Okay so a few of you may have seen my recent post about my CPU temp being high.

So I did that, but while purchasing the compressed air I was told to REAPPLY the thermal paste, because most likely it has worn out. I took off the heat sink, bashed a few things here and there (I got pretty clumsy), put on some new thermal compound, cleaned the heat sink, put everything back together and now there's no display on the computer.

One thing that seems important was the guy in the shop told me I didn't need to earth when I asked him about it, because motherboards these days come coated in 'anti-static' coating, or something.

The GRAPHICS card fans are still spinning so it must still be functional, and it still boots up, but there's no beep when it boots up. Also when it's on I can't use the power button at the front, all I can do is power it off at the back.

Thank you for any help, I'd be happy to provide any more necessary information.


By the way, would it be better to try and fix the issue myself, or just take it to a shop to ENSURE that I don't cause any more damage?First thing I would do is check all power connections to the motherboard/GPU.etc and then reseat your RAM.  What things did you "bash"?

Did it beep before this when it started up?  Not all machines have speakers.It was pretty bad, I hit the ram a LITTLE, the heat sink landed on them motherboard when it slid down, and I dropped a screw into the GPU and had to fish it out. God I feel like such a clumsy idiot lmao.

So what do you recommend, just taking the parts out and putting them back in? The GPU has power to it for CERTAIN, the fans are still going.

The computer used to make the beep noise, but it doesn't anymore, which leads me to think there's hardware failure of some sort.

At this point I'm just hoping its simply the mobo needs replacing, if so it'll be pretty cheap compared to other things, also if I plug a monitor into the onboard graphics, there's no display either. I hit the mobo the most and it looks like that's what it may be to me, just wanted some other opinions.
