Laptop keeps shutting down

[ovidiutaralesca]

Hello! My father disassembled his laptop today to clear the dust. It went well, he cleaned it with alcohol. He did not touch the cooler, he only took the fan off and blew the dust built within.
When he powers his laptop up, after the Windows 7 logo, the laptop shuts down. This makes me think of CPU overheating, but it doesn't really make sense since he did not remove the cooler.


He managed to boot in Safe Mode, but after he attempted to use HP Recovery Manager to restore the laptop to factory settings (the restoration failed somehow), he gets an error message in Safe Mode saying that the computer has gone through an incomplete restoration.
Could it be the Hard Drive?

Unfortunately, there is no computer service anywhere near him, that's why he did this by himself. He had cleaned the same laptop a few times before and everything was fine. I'd be glad if someone could help me.

The laptop is a HP Pavilion G7.

Sound worked by default. He installed network drivers and they worked. I forgot to mention that before he started cleaning the dust, the laptop was in stand-by, without battery. He force-stopped it. May this be the cause of the fault?

download the correct sound drivers from that link. don't think so on the fault.

Typically a force stop when in stand by, suspended, or hibernated hasn't caused any problems in my experience unless prior to going into that state it had installed updates. Windows 7 will typically roll back the updates if necessary upon reboot. Occasionally take one or more reboots, then prompt you for any rolled back update(s) again.

Since this model according to HP has an Intel Core i3 processor it will have the Intel Chipset, which will include the Intel VPU on the motherboard. However, on many laptops the interface will not be exposed to the outside for connectivity. In the base model, it was available with the Intel HD Graphics 3000, however it appears that more advanced models might have been available with either the AMD or nVidia VPUs. Unlike a desktop, the advanced options would not expose the onboard Intel Graphics Adapter. But that explains the confusion on which graphics adapter you should use or install on a rebuild.

As far as general rebuilds, I usually start with the chipset drivers which often helps Windows recognize onboard hardware and either automatically detect and download the drivers or allows Windows to tell you what drivers it needs during the detection process.
