Windows 7: Black Screen

Black Screen

Every time I turn my computer on after it's been off all night it will just sit at a blank screen while my monitor says "No Signal". After about 3 minutes or so, it will finally go to the BIOS screen and then on to booting windows 7. But, when I'm in windows it takes about 3 minutes for my mouse and all other USB devices to start working. I just updated my BIOS and all drivers too see if this would fix it but it did not. Any help?

I am also getting a lot of blue screens randomly now even after cleaning my registry and finding no errors after running memtest over night.

Please test two things first:
1. run in safe mode (for a longer period of time, a pia, I know... but it helps us to know if you also get BSOD's then)
2. Run SFC /SCANNOW Command - System File Checker - Windows 7 Forums

later today I'll be able to look at the upload... maybe someone else will sonner...

Hello DXGuitar,

Your system has a couple of potential problems:

Please finish the windows updates that apparently have been aborted. If needed, one by one, manually.

You have a warning that could be solved by doing a clean install of your Nvidia stuff (see later on):

Security Processor Loader Driver ROOT\LEGACY_SPLDR\0000 This device is not present, is not working properly, or does not have all its drivers installed.
The following driver needs to be updated, normally this happens through Windows Update:

I might hazard a guess that you are OC-ing? If so, for the sake of finding the real problem, please go back to default settings.

Some of your dumps could be pointing to videodrivers. There have been a lot of problems with Nvidia drivers/updates etc in the last couple of months. It wouldn't hurt to check that by:
1. De-install ALL Nvidia stuff the normal way
2. Go in Safeboot and use Phyxion.net - Driver Sweeper to really clean the system of nvidia
3. Reboot (as you probably know, you'll get a low res screen) and download and install the latest Nvidia drivers for your card from here: NVIDIA DRIVERS 275.33 WHQL

I'm not OC-ing but I have in the past. I have also done clean installs of my Nvidia drivers but I haven't used Driver Sweeper to do it. So I guess I'll try that.

I think I have figured out the problem. I ram memtest again but in a different slot on my mobo and found 3 errors on one stick, so i decided to boot it with the stick that got no errors and I have had no problems since. It will not even boot when I put both sticks in so I am going to see if I can have corsair send me another stick.
