Hello. I need your help. I'm stumped!!!
For the past few days now, I am having an issue. I am 'now' using Windows 7 Professional 64-Bit. I was using Windows 7 Pro 32-Bit. This issue is with both.
This is what is happening:
Approximately 50% of the time (random) when I statup my desktop computer, immediately after the Windows 7 "Windows Starting" and animated Windows flag are finished, but BEFORE the Windows 7 Logon screen, I am getting 2 screens that are switching back and forth between a blank black screen with the pointer on it (pointer and the animated loop curser used by Windows Vista/7) and a blank screen with a so-called 'static' look on it with no curser at all (The 'static' screen looks like the old days that when you changed the analog channel on a TV and there was no TV channel there, you would get that black and white dotted static look). The switching back and forth lasts about a half a second each (very quick) and finally ending up at the blank black screen with no curser/pointer. I look at the HD LED on my tower, and it shows activity, but my screen remains blank and black. The compter never reboots or restarts on its own, it just stays at the blank and black screen. I have to manually reboot the system. Most of the time on the second reboot, I am able to get into my system successfully.
The other 50% of the time (When I am able to get logon into my system successfully.), after passing the "Windows Starting" screen, the blank black screen may hang for up to 3 seconds with the animated loop curser before I get to the Windows Logon screen successfully. When this happens, I never see the static screen and there is no flashing back and forth between these two screen as above. From past experience, going from the "Windows Starting" screen and the Windows Logon screen is only a very BRIEF half second of the typical blank black screen, not up to 3 seconds.
So there appears to be some issues happening at this percise momment each time when Windows 7 is starting. The only things I have done 'new' is update my BIOS (from the ASUS motherboard factory version of 1004 to the LATEST online download of 2209) and installed 2 more DIMM memory modules, so I went from approx. 4GB to approx. 8GB. NOTE: The BIOS settings are all set to "Auto" in terms of the "Advanced Settings" so the system auto corrects for the added memory. I contacted ASUS tech support, and they told me it would adjust itself automatically, nothing for me to do.

***Any ideas what is going on??
This is what I have done so far...
1. Assuming it was first a possible memory issue with the new memory, used Windows Memory Diagnostic tool & Memtest and there were no issues (passed) found from either test.
2. Checked Windows 7's Device Manager for possible driver
issues. No issues listed in listing.
3. Ran System File Checker (sfc /scannow) to see if there were any Windows file issues and there were 'no integrity violations' at the end of the scan.
4. Ran Windows Startup Repair to think the boot.ini file was damaged or some other Startup issue, and it found no issues.
5. Ran CHKDSK with the repair option, it didn't repair anything.
6. I verified that I installed all Windows 7's Windows Updates. I did and nothing new to install.
7. I downloaded and installed the latest graphic/video drivers
...and this issue still happens 50% of the time.
I then reformatted my Windows 7 Pro (This was a 32-Bit version.), and then installed the Windows 7 Pro 64-Bit this time. I installed the latest video graphic drivers, the latest motherboard drivers, latest Windows Updates, and I performed both memory tests both passed), Device Manager (no issues), System File Checher (no issues), CHKDSK (no issues) -- this issue still appears.
Of course, with a clean install of Windows, there 'should be' no issues.
What is going on??? Any ideas? ...and solutions?
Is there a setting possbily in my BIOS that I need to modify or adjust that is not 'automatically' corrected by the BIOS??? Maybe???
