Compaq Presario CQ57: Computer will turn on, screen won't.

Fri, 30 May 2025 01:57:15 -0700

My computer will turn on, and it'll give me a couple seconds to go to the start up menu, but beyond that the computer screen stays blank. When I try the options on the start up menu it will just turn the computer screen blank. I've tried the removing battery and holding the power button. But that hasn't changed anything. I don't have the material to connect to another screen, let alone know how to do so.

My friend thinks it has something to do with a virus. I gave her my computer to try to fix and she said she found 9 trojans and several other minor viruses. It's a used computer and I can't afford a new one.

Any help is appreciated.
