI-E X16 video card, sometimes the additional card(s) require you have do something specific to the mboard on the mboard or in the mboard's bios in order for you to get video from the card(s) other than the first one - see the mboard manual.
- the ram you choose to install must be listed as compatible with your mboard model somewhere - if it isn't, it MAY work in your mboard - or it MAY NOT work. See YOUR RAM and YOUR RAM #2 below.
- the cpu you choose must be listed as compatible with your mboard, and that cpu must be supported by the bios version the mboard has. See YOUR CPU below.
- A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen with new ram, or after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
"6GB OCZ DDR3 PC3 12800 8-8-8 @1.65v"
I know from previous experience OCZ has a crappy ram configurator.The ram for lots of mboard models and brand name systems are not listed.
Select Tools tab - Memory Configurator
System Type - Motherboards
Manufacturer - Intel
Model - DX58SO
I looked up Intel's info regarding the manufacturer's part number for the DX58SO mboard
"BOXDX58SO Single box; AA#: E29331-xxx"
On the OCZ site in the same place...
Manufacturer's part number: E29331
Exact match de-slected, Search - no results
(You could try the specific model E29331-xxx
found printed on the mboard surface, xxx being something other than xxx, but that will probably yield no results as well.)
Searched the whole OCZ site with DX58SO and DX58 - no results.
OCZ does NOT list ram for your mboard model !!!
DX58SO mboard support Home:
Compatibilty - Intel Hardware
"Intel Core i7 Processor"
That's not specific enough.
The cpu you are using must be on this list,
and the mboard must have the bios version specified, or higher, in order to support recognizing it.
If the mboard DOES NOT have at least the bios version specified, the mboard may not boot at all, and you or a technician at a local place may need to install a cpu the bios Version DOES recognize, flash the bios to at least the bios version listed or the newest non-beta bios version, THEN you can install the cpu you want to use and it will be recognized fine.
Compatibility - Third Party Hardware/Software - System memory
No OCZ memory listed !!!
YOUR RAM #2
The cpu's required FSB bus speed must be supported by the speed of ram you have installed, otherwise the cpu cannot run at it's full rated speed, and it's possible but unlikely the cpu may not boot at all if the ram speed isn't fast enough.
The ram you chose may be incompatible with using it in this mboard!
That is a very common problem these days for recent mboards!
In the worst casesof ram incompatibilty, your mboard WILL NOT BOOT when any incompatible module is installed, and it may not beep at all!
It is easy to test for incompatible ram that has caused your mboard to fail to boot.
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 or owner's 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.
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:
A 1000 watt PS will handle any current possible system, even one with 3 or 4? PCI-E X16 video cards.
If there is nothing wrong with your power supply (you haven't un-intentionally fried it) it should work fine connected to a known working desktop system.
A known working PS from another desktop computer that has all the wiring connections you need should work fine with your mboard if nothing else is wrong - but it would probably have to have 400 watts or more capacity, and you may need to unplug the second video card in a slot .
