up until friday night my laptop was running fine. I am using an Asus g73jw ROG edition laptop. The only thing i have noticed is when i load games the screen would go white for a brief second while it loaded the game then it would load game and everything was A ok. However Friday night while playing my game in full windowed mode as i always do, the computer crashed and gave me the BSOD with a debugcode_usb_driver error of some sort. I restarted windows normally and it booted up and about 1-2 minutes later it froze. I started it into safe mode with networking and once it booted up about 1-2 minutes later it froze. I booted up into safe mode w/o networking and everything worked fine without freezes or BSOD. I went to device manager and seen a usb driver had a yellow exclamation mark. i uninstalled this and it has not returned since. after Restarting windows normal and safe mode with networking quite a few times after and it still froze everytime. sometimes when i clicked something and sometimes it froze on the welcome screen. i read that network adapters might cause this so i unisntalled my ethernet, braodband, and wireless adapter and restarted windows normally. Though it seemed like it help for a bit the computer still froze. Thinking it might still be a wireless issue i disabled my wireless adapter and plugged in an ethernet cord. I was able to boot safe mode with networking without it freezing at all. So i tried windows normal and instead of it freezing it just took forever to load things. at one point the start menu wouldn't even let me click on things. when i could click on items they just wouldnt load no matter how many times i double clicked them. My cpu runs at about 60-70 and spikes rarely to no higher than 76 max load which its rated to 90-100. i use cpuid monitor for temps and msiafterburner for VGA whicch runs 32 idle and 60 full game mode. I have run my uniblue driverscanner and all drivers are up to date. I have manually downloaded new nvidia and atheros wireless adapter drivers and they don't work. I ran tssdkiller (for rootkits and it was clean0, malware bytes, super anti spyware, reg cleaner, cc cleaner, spybot, and Avast while in safe mode. they found somethings but the one thing found was a virus. I quarantened it immediately did a restart and nothing has changed. i read somewhere avast and firefox can cause alot of freezing. I uninstalled both of them and nothing has changed. Currently everytime i boot in windows normal mode and type in my password. the welcome words come up and then it goes into a blue screen wth just my mouse pointer. It has not moved past this since. Thinking it was hanging on a driver i have enabled the os boot log while starting up from under msconfig boot. Twice while trying to boot safe mode with networking it hung up on amddmk.something? and i restarted but it loads safe mode without networking fine. I have been reading and researching all day everyday since friday night. I have ran sfc scan now, memory diagnostics, memtest86, antivirus that boots from thumb drive, ultimate boot cd, hard drive tests, cpu tests, and just about everything i could tihnk of or find even though i am forgetting some of them now. I have two hard drives both seagte 500 gb. They are partitioned into four drives: C:, D:, F:, and G:. I only use C:" for windows related items, anit virus programs, and anything used to debug windows. F and G are use for torrents, video games, etc... I ran a check disk on D: and it completed without any errors( D i think is my recovery drive). I schedule C: to run on next start up. I restarted my computer and once i seen it start checking i left to go out to eat tonight. I came back 1.5 hours later and it was still on 2% complete. Assuming it froze i restarted comp and canceld the second scheduled scan. I attempted to correct somethings and got some advice from my brother. While talking to my brother we came to an agreement that it is either hardware or software (obviously) he thinks it is most likely driver related because it hangs after the welcome screen. So i restart and press F8 to get into safe mode and it freezes. i can't move the cursor up or down. I restart and get into safe mode where it randomly freezes at some point. i restart again and finally delete my nvideo 460m driver and my wireless adapter again. i restart and try to boot normal mode and it froze on the enter password screen. i rebooted and entered password but it still hung on the blue screen after welcome. Windows He decides i need to create a new profile and give it admin rights. I do this in safe mode without network and restart computer. I click other user when it loads and enter the first two letters of the name and it freezes. i restart and enter name and password for other account and it still hangs at the blue scree after welcome. I have tried many times restore last known configuration, startup in low resolution, disable driver signatures or w/e, system recovery (which never works), system startup repair (nothing), and a few others i can't remember at the moment. currently right now as of 1 hour ago I started a checkdisk for drive C: again and it is at 0 percent complete (6340 of 331008 file records processed). I have run out of ideas. Please help. if there is anything you want to know if i have tried or can try let me know. my full specs are from what i remember: asus g73jw-ROG laptop intel core i7-740qm, 1.73ghz nvidia geforce gtx 460m (clocked but i dont remember exactly to what; nothing outrageous) HDD''s 500gb + 500gb memory 16gb Windows 7 Home premium.
