Question

Computer won't start with new video card

Sep 27, 2013 8:46PM PDT

Hello all,
I recently bought a new video card, the Asus Nvidia GeForce GT 640 2GB DDR3, but when I replaced it with my old video card, which I believe is a Asus Ati Radeon x1300/x1550 Series. That one worked fine until it started messing up my games, the screen was all broken up, a lot of noise. Eventually it would even crash when I started iTunes simulation. Anyway, I needed a new video card, but once I got it, my computer wouldn't even start. Normally, it start with a little 'beep', but that doesn't happen with my new card. It apparently prevents my computer from starting. When I wanted to post this message, I restarted my computer to check which motherboard I have, which is the P5VD2-MX SE Motherboard X Series. However, my computer wouldn't restart after that, whether with my old video card, the new one or without a card at all. I was wondering if anyone knows (where to find) if my motherboard is compatible with my video card or what else to do.

Thanks Happy
Vasilis

Compatible?
Sep 27, 2013 10:40PM PDT

Aren't the cards not fitting in the required slot and further you should have checked prior to purchase that question. I mention that only to say if it wasn't compatible then it wouldn't fit more than likely.

Next, you really need to rethink this, because, you already had a problem prior to the new video card. Check the specs of each card, google for that and then compare them. What you may find is the basic power requirements for each is different and more important even if you have the required PSU wattage, etc., it always pays to have more, lots more and be stable. That said, make sure all connections are done and proper and if you're still using the old PSU that isn't the crux of your problem. If the old video started to fail because it taxed the old PSU and prolong game play didn't stress it and the video card from heat build-up. Heat build-up degrades the PSU and any electronics to become less capable if not build well or matching needs. Check all that and decide what now is needed. As a side note, your new video card *may have* been the last straw, it blew the PSU in some way since it may need more than its capable of sustaining.

Well...
Sep 28, 2013 12:38AM PDT

The card does fit the slot, there's no problem with that.
The power supply also won't be the problem, I believe the card needs 75W, while my power supply has 350W. Everything that needs to be connected is connected, in the video card manual it states you do not need extra power supplies for it to work, you just put it in place and fix it with a screw. I think my old video card started to fail, just because it was spent, although the cooling unit does get quite warm.
The computer itself is perfectly fine, as Linux system running from a cd (dvd?) works OK.

Assuming the GPU is fully seated in the PCIe slot
Sep 27, 2013 10:48PM PDT

and power is connected to the GPU...my guess is the power supply (PSU) is insufficient for the system with the new card.

Question is, did you connect power to the GPU and what power supply do you have ?

My PSU
Sep 28, 2013 12:54AM PDT

If the card would get no power, my guess is the system wouldn't recognize that it's there at all and it should just start as if there is no GPU at all. Anyway the fan works when I (try to) start the system.

It's not a very clear picture, if you want me to I can take a better one.

PS...you MB is compatible with that GPU.
Sep 27, 2013 10:59PM PDT

Another question ....did you look at the motherboard capacitors ? Believe you MB was manufactured during the period when substandard capacitors were used. If you do a search on 'bad caps' you'll find PICs of what bad capacitors look like. If your MB has bad caps ... you'll just have to replace it or get a new system.

Bad caps
Sep 28, 2013 1:06AM PDT

I can't find when my motherboard was released, and I don't know too much about bad capacitors. Anyway, why would these 'bad caps' mean that my motherboard doesn't work with a particular video card?

- Collapse -
We can discuss why that is but.
Sep 28, 2013 1:17AM PDT

But we would be circling around a well discussed issue rather than getting this all to work.

Pictures and what to look for are all over the internet so type BAD CAPS and catch up on this plague.

Then do the inspection and if they are good, we can move on to what else it can be.

PLEASE DO THIS.

