My Computer Won't POST

[leadfish]

Hello. I am currently faced with the predicament described in the title of this thread. I shall start by listing the components:

ati 9600xt
amd64 3200+ 754
2x512MB Corsair XMS3200C2
WD 120GB SATA
antec 400W/420W psu (can't remember exactly)
asus k8v se mobo (via K8T800 chipset)
sony 17" cpd-e200 monitor

Now for the story! (grab a coffee and chips for it's long-winded )
--------------------------------------------------------------------
I got home for lunch from work on Friday, ate my double decker ham, cheese and tomato sandwich, then forum-whored until I need to go back to work. Upon ariving home from work, tired and keen for some BF2, I found that my monitor would not come out of "power saving mode". Dejected, I switched it on and off, reset it and switched it on and off at my powerboard to no avail. When I reset my computer, noticed a lack of POST beeps.

Yes, dear reader, no beeps whatsoever. Upon consulting a couple tech-minded mates in my DoD clan, the blame was placed on a potentially dead video card. After switching it with the one in my mates computer it still did not post, although my card worked fine in his computer. I also tested both of my sticks of RAM and they're fine.

Now I am at an impass, with a couple ideas of what may be wrong, but with no capacity to test any of these theories, which are:

• dead AGP slot
• dead HDD (The HDD sounds like it is working though, so who knows?)

So yeah, I am hoping that some of you guys might be able to throw me a bone here and help troubleshoot this for me. I'll be checking regularly, so if I have missed any important details, just reply and ask for them

Thanks for your help in advance.

Carefully look over your motherboard, make sure it's lookin dandy and then try replacing your PSU with your mates and see if that does anything.

You should POST no matter what really. Even if your motherboard is damaged, the POST should actually give you the correct beeps to tell you that. Without an HD it should still POST perfectly. The only thing would be if the motherboard wasn't getting power. Thus would be the result of a PSU problem.

I'll have another look over the motherboard, but my PSU is much more powerful than the one in this computer, because all it needs to do is check email, write essays and play 3d billiards ^_^

It needs to register by clicking the link at the top of the page first. Then it can log in and POST.

...need to know more about your system on power up. Is your CMOS light on (do you have one)? Good. Does your PC fire up (CPU fan, hard drive RPM, etc.)? Good. Does your beeper work?

I have an Asus mobo and when I first got my new video card, the extra power cable wasn't plugged in and I got an odd beep for a POST (and no video). It also came with a separate beeper, which needed to be plugged in manually (not soldered to the board).

you get slaps for that.

I vote motherboard.

That reminds me.
Try reseting your CMOS.

 

[Asus]

Is there a light on your motherboard or the light on the front of the case at all?

I would cut power from your PC for awhile and let it sit. Either flip the On/Off switch on the back of the PowerSupply or just unplug it from the wall. Just testing incase there was a charge built up. Leave it for 20mins or something.

It's most likely the motherboard.

 

[leadfish]

There is a green light on my motherboard that lights up when I flick the I/O switch on my PSU on, and the CPU fan, video card fan, HDD and DVD/CD drives all either start spinning like normal or light up at the front like they're all supposed to.

The beeper on my motherboard works, as I took out the RAM just to see if I would get warning beeps, and I did.

I would try resetting my CMOS, but I can't get into it, and I don't overclock anyway. The only manual settings were for my RAM, and that was in no way pushing it.

 

[Adabiviak]

...there we go. Do you have another video card to try?

 

[leadfish]

Yes, as mentioned in the original post, my card worked in his computer, while my computer didn't do anything when his card it.

Hate to say it, but its looking more and more like a mobo/cpu problem

 

[Beerdude26]

Just start your computer and after half an hour if the HDD is still ice cold, it's dead or the power supply doesn't connect right.

 

[bryanf445]

I vote motherboard.

seconded

thirded. I can only really say if you can try the mobo with another cpu that you know works, although, teh mobo could damage a working cpu. hmm is the mobo still under warrenty?

 

[leadfish]

Well dear readers, I think it's my PSU that has packed up, because I noticed that it's fan does not spin. Must go to work now, but will update after work as I might pick up a cheapy during lunch break for testing.

I thought that I read on here that yuo tested the psu in another pc? Oh well, that would explain how the light on the mobo lights up but it doesn't start. Hmm I would have thought that the psu would have been one of the first things taht you should of tested. Doesn't matter though, at least you now know what the dodgy componant is.

 

[leadfish]

I bought another 400W PSU today and just switched them and started up for the same lack of POSTing. Back to square nfi I'm afraid

If it doesn't post with the new psu then it will probably be either the mobo or the cpu. Its quite tricky to test a mobo as the cpu could be the faulty componant and you may not want to put a perfectly good cpu into a potentially broken motherboard, which could damage it.

 

[Cole]

Did you try reseting the Cmos?

 

[leadfish]

Yes, and that didn't prove anything either, I'm afraid. I'm guessing this may be pointing to a dead mobo again?
