Windows 7: BSOD Screen 0x00000124 Help ASAP Please!

Hey please i need some help , Ive recently Bought a New Computer from EBAY and im having problems with it , this only happens when i play games , Example : Crysis 2 and Amnesia Heres the code i get on the Blue screen :

STOP : 0X00000124 (0X0000000000000000 , 0XFFFFFA800838B028 , 0X00000000B620A000 , 0X000000000000135)

Please help the guy who i bought it from says its something to do with the drivers not being installed right or something like that. But on the device manager it says they are installed correctly. ;\



Computer Specs :

8GB RAM
ATI RADEON HD 5670
Windows 7
AMD Phenom X II x4 940 Processor
1TB

0x124 is caused by defective hardware, mostly the RAM or GPU are the culprits
Stop 0x124 - what it means and what to try

Could you tell me exactly which hardware it is or? ;\

Your only way to determine the cause is to do stress tests
RAM - Test with Memtest86+
OCCT (OverClock Checking Tool) 3.0.0 download from Guru3D.com

Correct - a 124 is a Windows crash because the CPU passed on information that the system hit an error that was uncorrectable in hardware. Windows then crashes with a 0x124 bugcheck to halt the system to prevent further damage. Without the .dmp file(s) associated with the bugcheck, we can't tell you anything other than "test your RAM, test your disk(s), and test your CPU". One of them reported an error to the CPU controller, which then passed it on to Windows, which bugchecked with information about that error and wrote it to a .dmp file, if one was created at the time of the crash.

For some reason i cant compress a folder with all the DUMP files in it , It wont let me , any other way i can send them to you?

Copy the Dump files to your desktop then .zip them

I have , but it wont let me zip them... ;\
