PC starts but doesn’t boot and no display, plus LED emits red

[Mostafa_Sabry55]

Hello everyone, I’m back with yet another question...

So this happened from 1 month, I had my PC start but not actually boot or beep (successful POST), But I did a hard reset (turn off the pc, also removed cable from my PSU to make sure it doesn’t start by itself (yes after HR it does start by itself and fails to boot)) and it worked! This kept happening from time to time, But this occurred today with different symptoms.

So I did what I used to do. Hard resets, re-plugging the power cords and stuff, pressing the numberpad lock thing to test if its my monitor or not, etc.

But, after some tries, The LED turned red and PC kept beeping continuously, I looked at some post related to this issue, but they stated that white lights would emit from the diode or that there was supposed to be long and short beeps, and that the codes can be identified through the first 5 iterations, even builds before 2010 (Yes, it’s so old...) indicate that, and the fact that mine was continuous and not shown as something that could happen drove me crazy.

But if I’m not wrong, The problem should be something in the PSU, RAM or something dust related. (I’m hoping that it is not RAM, GPU/CPU or the MotherBoard, as it’s really old and probably has no replacements)

Do not tell me to buy a new one, my dad won’t let me buy one and wont fix my main laptop (If you’ve seen my last post) , as this is my one and only backup PC, I don’t know what to do...

And by the way, I would love it if you tell me why PCs die even if you take good care of them. If this is relatable, I live in a dusty hot humid area (Egypt).

Please help, I’m waiting for your answers, anything is really appreciated.

Anyways, Thanks for your time!

Peace.

Ok so a quick new update, I blew the dust in my pc (Crap, there was a wall of dust into one of the inner walls, fans where filled with dust, everything) with care, done everything correctly then attached all cables to my pc, it didn't work and beeped 6-7 times (it actually wasn't continuous then, perhaps it was me being imaptient), then I did a hard reset, powered it up and it worked (Plus it did a successful POST beep) !

Iam sure something isn't really right over here. Like, If a component is broken but still works occasionally, would that mean something? Like is it standing on its last legs, Luck or loose? I really do not understand whats going on...

Anyways, Peace!
