Hello Everyone, First of all I apologize my first post isn't an introduction or something useful but I really need help bad. Here is all (hopefully) relevant info that may help you guys: Mobo: Asus P6T CPU: Intel Core i7 920 (stock) Ram: 6GB DDR3 1333mhz (xmp profile #2) GPU: Nvidia GTX 260 Internet: Linksys WUSB600N -latest driver- OS: Microsoft Windows 7 Ultimate RC Build 7100 (64-bit) Antivirus: Zonealarm Extreme Security beta 9 System condition: Windows update on and newly updated, antivirus updated and scans run regularly. System was finished in June and there is no dust in my computer. My CPU idles @ 35C and my video card idles @ 42C @ 40% fan speed. *While in safe mode one of those times I manged to get into it fine I ran my anti virus / anti spyware and malwarebytes anti malware and both found 1 infection. Zone Alarm found a high rated trojan and quarantined it and malbyte found 1 thing and deleted it. *My friend who is using Windows Vista is having this same problem all the sudden too. He can't get passed the welcome screen normally or even in safe mode. *I have ran CHKDSK and "Error Checking". *The Hard drive is not failing as I used western digital's data lifeguard diagnostic and it said the HD was fine. *I ran CCleaner to fix the registry. *I have the latest chipset drivers from intel for my motherboard dl'd from asus's website for my OS. *I have the latest Nvidia drivers from Nvidia's website and even uninstalled and reinstalled. -----And my story begins------Coffee Alert------ I have been using windows 7 rc 7100 since June with 0 problems. No blue screens, nothing. Until...(dun dun dunnnn...) 2 days ago. I was using my computer like normal, I was on ebay and playing gta 4 and browsing forums (not all at once!) and all the sudden windows notifys me it needs to install 2 updates (1 patch to the actual release candidate(kb972407) and new network adapter drivers provided by Ralink). As I restart I go to restart I get a blue screen and all I could read before the thing dissapeared really quick was "BCC CODE 135". So I restarted and when I typed in my password my computer hangs at the "Welcome" screen. The blue circle thing spins but nothing happens. I restart again, this time I boot up safe mode. I type in my password , same thing hangs at welcome screen. So then I restart once more and this time I try booting up normally. It works! So I use my computer for a little bit. I restart again, try to login normally again and this time it goes passed welcome and I get the "BLACK SCREEN OF DEATH"!. Which basically was my desktop all black with my cursor being able to move but no reaction from my keyboard (not even sticky keys worked). So I restart once more and go into safe mode this time it actually loads! So I perform a system restore to the 24th. I restart my computer and login normally and it works, then windows decides to re-install those 2 windows updates that caused me those problems in the first place and I am back to square one. So I restart again and boot into safe mode I disable all things from starting up (using msconfig) with windows and in the services section disable "Windows Event Log" and restart. So I login and get to my desktop woo hoo!! I think all is well and upon logging in windows tells me it has another updated for me to install (I am dreading this as the last 2 got me stuck here) but I feel adventurous and install it then I do another restart and I login sucessfully!(making this the2nd time in a row since problems started). I think I finally got it and to make sure I restart. So I login normally and it hangs at the welcome screen and I dont even get the black screen of death. I restart once more and try safemode and it does the same thing. Feeling overwhelmed I think maybe it is a video card driver possibly (I say this because before I disabled event log I had an error for my nvidia drivers like stop @ 32 or something like that) and I load windows into "Low Resolution Video" mode and here I am talking to you guys. Before posting I tried uninstalling my video card drivers and reinstalling the most updated one from Nvidia's site for windows 7 64-bit and that didn't help. So I have come to the conclusion that I need help from anyone at this point LOL. Everytime windows decides to boot up fine I can't ever seem to re-create it. It's like its a hit or miss thing. Any help what so ever will be greatly appreciated because I am stuck. I can always re-install my OS but I feel like its fine because it lets me boot to windows sometimes and EVERYTHING works. I get no errors or blue screens it just doesn't stay working for long.
