Another Black Screen problem.

Sounds like your CPU is overheating under stress. That would explain the black screen problems. Given the malware, which I highly doubt was due to the stress test programs if you got them from the correct source as I have done numerous times, I highly suggest you start a thread in System Security - Windows 7 Forums.


To help with the overheating problem, make sure the system has good airflow and all dust is cleaned from the system:

Dust Removal:

To remove dust, follow the subsequent general procedure. If you have a desktop bought from Dell, HP, Sony, Lenovo, etc. make sure removing the desktop casing will not void your warranty first. Call the company if you are still under warranty and ask if it is okay to remove the casing and blow dust out. The procedure described is fine for laptops; just make sure no stickers are on panels saying if you remove the panel it will void the warranty.

1. Shut down and turn off your computer.
2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
4. Remove the casing for a desktop, or remove any screwed on panels and disc drives for laptops.
5. Blow out the dust inside by using a can of compressed air or a low pressure compressor. You will want to put the computer on a desk or table so you can maintain the can in an upright position if using a can of air. Blow into all crevices on the motherboard, heat sinks, cards, modules, etc. for a desktop. Blow into vents, opened panels, disc drive areas, USB ports, and the keyboard if it is a laptop. You may also want to blow inside the disc drive by replacing the drive to the laptop, starting the computer, opening the drive, and then turning off the computer and removing all power as described above including the 30 second power button step. For a desktop, you may also want to blow inside the disc drive by starting the computer, opening the drive, and then turning off the computer and removing all power as described above including the 30 second power button step.
6. Replace casing for the desktop. Replace panels and disc drive (if you have not already done so) for the laptop.
7. Plug power supplies in. AC adapter for the desktop. Battery and then AC Adapter for the laptop.
8. Start the computer and see if performance is better.

Easier Laptop steps:

1. Get a can of compressed air...
2. Shut down and turn off your system...
3. Unplug the system from any docking stations...
4. Remove the AC Adapter and then remove the battery...
5. Hold down the power button for 30 seconds to ensure all power is drained from the components. This closes the circuit and allows any remaining power to dissipate; it also clears the temporary memory of corruption and resets hardware/software connections. No permanent changes are made to the system doing this step...
6. Use the can of compressed air to blow into every vent, crevice, keyboard key, USB port, VGA/monitor port, etc...
7. Replace the battery and then plug in the AC Adapter...
8. Replace the docking station...
9. See how the system runs after doing all these steps...

   Warning

WARNING: Never use a vacuum cleaner or hair drier to clean dust out of your system!!

I believe the malware came from the sponsor links (accidentally clicked) found on the same page as the correct download links.

So is the CPU overheating during boot or is the CPU damaged from being overheated in the past?

I can't believe the quality of Gateway laptops. This laptop is only 3 years old and already has a major problem. I have taken great care of this computer by always laying the computer on a hard flat surface. Also, I always remove the charger from the computer and wall when not in use.

At least I know this problem was not caused by Glary, but by the manufacture.
