Windows 7 won't boot past the loading screen

[Madog]

Hi,

My problem is that windows 7 wont get past the loading screen when its loading the OS. I have noticed that it will work when i have only 2GB(one stick) in but when i try to put all 8GB(4 sticks) in, it wont work. This same thing happened when i was trying to install windows 7 from a fresh install.

I would really like to get this problem solved, so if anyone has some advice. Please let me know.

Please & Thank You,
Vince

Hello there, Madog Welcome to the Se7enforums!

You would think that little over 2gb-3gb problem seen with the 64bit Vista would have been solved for 7 which for most it has. I run the 64bit 7 RC with 4gb without a glitch! With the larger number of dimms however you may have run into some bad memory which would be a cause to consider since the 64bit 7 supports a larger amount of ram over that seen with the 64bit predacessor.

One fast way to at least isolate the one or more bad dimms if that's the case would be trying the other two you removed without the working pair in. If you mixed pairs of dimms by a different brand seeing a different timings that will cause problems.

I put each stick in one at a time and they all worked. Then i started putting two sticks in at a time and it worked. Then when i put three sticks in(6GB) it wouldn't go past the loading screen. The animation wouldn't come up or sometimes it would come up but then hang.

When people were seeing all these problems with Vista the MS advice was to removed all but 2gb until Windows was on and running good. Then you would add the other dimms back in for the larger total on the 64bit editions there. But you already have 7 on which is the item there.

Did you buy all of the dimms at the same time or buy one pair separate from the other? You may have ended up with a mislabeled dimm if none are fould to be defective which is one reason why a good run of memtest or another good memory stress tester for each dimm would be a good idea there.

If one of the 3 you just tried is a different type like a mix of 2 perfomance dimms with a standard module that will cause problems. One idea would be taking the 4th dimm and swapping out each of the others one at a time to see if you see results without a particular dimm present. It's a bit of work but would isolate a problem dimm.

I bought them as a set. They are the Geil Black Dragon Series, running at 800 Mhz at 2V. They all worked just fine when i was running Windows Vista Ultimate 64-Bit and with XP Pro 64-Bit.

When you first installed the previous two 64bit editions of Windows how long ago was that? A dimm can develop faults after a period of time since memory is one hardware stressed a lot along with the cpu.

The other question that comes to mind first however would be the method you are using to install 7 may have a problem where it's not memory but OS related from a possible bad install. You would see that if there's a problem with the dvd or usb key used for example even if the iso is intact.

 

[Madog]

The Xp was over a year ago and the Vista was last saturday. The RAM is only 6 months old.

The problem happens with a DVD and a usb key. Guess i could try to get my hands on another ISO and see if that works.

btw, thank you for all the help.

Hope that all it will turn out to be there. You run into a few frisbees once in awhile surprizingly with any brand blank media if you don't have a glitch with the program used or the iso itself.

I've been running both the 32bit and 64bit beta builds then RCs later with the 4gb here where only one of the 3 OS drives is best used for storage only due to problems seen with the programs installed regardless of which build was on! Hope to hear some good news from you later!

This can also have to do with the memory settings used. With 8GB it's easy to create a voltage short fall. Win 7 seems a bit more demanding in certain areas involving memory settings. I would shore up the chipset voltages in bios to fix this problem. I've seen it work a million times with 8GB already.

 

[Madog]

Im gonna get another copy tonight. I will post back when i have installed or tried to install the new copy with all 4 sticks in.

I already tried the voltage settings. I bumped up the voltage on the NB and RAM.

How are you burning the DVD ? Best bet is 4x with Free ImgBurn software program.

@Night Hawk-

Hey you said you were running your Windows 7 RC with 4GB RAM without a glitch!!
Ive been trying to get mine to show more than 2.5GB of usable memory that Windows says i have. it shows the 4GB but it won't use them all for some reason..any help is appreciated..oh im running Windows 7 x64 build7600..

 

[Night Hawk]

Slow down a bit migRas By the way welcome to the Se7enforums! since no one did that on the other thread you came in on at http://www.sevenforums.com/graphic-...ver-installation-issues-driving-me-crazy.html

Rather then hijacking this one somewhat you might want to start a new one on this since it's a totally different problem in the Hardware + Devices section. Right now we're trying to get Madog's situation resolved here in Installation + Setup. Start a new one there guy. Then you will even get more ideas on that problem there!

 

[migRas]

sounds like a great idea Thanks!!!

test the RAM. Memtest86 is a great FREE tool you can get here.

second, when all of the DIMM slots are occupied, many motherboards will undervolt the RAM, as most people/users will only be using two modules, this is usually not an issue. check the voltages in your BIOS, and if there is any instability, up the voltage a lil. find your RAM's specs from the manufacturer to make sure your motherboard is providing adequate voltage, and the current does not fluctuate.

using 2 sets of 4gb (one PNY and one Mushkin) for 8gb in my system took a little tinkering to get stable, and i had to up my voltages to 1.65v which is well within the tolerance for my RAM (up to 1.8v is upper limit of my modules).

if your RAM passes MemTest, then I would suspect the voltage needs to upped to allow boot to desktop, and grant stability. if your RAM fails, then RMA or return to vendor for replacement, depending on your options.

also check that RAM is set in your BIOS to be running as the manufacturer lists for your RAM. most of the time auto-detect works, but manually setting to the manufacturers spec's is another option.
