Computer Problems Again

[mihir]

I decided to clean my computer and shift the computer to my room.I completely disassembled my computer and also my case.Since I also had to install my case's new front assembly.
I also opened up my GPU and cleaned it and applied new thermal paste.
I then reassembled everything and to my horror discovered two things.That my computer is not posting and also my GPU fan is not working.
I opened up my GPU again checked the fan connection and it was intact.I also checked if I hadn't mess something up and I am pretty sure I haven't.
I tried another GPU about whose working I am doubtful about,its fan works perfectly.
Now my GPU fan is not working and neither is my computer posting.
I have tried everything.
Resetting my BIOS,removing all the RAM sticks and also posting just with the motherboard CPU and no GPU and Memory.But the damn speaker wouldn't make a beep.
It seams like a bad Motherboard but what could have happened in disassembling and re-assembling.I always take good care of my hardware when out of the box and also my motherboard was recently RMAed.
I have written to XFX about the GPU issue but they told me to take it back to the reseller.And the reseller wouldnt take it back claiming that he is supposed to take care of only 1 year of warranty and the rest should be taken care by XFX themselves.My card is registered on the XFX site since the 1st day of purchase onwards.


Also my computer is not posting.
I recently purchased a Seasonic PSU which is not even 2 months old could something be wrong with it.
I use my computer with a belking surge protector.
Why does this always happen.When ever I disassemble and re-assemble my computer it stops working and at the end something turns up bad.
I really don't know if they will RMA my motherboard again since already they have provided with a replacement.
And also as for the GPU any help would appreciated.

Why do you feel obliged to take your PC apart? There is plenty of monitoring for temperatures, voltages and speeds. If it ain't broke, don't fix it. The occasional dusting is all that's needed. The only moving parts are the fans.

Everything you have described would occur if the PC was turned off. Are the main fans powering up? You won't get a beep without power. What is running, making sounds, flashing etc?

 

[mihir]

I like to take my pc apart for dusting my case since I am using a really strong electric blower and you won't believe the dust at my place.All the fans turn on the power led flashes the southbridge light turns on and the the other GPUs fan turns on but my GPUs fan does not spin.
No beeps no sound.

 

[StrangleHold]

You did plug the 4/8 pin CPU power connector back in?

It sounds like you've done the usual things to get a boot going. It would help if you had a graphic card that was known to be working OK. Presumably that was OK before the shutdown. You should make sure the card and connections are well-seated. I could not get a manual for the card since XFX support is password-protected (duhh).

It seems unlikely to be the PSU - it's new and if it had problems you would have seen that prior to shutting it down. You can test the voltages if you have a multimeter. As you know it's near-impossible to test the MB other than by ruling everything else out. If you have already sent one back that's not a good sign. Can you get into the BIOS? Any iffy settings? I don't have any other ideas.

The keeping clean issue should be easy to resolve. If the PC is near or on a carpet, put something under the pc that extends 3-4" from the PC especially near inlets to reduce fluff (I use stiff card, hardboard or high density foam). If it's a very dusty environment, dust out frequently rather than the occasional "dig out". In extreme cases, add inlet filtering and size the fans so the case is slightly pressurized (input capacity greater than output capacity).

Try and locate the PC in still air away from walkways so any dust from outside drops out somewhere else. One of my PCs is near a heating air outlet. I made a curved card baffle to direct the air away so that the PC is neither heated, nor in turbulent air that is going to stir up the carpet.

There's no need to renew the thermal paste every 5 minutes. You have temperature monitoring. All edge connectors are relatively delicate. Once a card is in, leave it there. One of the advantages of the Dustbuster compressed gas cleaners is that you can do short, sharp aimed bursts that provide the maximum dust removal effect. The downside is cost.

But What could have happened so severe in shifting to screw up my motheboard again.

I changed the Thermal Paste after 1 year.My PC was in a not so ideal location and was shifting it to an ideal one.And I dust out my PC every week.I clean my keyboard and mouse and the outer vents of the PC everyday.

...But What could have happened so severe in shifting to screw up my motheboard again....

It could also be the CPU this time. It's very strange and must be frustrating. Hang on and see if others have ideas.

That's pretty bad dust....but not during the monsoon! You said you just RMA'd the MB so the paste must have been fairly fresh.

