I have Win 7 32 bit build 6.1.7100. I have installed all the updates from windows update except for all the language packs. I have all the drivers I could find for Windows 7, including ATI Catalyst for graphics. I could not find most of the drivers for my Mobo,k but everything seems to be working just fine. My guess is that Win7 already has generic drivers for this mobo. XP did not have the drivers. System: Motherboard: Gigabyte GA MA770 - UD3 CPU: AMD Phenom 9600 Agena (Black Edition) 2.3G RAM: 4G GSkill 1066 GPU: ATI Radeon HD4650 1024MB PSU: Demon 580w Black Chrome HDD: WDC WD1600JS-22MHB0 Serial ATA Now, for the problem(s). When I installed Windows 7, I couldn't do it from a my DVD with the ISO burned onto it. So I researched and learned how to do it from my USB drive. Now my DVD optical drive won't read very many cd's or DVD's, although it will read some. The biggest problem is BSOD's. At first, I got a couple while installing drivers, but I restarted, uninstalled the driver that caused the crash, then reinstalled and everything worked fine. After playing around with the features, I wanted to see how it handled games, so I installed COD4. I can play for about 20 mins, but then comes the BSOD. When I restart, I can play for about an hour, but then another BSOD comes. I am not OCing in any way, so that's not a problem. I am posting all the information I can about this problem, so any help will be appreciated. When recovering from a crash, this is the report Windows gives: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7188.8.131.52.256.1 Locale ID: 1033 Additional information about the problem: BCCode: 124 BCP1: 00000000 BCP2: 85A7C01C BCP3: F6002000 BCP4: 28000135 OS Version: 6_1_7100 Service Pack: 0_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\062609-16754-01.dmp C:\Users\Mike\AppData\Local\Temp\WER-30872-0.sysdata.xml Read our privacy statement online: Windows 7 Pre-Release (Release Candidate) Privacy Statement Highlights If the online privacy statement is not available, please read our privacy statement offline: C:\Windows\system32\en-US\erofflps.txt I am also attaching the minidump file of the most recent crash.