-> I read this thread and can't find what power supply is in this PC. HOWEVER any PC that had an ATI 1300 is likely to have an old tired power supply that is not up to powering the GT 640.

http://www.google.com/imgres?imgurl=http://www.overclock.net/content/type/61/id/908257/width/450/height/432&imgrefurl=http://www.overclock.net/t/1267128/evga-gt-640/20&h=432&w=450&sz=13&tbnid=_hAHHvRWKIMk2M:&tbnh=90&tbnw=94&zoom=1&usg=__WEHBnQ1TZfyTb3DiG5dVTM32NbI=&docid=330vdEdwu_UNjM&sa=X&ei=PfJGUpGPEuSdyQGM4oCQBA&ved=0CGQQ9QEwCQ

Shows the card is about 140 Watts on its own and the ATI 1300 was less so it could be a simple power issue.

Add more detail please.

Bad caps
Sep 28, 2013 1:30AM PDT

I'm not sure that is my card. Even if it is and it uses 140 watts, my PSU is still 350 watts.
I'll look into bad caps more then.

350 is unlikely to be up to the task.
Sep 28, 2013 2:08AM PDT

It's a shame that the make and model was not revealed. Yes that may not be your card but a GT 640 won't vary enough to make this not apply.

Don't take this wrong but why did you omit the needed information when asked? (PSU Make/Model.)

I use that to go check how many Amperes are available and see if it's up to the task. However I see a lot of folk want to discuss technical areas like this but won't supply the detail. I'm always keen to learn why folk omit this information. You don't have to answer but it's always good to know.

Need a little more detail on the GPU...looks like there are
Sep 28, 2013 3:07AM PDT

several ASUS models with GT 640.

re that MB....believe it's an oldie. Bad Caps may not be the problem but always worth checking closely when the system is running erratically, inconsistently and sometimes, not at all. My daughter had an ASUS MB with bad caps and it ran exactly as described above.

Also re the GPU ... it just may be the case the whole system and all components including the new GPU just isn't enough power.

Bad caps
Sep 28, 2013 1:42AM PDT

Well I checked for bad caps and I think I can say fairly certain that that's not the problem. Anyway, the motherboard seems to be fine, considering I can run Linux from a cd on the pc.

Checkout
Sep 28, 2013 2:12AM PDT

It you run Linux live version from the CD, then its loading its own driver for the video card. that usually is a basic driver to cover different video sources out there. Since, you try to load under Windoze then it isn't seeing or hasn't found the driver it wants. If you haven't totally de-installed the old video driver, then do so under the "safe mode w/networking selected" and see if it can do that. If it can, then de-stall and then install the new card's video install s/w, etc.. Once done, reboot and check results. If it still can't boot-up(allow it plenty of time) because switching on video is practically the 1st real test of the boot cycle. My PC remains blank for some time before it displays anything. However, you say it doesn't even boot-up with the old video card, so you see why us posters refer back to the PSU as a possible issue. Also, its very common to have fans running when booting-up and still no display, because that a sure sign of bad or poor PSU. Sorry, I would have swapped the PSU out just to cover that side of things. I find it rather confusing that it boots under Linux and not Windoze and only drivers and power would defeat that.

Startup
Sep 28, 2013 2:39AM PDT

Well, the reason I tried Linux is to check whether the rest of the hardware works fine, which is apparently the case. Something I forgot to mention: I had read something about pressing the pause key during startup to pause that to be able to copy down what motherboard you have. I don't see how pressing that key would mess up my entire OS, but still...
The remark about the fans was to say that it does get its energy.
I don't see how I can go to safe mode when my pc doesn't even boot.
I didn't uninstall the old drivers, but my computer wouldn't let me install the drivers of my new video card, because it said it couldn't find the card or something (obviously, it wasn't there). According to the manual, you should first install the card and then the drivers, not the other way around anyway.

PSU supplies various voltages plus amps
Sep 29, 2013 2:30AM PDT

PSU is the source of all the voltages and the amps to drive them. Fans running only means at least the 12V is present. The next step is to check with a multimeter the status of the other voltages. Even if present, they may not have the amps to drive the devices attached, this is important to understand. Which is why rather that 2nd guessing the posters, simply try fixes and check results. At least you have further clues to resolve overall the issues, sorry but that's the way it is. No magic here, just go down the list until it works or remove the possible problems present.