It's the inlet air that you need to filter. By sizing the fans properly for the unusual circumstances, air will only enter via the inlet filter, not through any other gaps in the case. It's more difficult to do with a PC than some other electronics due to the PSU fan. Industrially, you would only have an inlet fan with filter. In exceptional circumstances and corrosive atmospheres, you would purge the enclosure with dry instrument air. The idea is to remove all particulate and have the enclosure above atmospheric so leakage air goes out, not in.

BTW you can edit quotes, just like html. The initial quote code has the other person's name. All you need is a QUOTE in square brackets at the start of the section you want to quote and a /QUOTE in square brackets at the end (including for the first quote). You can repeat numerous times, deleting irrelevant parts and adding your own comments in between as I just did with your comments. Preview before posting. Saves a lot of forum space.

The GPU thermal Paste not the CPU.
Yeah the dust seen is pretty bad here.I have to clean the dust off my keyboard 10 times a day.
I still don't get why my GPU fan is not working.I plugged in the GPU fan power properly and I checked and double checked but still the damn fan just wouldnt spin.
I hate how the computers are so unpredictable.
Once I faced an issue where I just shifted the GPU from one PCI slot to another and the computer worked and then I put it back to the original slot and then also it worked.

Posted from my Blackberry,that is why

....Posted from my Blackberry,that is why

See, there are advantages to buying pre-built (the Blackberry works)!

If you have that much dust perhaps that is affecting the MB by bridging tracks or connections. It will certainly shorten the life of unsealed fan bearings. Usually in areas like yours people have found methods of overcoming these things (mother's old panties, a few car filters?). You can buy proper inlet filters, which you may already have.

Do you have a GPU fan speed controller that has gone belly-up?

 

[mihir]

You did plug the 4/8 pin CPU power connector back in?

Oh sorry stranglehold just read your reply.Didn't notice at first



Yes I have plugged in the 8 pin CPU power connector. :good:


EDIT

I keep my motherboard extremely clean.
I can post a picture if you want it looks just like new.I clean it every week or so.

And nobody can convince me to buy a prebuilt PC except Apple(if they lower their prices).

 

[mihir]

I will be RMAing my GPU.But I just discovered that XFX stopped making my card, and the only NVIDIA cards they make are below my GTX 275 in performance.
So do you think they will somehow arrange a GTX 275(I hope not) for me or do you think they will give me an AMD Card.Of equivalent or greater performance.
And if it would be an AMD card which one do you think they will give me. HD6870 or something else,or an HD5830.

 

[StrangleHold]

Dont really know. They suppost to give your a equivalent or better card. Could talk to them and see if they will give you a choice of what cards they might offer.

Any advice on the Computer Post thing.
Do you think the motherboard can be gone again,since it is not even giving a long beep without the memory plugged in.

I hope they RMA my GPU.

And is the card equivalent on basis of performance or price.
You get what I mean right??
I mean like the GTX 275 was only next to GTX 295,GTX285,GTX 280,HD4870x2 at that time.So would they give me a card of equivalent ranking like the HD6950,equivalent or more performance like the HD5830

 

[StrangleHold]

In perfomance.

Its really odd man. You said you tried another GPU in it and the fan worked, but still didnt post?

Maybe try taking the board out of the case and putting it on a box and just put the CPU, one stick of memory and the GPU. Hook the power supply up to it and see if it will fire up.

Will do it tomorrow.
I seriously hope it works,I don't want to RMA my motheboard again.

 

[StrangleHold]

Have you changed the boards battery. Most will post with a dead battery and just reset the bios to default every time you shut down. But I have seen a few that just goes nuts with a dead battery.

Won't hurt trying.
Will get a new battery and replace.
Tomorrow I will be considerably free will try everything to make it post and then will report back.
God what would I do without my motherboard speaker.

I still don't get why it got screwed up in just shifting from one room to another.

Have you had such un predictable experience with a computer.
I will also try another PSU.

Just trying to think of things you can try that dont cost anything or very little.

Oh yeah. Sometimes it was just stupid things I over looked, like not plugging in the CPU 4/8 pin power connector or the video cards PCIe power connector or the Bios jumper set to clear.

No I mean things like,
swtiching the GPU from 1 PCI slot(not posting) to other PCI slot and booting and then switching it back to the old slot and the computer still booting.
