Need some help urgently

[natalo77]

Hi
My computer has been running oddly for the past month, usually black screening and speeding the fans up. after this happened I needed to hard restart the computer.

I have a hunch that overheating was the issue due to the case being very hot during the crash.

However that isn't my issue, about 10 minutes ago I disconnected the computer and ran some compressed air through it to get rid of a lot of dust residing within the case.
Now the computer boots but there is no input to the monitor.
The fans run, everything seems like it's running fine but there's no input to the monitor so I have to hard stop my computer.

Need help urgently

Thank you in advance for any help

maybe gpu issues or psu or.....

I know what they are... all I want to know is how/whether or not the compressed air has damaged my hardware

maybe try to reseating the gpu , by removing completely and spray with compressed air to remove the dust in pci-e
reinstall the gpu and give a try

let me know
