PC won't Boot

[Irish_Ninja]

Hello to all.

This is my First post and I hope that someone can help me out.

My Gaming Rig comprises of the following: Asus P5Q Pro, Q6600, Corsair 750w psu, Ati Saphire Radeon HD4890, 8GB(4x2gb) of Corsair Dominator 1066 Ram, 150GB Velociraptor, NZXT Lexa Blackline blue, Coolermaster V8 CPU Cooler.

The Problem is that it was knocked over onto its side onto tiles and the only initial obvious damage was that the wireless usb reciever for the mouse was bent and broken. unfortunately I was not there when this happened and I only found out about it when I came home and the pc wouldn't boot. I noticed the bent usb reciever and removed it, made sure there was no debris inside the usb socket and tried to get it to post or boot but it wouldn't show anything on-screen at all. just black.

I then disconected the effected usb's header from the motherboard and that had no effect. I have obviously checked all connections aswell. Disconnected hard drives and seen if that had any effect on proceedings. nope.

Took cmos battery out and reinstalled in an effort to reset the bios. nothing. At this point I should prob mention that it starts up lights, fans, HDD's, GPU but the screen stays blank. These have been the symptoms through out.

Stripped everything out thinking that perhaps a rogoue screw had fallen in under the MB and was grounding something from when it fell. Nope.

Rebuilt everything including reseating the cpu, applied new arctic silver compound. Re-installed MB, Ram, GPU, all cables, HDD's, CPU Cooler...Everything except PSU which remained in the case. All resulted in the same symptoms as before. tried different combinations of ram. nada.

My thoughts now are either the MB or the GPU or possibly the PSU are Stuffed?

What do y'all think?

I would Appreciate any help.

Thanks, MJ

If the PSU is at the top Id think that or the motherboard tbh. The only way you have to find out is to swap parts sadly fella. You have to go through the whole fault finding process to get an accurate answer and I think thats probably why everyone has avoided what would just be guesses otherwise.

Sounds like motherboard to me. Attach a speaker to the mobo if there isn't one built in and remove the ram and try to boot. If you don't receive any beep codes the mobo is most likely shot. Do you have a large heavy heatsink on the CPU? That could have damaged the board on impact of the fall.

Try any parts you can in another rig to verify that they are working. GPU especially.

Ok, thanks tom. I'll try get hold of another psu to test things with that. psu was on top alright.

hmmblah, thanks for the reply. I tried listening hooking up earphones to the rear built in audio jack on the mobo but heard nothing. I will check again using the audio on the case that connects via a header on the mobo and see if it's the same story there.

The Cpu does have a big and heavy cooler on it alright the Coolermaster V8 so possible damage done there.

I have also noted that the GPU seems to go through it diagnostics and pass on boot as it flashes 3 lights but they go off again, which I have read is good.

Cheers.

There should be an internal audio connector labeled speaker on your mobo. It will be with the LED and power switch case connectors. It's 4 pin. That's the only place you will hear beep codes.

I went to a friends house today to use his rig to do some troubleshooting. Long story short the gpu was causing the problem. Any idea what would likely have gone wrong with it? Should I consider it a brick now? I would hope there is a chance of repair

cheers, MJ

Tried the oven treatment? Pop it in there, prop it up on something so it doesnt touch the sides, put it on 85-100 degrees( C ) and cook for an hour. Pop it back in the case. The point of this exercise is to re-solder any tracks or components that are broken off or moved.

TBH you have gotten off pretty light. The GPU shouldn't really cost that much to replace and it gives you a perfect excuse to get a DX11 card