That (old?) PSU with the 20A +12V
Sep 28, 2013 3:13AM PDT

As you know you halve the 20A for a few reasons which I'll skip here because that's in prior discussions.

The new card is well over 10A and even the current at switch on time looks to be more than an ATI 1300.

-> Beg borrow steal any single rail 500+ Watt PSU for a test.

Again.
Sep 28, 2013 3:22AM PDT

Unless you supply a link (details are important) I'm going to go with the usual GT 640 needs. Also I'm going with a rule about PCs we build in that we never go over 50% capacity of the PSU. There's a lot of web pages at Tomshardware about power supplies and how they rarely can run at the rated capacity so we know to take the rating and halve that.

This is a lot of posts and if it goes much longer I wonder if it would be better to let a shop fix this one.

I'm not sure, because my computer told me the one thing, it said something similar but not the same on the video card and I can't find a picture that is exactly the same as mine. Most have a fan, while mine only has a cooling unit.

This one seems alike my PSU, although mine has an on/off switch and space for an extra cable to supply my screen with energy:

Great info. One other item.
Sep 28, 2013 3:48AM PDT

We know we halve the PSU for a few reasons. Another is age. My last ATI 1300 was about 10 years ago so the age of the PSU could be quite old. And since Electrolytic Caps do age we need to know the PSU's age to see if we could push it.

Even if the PSU was new, it's pushing the PSU too hard in my opinion. To figure this out I'd be popping in a 500+ Watt single rail unit for a test run.

If you have two PSU
Sep 28, 2013 11:39AM PDT

Use them both to see if the problem is power related. Take off side of computer, use the second PSU to power just the video card alone. If all runs well, then you know the solution. If your tower has room enough use some double sided tape and secure the second PSU to the bottom, adjust for added case cooling, such as turning tower on side with mobo to the downside, which allows heat to better dissipate instead of concentrating just at the top where the other PSU likely is (some are already at bottom of case). If the side has fan mounts, then have those blow outward/upward.

Not sure but don't think that GPU has any external power
Sep 30, 2013 9:53AM PDT

connectors...least I couldn't see/find any. That's one of the reasons I asked the poster to give us the full product number....just to make sure I was looking a the right product.

Now that we know the card works in another PC... be nice to see if it would work with a more robust PSU.

Oct 1, 2013 2:09AM PDT

At 75 Watts it went over the 60 I found and then we are talking about a very old motherboard.

This may be one of the rare video card and motherboard compatibility issues HOWEVER they have yet to pop in a monster PSU to rule that out.

Found something about the PCIe power limitations.
Sep 28, 2013 4:07AM PDT

"PCI-E 1.0 is 60w.

A standard height x16 add-in card intended for graphics
applications must, at initial power-up, not exceed 25 W of power dissipation, until
configured as a high power device, at which time it must not exceed 60 W of power
dissipation.


Devices draw power from 12v and 3.3v, and cannot exceed 75w between the two."

This seems to be true for PCIe 2.0 as well and given the age of the motherboard and that this card appears to tap only the PCIe slot for power you may have an issue.

ASUS might be best asked if this video card is compatible with this motherboard.

So...
Sep 28, 2013 5:28PM PDT

So what does that mean? That they say it doesn't need extra power supply but actually does? And my initial question here was if anyone knows where to find whether my new video card is compatible with my motherboard. So I should ask ASUS about that?

I looked at this because the card takes power from said slot
Sep 28, 2013 9:34PM PDT

So I wanted to see if there could be an issue there and sure enough it looks like it can.

Keep in mind you are mixing a 2013 video card with what looks to be a 2006 motherboard. There may be an issue like this or something else.

--> HOWEVER ALL THESE POSTS and I can't find if these card works in another PC.

And I'm not sure if the PSU has been changed out.

-> Yes, Yes I hear you. It should work but it does not and therefore you get to do what we do at the office.
