Just build my first computer from parts. Great experience mostly, but I'm having a minor, but annoying problem. Computer specs at end.
The computer has to have its CMOS reset before every cold boot. If it isn't reset, the power comes on, the DVD drive keeps trying to spin up with no disk inserted, and I never see a monitor output.
If the CMOS is reset, it POSTs fine, prompts me for the system time, and otherwise behaves normally. Restarting (warm reboot) the computer works just fine, but even with no other changes to the bios, it will not cold boot.
For what its worth, I'm also experiencing 1-2 minute boot times on a system I hoped I designed for 15-30 sec boot times. Not sure if this problem is related.
Well ... pull the data ribbon off the dvd drive and boot a few times ...
... could be a flakey bios/mobo ... you will HAVE to do a breadboard build, to prove/isolate the fault.
This chklist will provide a methodical roadmap, to gain progress and not just "bounce" around the problem.
To "reseat" means to "pull ALL the way out" and ONLY then, to re-insert FULLY.
You CAN work/TS with only ONE stick of RAM (and rotate those sticks) ... (READ!).
REMEMBER! ... You can't just skim the chklist and say "did this .. did that" ... You MUST perform or absolutely verify each step, or it is useless. DO NOT assume that you are too smart to have mis-placed a mobo standoff, for instance ... ASSUME that you are exactly that inept ... or ... may never solve.
We are here to consult and to clarify ... talk to us ... strip it all the way down ... OUT of the case ... NO mobo cables (wires) AT ALL ... just PSU/mobo/spkr/one-stick-ram. ... build/swap/rotate/test/log .. REPEAT with next component.
It hurts ... but, with such issues, even the PSU (marginal or dirty power) can be the prob ... bad bios .. bad stick of ram .. bad ram slot .. squirelly anything.
Here's the DOC ... it is HIGHLY EVOLVED (many revs) ... does work (*IF*).
The obvious cause of this problem which I am sure that you have checked is that of a faulty CMOS battery. If this is not the cause of your problem then the motherboard is probably faulty although a faulty power supply could cause this problem.
Appendix A. POST Codes for the EVGA
This section provides the AMI POST Codes (Table 6) for the EVGA H55 Motherboard during system boot up.
The POST Codes are displayed on the Debug LED readout located directly onboard the motherboard. This Debug LED will also display current CPU temperatures after the system has fully booted into the Operating System.
