New Components; System Turns on but No Post 1

[stevenriz]

Hi everyone. I just purchased the following components and cannot get a post. Tried different RAM and don't know what to try other then getting new components. I mainly picked these items because Newegg suggested them and that they were compatible. I tried one ram stick, then the other, then another that I had at the house. Nothing. I tried moving the HDD, PWR, RESET connectors around, nothing. I know the colored connector is + and the whites are -

The system turns on, I get the power LED and holding the power down, it shuts down. I get no video.

Only possibly bad parts are the mobo and/or the CPU. I've built about 30 machines without problems from newegg but am wondering what I might try to get any sort of screen or beep.

Here are the components I purchased.

- ASUS P5KPL-CM LGA 775 Intel G31 Micro ATX Intel Motherboard
- Intel Pentium E6300 Wolfdale 2.8GHz LGA 775 65W Dual-Core Processor Model BX80571E6300
- G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK

First Can you check to see if you have the correct BIOS to support these new components?

If you can be sure of a correct BIOS then I would try the following:

Of the three new components you can you try to eliminate the troubled or incompatible one by replacing it with an original component one by one and testing POST at each swap?

I would probably start with the RAM (easiest)also because it should sound "beep" patterns if the ram isn't compatible, the beep patterns (of long and short beeps)can offer clues about bad memory sticks.

Wish I could offer a better or easier solution.

Good Luck

Next swap the processor etc., noting that it may take a while to determine a bad or incompatible component (more than one combo)

Some motherboards are shipped with the CMOS clear jumper set in order to save battery life and this keeps the system from running.

If you're getting no beeps at all, it sounds like the CPU isn't even starting up. I'll assume at this point that the PSU is a known good one, and that you have the full 24-pin connector to the motherboard, plus the addition 4-pin one. I will also assume that you have no other devices connected to the board at this time.

Remove all components from the motherboard, remove the battery, short the CLR CMOS jumper pins and also short out the battery terminals. Move back the CLR CMOS jumper, replace battery, recheck the motherboard CPU connector pins for damage, replace CPU, RAM etc.

If all other jumpers are in their default positions and you've verified the RAM is ok, then the fault is probably more likely to be with the motherboard...

to throw in my 2 cents worth...

some mainboards need the CMOS reset to recognize new CPU's, also it is possible (as mentioned) that the BIOS just does not recognize the CPU (an updated BIOS could alleviate that)...

Remove the board from the case plug in video card (unless it has onboard video)plug in one stick of memory and power to pwr supply, short the pins see if it posts.

 

[stevenriz]

thanks for the help. I have the mobo out and only the video, cpu and 1 sick of ram plugged in. No results. I ordered another mobo and cpu thinking I should figure it out with that. Then I'll have whatever bad component replaced. Then I'll have spare parts for a new machine or replacements....

 

[firewolfrl]

hmmm! first check the motherboard to see if the case speaker is plugged in then check the case to see if it even has a speaker. (this is common)
if you pull all the ram and boot it should give you continuos beeps
use one stick of ram and try to boot
remove video card you should get some beeps (this is if its not onboard)
reinstall video card and make sure it sits snug

if you have no beeps at all on any of those:
did you match the cpu to the motherboard?

call the MB manufacturer and have them walk you through the setup...they are usually pretty good about that


good luck

 

[stevenriz]

ya I spoke with ASUS the other night and we plugged in the speaker and go no beeps no matter what we did. He blamed the CPU but my gut tells me it is the mobo itself. I will report back what I find when I get the new parts tomorrow.

[firewolfrl]

that is why I don't buy Asus mb's anymore. I have had some issues that with a bios upgrade for a new cpu it was handicapped...

but yes that is the first thing they always say when their mb's fails.
ugh!
they have a tendancy to blame everything else and waist your time
to me, dealing with Asus is like dealing with microsoft

I now use Foxconn mb's the tech support is awesome with those boards and stability is rock solid

 

[stevenriz]

I may take your advice firewolfrl... I have always uses asus. I can't knock their tech support, the guy really seemed to want to help. We cross checked the bios level at ship time to the CPU to the RAM to be sure everything was in the compatibility list and it was... This would not be the second board that has been delivered bad if in fact this one is bad. We'll see....

 

[firewolfrl]

here ya go

for the foxconn mb's

If it's the mobo, I wouldn't say it's an Asus problem. I'd say it's just a lemon mobo. I don't know of a single manufacturer who hasn't had some lemons. If any one person got a handful from one manufacturer, that doesn't mean that it's a bad manufacturer.

As for tech support, some are great, but not necessarily all. And with that, you can't totally judge a company by the tech support you get on the phone. Nowadays, manufacturers have to operate on shoe-string budgets in order to remain competitive. And of course, you get what you pay for.

What do you have the ram running at? is it defaulted to a lower speed? or have you manually set it to 1066mhz?
The only reason I mention this is it will need over volting to run at it's design speed.
I would be tempted to try a stick of plain 800mhz stuff.

[stevenriz]

Well Gentlemen, we were all wrong. I won't keep you in suspense. The power supply was no good. I purchased a second mobo and cpu identical to the initial ones I purchased and first put the old CPU on the new mobo because my gut told me it was the mobo. Well still the computer didn't post. It turned on ok but didn't post. Well I tried every combination of mobo, cpu and memory and still nothing. I looked around my bench and saw a new PS and thought I'd try it for the hell of it. It booted. As Firewolf was moving mobo brands, I may move PS brands. It was a Raidmax PS that was part of a case/PS combo. I've purchased these cases before and never had a PS issue.

thanks for all the suggestions and help. Sorry it wasn't anything we thought though

 

[kjv1611]

Yeah, Raidmax isn't exactly high-end in PSUs, I'd say.

Well, I'm shocked none of us already mentioned the PSU. Glad you got it sorted out, for sure. Too bad you had to go through so much over a bad PSU. Sometimes those are difficult to diagnose without flat replacing them.

[firewolfrl]

OMG, it is ok to have a brainfart

I have had psu's go bad before too...sometimes its hard to do hardware diagnostic on just what someone posts


glad to hear its working

 

[G0AOZ]

Glad you've sorted it Stevenriz... I did actually mention earlier, "I'll assume at this point that the PSU is a known good one...", but I'll be the first to admit I sometimes miss the obvious!

[stevenriz]

total oversight on my part Roger. I read it and printed this post out while working at my bench and read down the list. I figured since the PC powered up, the PS was fine. Obviously NOT. Maybe not enough power to the CPU??

 

[mscallisto]

Well I'll give GOAOZ a star for at least thinking of the correct answer ... and glad you hear you're up and running stevenriz, thanks for the final update.
