Windows 7: Windows 7 Ultimate x64 regular freezes

Hi,
I did a clean install of Windows 7 Ultimate x64 on my custom built machine. Installation went through fine, but when I log in, the system freezes every now and then. I tried getting a minidump, but nothing is created (like a C:\Windows\Minidump). Here are other things I have tried -
1) Safe boot - works fine - no freezes for a long time
2) Safe boot with networking - works fine - same as above
3) BIOS, Video card driver (GeForce 8400 GTS), motherboard chipset driver - all updated
4) Re-seated Ram (1 GB on 2 separate sticks) in different slots
5) Clean boot - disabled nVidia driver, which was the only non-MS driver - this time started getting Freezes randomly. Freeze happens while browsing a website, playing a game or even when left running idle (without any applications running).
6) Ran a memtest last night - did not report any errors.



I am out of ideas. Any help will be appreciated!!!

System specs:
FoxConn 975XAB motherboard
Intel Core 2 Duo processor (I think it is the 6800)
BFG GeForce 8400 GTS Video Card
Corsair 1 GB RAM (2 x 512 MB )
WD Harddrive - 640 GB SATA
WD Hardrive Caviar Black - 1 TB SATA II

Thanks!

The minimum requirments for 64bit is 2GB of ram,i think your problem lies therein.

I can't believe I missed that simple spec! Sorry to waste your time.

Thanks for pointing it out though.

It might not be the sole problem,try using the 32bit version and see if it will work ok,if it does then you can guess that the 64bit is the issue at hand or at least the lack of 64bit drivers

Still facing the same problems . I added 2 GB of RAM and tried running IE8 - everything froze. I had resource manager on and it didn't register anything more than 760 MB of memory usage. That is probably not absolutely accurate in terms of memory usage, but probably also gives a decent picture.

I have since then, tried clean boot with disabling of half the MS drivers as well as the only non-MS driver and have had no success.

Any ideas would be greatly appreciated!

One thing I noticed is that the fan sitting on top of the chipset is not working anymore. The temp's reported in the BIOS settings seems to indicate everything is fine, but this might be an issue. I will replace that fan and see if that helps.

1) Verify your temps for your graphic card.
2) have you upgraded recents graphics drivers ? If yes, then try reverting back to more stable one. (specially if you have an nvidia card)
3) Try having only 2 dimm used in memory slots. Try have the dimm to be the same size and the same manufacturers.

Just some quick advice I can think about...I do not know if this can give result, but it cost nothing to try !

Great pointers. I will try these. I do have 2x512 in 2 slots and 2x1GB in the 2 other corresponding slots. I will try removing the older ones. Also, I did update the nVIDIA drivers to the latest ones for the GeForce 8400 GTS card. I have tried clean booting without that driver loaded and it still locked up.

How do I check temps on the graphics cards?

I tried re-installing Windows 7 and now it won't go past "Windows Starting Up" - more problems!!!

I will keep trying...

To check your CPU temps id would use techPowerUp! :: Download TechPowerUp GPU-Z v0.3.8


Try running start up repair ,tutorial here
Startup Repair
Try it three times if the first two do not get it.

If that fails,seeing as it may be your GFX card,Go to Nvidia,get the leatest stable drivers (no beta ones) and load them to a usb or a CD.

On the Install part of the Windows 7 Installation disc click advanced>load drivers and load the gaphics drivers manually.

And if that gets it going,can you check your device manager (control panel> (small icon view) device manager) and check for any yellow triangle's.
If so,can you post a screenshot.

If it works in safe boot it is probably not memory. While less things are loaded at safe boot and hence you would have more memory available I would look elsewhere

A good place to start is in event viewer (type eventvwr in search). go to the windoes log>application tab. Look for errors (errors have red in the left hand column) that say app hang, app crash, etc.

when you find them use the snipping tool (type snippiing in search) to make a screen shot and upload it to us using the attachment icon (shaped like a paper clip) in the reply form.
