Last week my computer started taking a lonnnng time to start booting power light on, harddisk light blinking, black screen. Sometimes it would take 30 minutes to an hour for it to finally show something on the screen, ultimately the asus logo would come up and boot. Now it wont boot at all. Same symptoms power light on, charging light functions normal (orange when charging, green when full), blinking harddisk light (once every 3 seconds or so), CAPSlock light is always on for some reason. I tried reseating the RAM. Nothing. Connecting to an external monitor, nothing, so that rules out a bad display or display connection.

I am thinking it could be GPU. Maybe I need to reflow the chips? I just dont have the experience, so I dont want to try that. Maybe the motherboard is going bad?

It sucks that this is 2.5 years old and the warranty was only 2 years. Now its broken

Do you have a motherboard battery thing? It should be shiney, silver looking and usually disk shaped. It will be about 1 inch in diamater. Take that out, boot, then put it in, then boot (MAKE SURE YOU DO NOT SHOCK THAT, IT IS LIKE THE LIFE OF THE BIOS). I did that and it fixed my issue that was similar to yours. Also, look online how to reset a bios via giving an electrical signal to a certain pin on your motherboard. Your motherboard may also have a slo-mode switch. You could try flipping that, without doing the other steps, or do them all and see what happens.

Since he is talking about a laptop... No.

I can't see it being a GPU problem, unless you've shorted it out, the most likely cause of this would be a failing HDD...
