Windows 7 Bluescreen 0x00000124


Nov 2, 2008
Hi, I'm using Win7 x64 RC, and every time I try to watch a streaming video in fullscreen (doesnt matter which browser) a bluescreen appears. There's written STOP: 0x00000124 and that there was an uncorrectable hardware error. I have tested my ram with memtest86, without errors. I have read in a german forum that disabling C1E and SpeedStep could help, so I've tried it, but it didnt work.

When I reboot windows a window opens with the problem details:

BCCode: 124
BCP1: 0000000000000004
BCP2: FFFFFA80023EE038
BCP3: 0000000000000000
BCP4: 0000000000000000
OS Version: 6_1_7100
Service Pack: 0_0
Product: 256_1

Does someone know how to solve this problem?

My system:
Windows 7 x64 RC
Core2Duo 6400 @2.13 GHz
ATI HD3850 512 MB
2*2 GB DDR2-800 Kingston ram (2.94 GB usable because of the old mainboard, I'll get a new one next week)
Asus P5VD2-X
My only opinion is possible motherboard problems. I started seeing BSOD's similar to yours just before my motherboard totally quit. Turns out my large obtrusive northbridge heatsink came loose and the northbridge overheated. So even if it's not your issue, I would check all heatsinks and motherboard fans for anything loose or otherwise.
Do you have any add-in cards, such as PCI wireless or modems, etc. Try removing any extra add in cards(keep the video card, if you have one in there) and then do what you normally do and see if the error comes up again.
I had a 5.1 soundcard and a pci usb controller which didnt work. I've removed both and i also tried without any external usb hardware, but it didnt change anything :frown:

EDIT: Got my new mainboard, and now there are no more bluescreens :-D
