I have a home built computer running Windows 7 that takes about 40 minutes to boot. It used to take about 20 seconds. Once the computer boots the Windows sign on screen displays and then the monitor goes black. There is no video out to the screen.
I am using the onboard video on an ASRock Z77 Extreme 4 motherboard. The Windows Device Manager says that the video processor is "Intel HD Graphics 4000."
I booted into Safe Mode and was able to get video out to the monitor.
Before posting I tried some of the steps in the post "Slow Computer/browser? Check Here First; It May Not Be Malware" post. I tried the following (the numbers are the topics in the "Check Here First" post):
2 - Clean up your hard drive - Minimal files deleted./space freed up.
4 - Check for problem entries in Device Manager - No problems found.
5 - Check for damaged, missing or altered critical system files by using the System File Checker - No problems found.
7- Check for unnecessary applications loading when windows boots with the System Configuration Utility. I used the startup tool in CCleaner and noted one potential problem. There is a startup item called Conime. The bleepingcomputer database of startup items says that this may be a valid Windows process or may be malware installed by the W32.Slurk.A worm or the Troj/Dldr-G trojan.
I have AVG Free antivirus installed but it will not run in Safe Mode mode. I also have Malwarebytes Free installed. I started a virus scan with Malwarebytes and it has been running for 45 hours. So far there are no infections reported.
This computer is six or seven years old. The operating system is hosted on a 160GB solid state drive. The data files are stored on a regular hard drive. I think that there may be a problem with the SSD that hosts the operating system. It is an Intel 320 Series SSD Model # SSDSA2CW160G3.
When I built the computer and installed all of the software I seem to remember that the complete installation only took up approximately 10 to 12 GB of space. Since that time the only additional program to be installed is itunes. Right now the drive shows that there are 90GB of space used. Virtually all of the data files are stored on the traditional hard drive.
Although I built this computer I just followed instructions I found on the internet and I barely understand what I am doing. Any help you can provide in figuring out the problem will be greatly appreciated.
I think that my next step will be to update the video driver.
