Windows 7 Black screen help

I am running Windows 7 RC 64bit on my desktop. When I leave the desktop running for long periods of inactivity without putting it into sleep mode I run into problems. The monitors looses display and nothing (moving mouse, banging keys) will turn it back on. The only way to turn it on is to manually press the button and restart it. Once I restart I get a black screen followed by one of the following two errors.

NTLDR is not working
or
Disk read error has occured

Both require me to go into my bios and edit my primary boot device back to my main hard drive. With the NTLDR error I often find that my primary boot device has been changed to my external hard drive. Disk read error obvious shows up with my hard drives having been disabled from boot all together.

Does anyone know how to fix this black screen error or what might be causing my comp to behave like this (fucking with boot devices)?

I have scanned my comp with AVG, avast, symantec, and malware bytes so I highly doubt it's a virus.

bump cuz I really need this solved

It sounds like your computer is going into some form of standby:



I realize you have Windows 7 and I'm running Windows XP. But it could be this. The boot device order could be getting messed up by hard restarting (just pressing the power button).

Let me know if it works, I am very good at figuring out more solutions if it doesn't.

I'll PM u if any further problems arise

Could be that your bios power saving options are not set in a manner that windows likes. Try finding them and switching between S3 and S1.

if your running beta, switch to rc1 that fixed all my issues with stand by.
