Question about EliteGroup KT400 (L7VTA2 V2.0) Motherboard

Motherboard or CPU dead?

Hi, my computer recently stopped working and there was a terrible smell in the room. When I turned it on nothing would work. I replaced the power unit with exactly the same wattage unit and the computer would appear to supply power to the CPU fan, hard drive etc but would not boot up. Keyboard lights would also light up and the front LED would flash. However, after turning the box on, I could then not turn it off or reset it with the box buttons, so would have to turn it off at the wall. I have also removed all components except the hard drive and one bed of RAM in an attempt to troubleshoot, but still no joy. Have I fried the CPU or motherboard????????

Thanks for the help. Unfortunately I do not have the old PSU, but the smell, whilst not strong, is still noticeable when the CPU fan starts running, hence why I thought it may be the CPU. I have removed the CPU but could not find anything obvious, but will have another look. I have also removed the HDD and all ram, hoping the motherboard would give a POST error beep on start - but nothing! I will remove the motherboard and have a look on the underside for scorch marks. Any other thoughts would be greatly appreciated. Whilst I am learning, comparitively speaking I am still new to this. Cheers

Ragat40, If sandrews suggestions don?t turn anything up you may want to try this as well: If you still have the old power supply see if you can still smell the smell you mentioned. If not your failure may have been a capacitor, short or other failure on your motherboard. Check each capacitor carefully around the tops sides, bottoms and around the base on the motherboard. If that fails to find anything widen your search to the other devices, removing the processor and the underside of the board. The damage may be catastrophic and obvious or it may just be a black or brown scorched area. Let us know what happens and please don?t forget to rate the postings.

The smelling the power supply line sounds a little odd without explanation. When power supplies blow the smell tends to linger for a few days. If you didn?t smell the odor then that further points to the the board as the source rather than the power supply??

The burning smell (if it was a fishy type smell) may have come from the mobo psu 21 pin connector where you plug in the psu. The connection may not work properly because of melted plastic deposits which may be why you are unable to turn it off at the switch. Just check the old psu connector for signs of rusting pins and mis-shaped connector. If you have a fairly recent mobo and processor ensure that the power supply doesnt need the power supply from the psu, unlike some processors where the power is taken from the ZIF mobo socket.

Sounds like the power supply. May have blown. Make sure you get a power supply compatible with your motherboard.

I replaced the memory and turned the computer on and no video. no beep either.

Assuming you tried putting the old ram back and had the same result?
No beeps are indicative of a failed Power supply (check the PSU fan is working and the CPU fan is turning), Then check the ram modules are firmly inserted. Check the small 4 pin Black and yellow power rail that powers the cPU is tight.

After that, unplug, remove the CMOS battery, leave for 30 seconds and re-insert, try booting now.

If that fails, you have either got a fault on the mobo, or a dead CPU.

Testing the board with a known good CPU will confirm the latter.

Check the motherboard for blown and bulging capacitors, see if you can smell any burning from the board, either will indicate damage to the motherboard

You may have dew on the internal cabling and hard drives. This is potentially serious and it would be a good idea to switch it off for a couple of days and have it in a well heated room to dry out. Or if you are confident, open the computer and use a hair drier to blow warm....not hot air onto the hard drives and the compartment in general. This could save you the price of another computer!

A7V8X NOTHING HAPPENING,

When a power supply goes out the way yours did, it's going to fry the MB 99% of the time. So you're going to need a new MB. It's possible that you CPU is ok, but that could also go too. I would replace the MB first, then the CPU if that doesn't work.

Acer travelmate 4000 laptop Big problem

I guess I can assume that you have it plugged into the ac power, so you know its not a power problem. We also know its not a problem with the power switch since the light turns on. So that leaves, motherboard, cpu, and ram possible problems. Ram would unlikely cause such a hault. Even with no ram, I believe the computer would make horrible beeping noises. So if its a problem with the motherboard or cpu, its pretty much trash, unless you want to waste the money on ebay or some place for another cpu to try to swap.
