Le Sigh

Quaunaut

<div class="IPBDescription">Computer Issues.</div>So my power supply died about 2 weeks ago. I got it RMA'd, got the new one back yesterday.

Hooked it up as best me and my roomie can remember(I put it together the first time, he rewired it for airflow).

Now were getting a No Signal on the monitor.

NOTHING in the computer has changed, other than replacing the power supply with an identical one- for this, I'd think it wouldn't be a BIOS issue(or am I wrong?).

All the fans are working- on the video card, CPU, case fans, etc. I have the video card hooked up by its power cord as well.

All drives are working.


Here is another 'clue': I remember this problem happening the first time I put the PC together, but it was because I didn't put my P2(4 pin) in. Putting it in alleviated the problem. This is not the case this time: Its in.

Any ideas to what could cause this?

Heck, if anyone wants to walk me through(using the shots from those pages) putting everything in, that may even help. I'm up for anything at this point.

Do you mean you replaced the power supply with the exact same model? I know some older boards require the negative 5 volt power rail while the newer 24 pin ones do not. Thus the missing pin on your main ATX connector on newer power supplies. You might want to take a look at that first.

Also does it appear to be booting? Making normal post beeps? Also, does the monitor work on other computers?
Here's an example picture so you know what I'm talking about with the pins on newer supplies. Notice the missing pin by the clip

Its the same exact power supply.

It appears to be booting, its making the appropriate beeps.

It indeed works on another computer.

Kouji_San

Might seem silly this, but did you remember to plugin the 3dcard powercable?

I do appreciate the "painfully obvious" ones, as I've got a gut feeling thats what it is.

The graphics card may have come loose during the fiddling, so that it still gets power, but doesn't work correctly. I don't know if graphics card output nothing at all if they get power but no data, but it's worth a try. You could try removing and reinserting the graphics card if you want to be sure.

Does the computer actually boot? Do you see harddisk activity? If the computer is connected to a network, can you ping it?

TheGuy

Only thing left to try is a different video card then <img src="style_emoticons/<#EMO_DIR#>/sad-fix.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad-fix.gif" />

heh, I thought you ment the AT connector into mainboard. Read it wrong, sry ^_^

I don't have it on a network ><

I believe the Hard Disk is going.

I'm pretty sure its booting.

Kouji_San

Do you have diagnostic lights on your mainboard? If so you could see where it stops the boot sequence if you get you manual. Other mainboards could use a morse code beeping sound, similar to the lights only more annoying <img src="style_emoticons/<#EMO_DIR#>/tounge.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tounge.gif" />

Might also want to reset you bios, just find the jumper which resets the cmos. Should also be in your manual. Make sure you have all powercables disconnected if you do this. If you can't find you cmos reset jumper, you can even remove the bios battery for a minute or so then reinsert it. Next time you start the default settings will be loaded into the cmos if you reset you bios... (overclocking/fatal error backup feature)

With your monitor not showing anything, doesn't actually mean it's 100% related to the 3dcard. I sometimes have trouble with my SATA150 drives on my Abit, and it also doesnt show anything on the monitor when doing that. A similar thing happens when overclocking to far and the cpu or memory can't handle it...

I just have to turn off the PSU for a few seconds until the lights on the mainboard turn off. then everything works fine again. Simple bug in the current bios with sata drives. That and I don't feel like updating, since it's very rare that it happens <img src="style_emoticons/<#EMO_DIR#>/tounge.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tounge.gif" /> With overclocking to far, I do have to manually reset the bios, but thats normal

TheGuy

It wouldn't be the hard drive if you're getting no video signal. You should get a signal before the HDD even boots. (IE with no hard drive you'd get an error saying no OS detected)

Not if the bios settings are corrupted or wrong/overclocked

Xyth

When the power-supply died it might have killed some of your components? If there is no-signal to monitor but everything still turns on but no beeps; then I usually say that either RAM or processor are malfunctioning. Test some of the components in a working computer?

404NotFound

Just start trying to isolate the problem...

Find an old vid card, put it in and see if it works.

Find an old monitor, hook it up. See if it works.

Take out all un-needed components, boot up, see if that helps. (Incase there is some weird conflict)


When the power supply went it could have surged something like the vid card to death.

Quaunaut

I know that there is nothing wrong or faulty with the video card and monitor. And there are no compatability issues. And I'm also 100% sure there is nothing fried.

Edit: Lets say, hypothetically, not a single part is broken. Were talking pure setup errors here(physical ones, not settings related).

Revlic

Then that settles it! Your computer is haunted.

Call Microsoft, i think they can de-demon possess your computer for like 25 bucks over the phone.

Seriously though try rebooting and checking to see your computer's either light codes or beep codes. There's a diagonostic adaptor that they generally send with your motherboard that allows to access to the computer's light codes.

Kouji_San

Have you reset you bios yet? A simple reset (as explained above) could fix this issue. As it sounds very much like a problem which occurs during overclocking. Now you didn't overclock anything, but it could still be related to the bios being corrupted or it just has some faulty settings.

- Emphasis on "could fix it" :/

Yeah, I'm trying to find the spot to reset it, but I'm getting wary as I can't find the mobo's instruction manual, and that means its probably 1,000 miles away...back where I built the PC. ><

Their website sucks, too.

Edit: I've found the product manual off of another site. Now I wonder however, clearing CMOS, how will I access the OS afterwards? Or is it a simple way to config into my BIOS?

<!--coloro:#FF0000--><span style="color:#FF0000"><!--/coloro-->Edit #2: Clearing CMOS helps none, but the beep pattern has changed(and I don't think its booting now, just straight-to-BIOS)<!--colorc--></span><!--/colorc-->

Kouji_San

You got to think of a bios chip like this:

- Default chip with factory settings
- Flash chip, with custom settings. This is a flash chip which needs power to keep it's data stored

By resetting it you would simply erase the data on the Flash chip and copy the date over from the default chip the next time you start the pc. It only contains information of the motherboard. It doesn't do anything to your other hardware.

Another way to reset it would be by temporarly removing battery...

Any more ideas folks? I'm hesitant to get a "professional", as every time I've gotten a professional in the past I suddenly "need a new part" and then when its all said and done, I find out that this new part was in addition to several other steps they did, which I've been told repeatedly fixes the issue. ><

if you're getting a beep pattern on boot look up what it means

I remember having the same problem a while ago... just can't remember how to fix it... duh...

It had something to do with the powerconnectors. Like... try to get a different powersupply and see if that works. Maybe get one of your friends to lend them theirs... Maybe a cable from the PS is just broken?

Depot

Before you disconnected the power supply from the mobo, did you purge it? Failure to do so <i>could</i> blow the caps and result in the symptoms you have. Only solution is a new mobo.

My pattern isn't like any of those.

Its short, slightly-longer, wait a bit, then a short, high pitched one from a different part of the computer. That last one has only happened since resetting CMOS, so I'm guessing its the BIOS display coming up.

The mobo is fine. Of that I'm sure.

My mobo acted fine also Q, after I removed / re-installed my power supply. When it wouldn't boot ( and we're not sure yours is booting) and Windows wouldn't load I took it to the pros.

I'm getting two folks involved now to help out, one of them is a friend of my roomie's who builds custom PCs for a living(and large moolah), and the other(for later) is the mastermind behind DamnLan, and certainly knows his stuff- though that at minimum is a few days down the road.
