Lenovo - H520 Not Turning On With New VGA / RAM

I bought this computer :

Lenovo - Desktop - 6GB Memory - 1TB Hard Drive

Model: H520 - 57317327

But I installed a new PCI E video card - 2GB , DDR3 PC3-10666 (2 sticks of 4GB) RAM , and a VGA Cooler fan.

When I went to turn on computer , it just beeped non stop .. until I turned it off.

I tried different power outlet , same problem.

Removed all new items , went back to how it came from store .. and it came on fine.

Any ideas?

Try installing the memory or video card first, then powering it on to make sure that part works. Then remove that part, put in the other new one to ensure that works by itself.  Then when you are sure that they work individually, put hem in together. Make sure that everything is seated properly too.

I did notice that the VGA Card requires minimum of 300W power supply.  The one my PC has is 260W.

Also , I tried the new RAM alone .. and still made beep when it turned on.

Another thing , when I first bought the PC .. it made the same beep - so I took in to store , thinking I got a bad one.  But , when they tested it , it turned on ok.  So I brought it back , tried on a different outlet and it worked.

Could it be the surge protector I have might be going bad?

Which graphics card are you adding? Does it require external power (i.e. not just from the motherboard slot)?

The powersupply can certainly be an issue. Get one that has more wattage. As has been mentioend above, try everything individually first. Also make sure that if your new video card has an additional power input that you connect the powersupply to it. This often gets forgotten (has happened to me more than once, as I'm not used to using video cards with such an additional power input).

Anotherthing to check is that your new RAM is supported by the mainboard. For most boards you get a list of what CPU and RAM models are supported. Sometimes a BIOS upgrade can also add support for new models of CPU's and RAM.

That Lenovo desktop may only work with specific versions of memory and the VGA adaptor. I've see this before when upgrading laptops and desktops before.

Here are the specs I found on that unit:

You might try contacting Lenovo support to see if they can suggest the proper memory and VGA to use in that unit.

Also go to a few sites and see if they have memory for you. I've purchased memory from both of those sites and they guarantee it will work. If not, they refund your money.

I suspect the issue is one of two things:

(a)  You're drawing too much power from the PSU ... you're using a video card that is somewhat over the rated specs of your power supply AND at the same time you've bumped up the power needed for your installed memory.   That combination may be too much.


(b)  Does your video card require a PCIe auxiliary power connector?   If so, you may simply need to plug in that connection (if your PSU has one).

website above says :
Memory Specification Compliance PC3-10600

The RAM I bought is = PC3 10666
(says compatible with 1333MHz)

Thanks all...

Found that culprit was RAM -

computer now running ok with new VGA card and VGA card cooler.
