Hi all,

I recently acquired an Asus EEE Top PC (ET2203T)... an all-in-one PC which was going to be used for admin and basic music software bits - nothing too intensive.

I got it home from my friend dropping it off and it worked fine for the first day before eventually overheating and cutting out. I managed to open it up and a thick layer of dust had accumulated on the heatsink where the fan blows on it, so I cleaned it up and put it back together. Turned it on and the screen was blank for about 8-10 mins, then the EEETop logo came up, and another 10 mins or so later it tried to boot but 'Keyboard/Interface Error - Press F2 to continue' came up. The wireless keyboard was useless, as was a USB one and there is no PS/2 slot on there so it was a bit of a problem.

After a while of trying to get into it by just rebooting it, I opened it up again, and relaid the thermal paste on the CPU and the graphics card (ATI Radeon 4570 HD), put it back together and lo and behold, it started running again! Speedfan was giving ok (not great but ok) temps of around 35-40 for the HD and 60-65 for the CPU. The cooling system in there is pretty crap but keeping that in mind it's ok.

This worked using Cubase with limited plugins, browsing the internet, using torrents etc - all good - until eventually I played a video on YouTube and it died again - the screen froze and sound stuttered and looped the millisecond it crashed until I turned it off again.

Turned it back on - back to square one with the issue. Once again, redid the thermal paste and it worked again for another day or so, before I tested YouTube again and it died again (please note that I have used XBMC and Windows Media Player for videos with no issues - the crash leads me to believe it's the video card).

This time however, I've cleaned the thermal paste and it is still taking forever to load the BIOS and refuses to recognise the interface. I've redone the paste a few times now as well as testing other things, including:

- Removing the RAM to see if it's a dodgy stick or slot - the RAM is ok
- Removing the graphics card and switching on - still the same issue

I don't believe it is a hard drive issue either or just simple overheating... please help!

Just to re-iterate:

- Computer crashed when playing YouTube video (flash issue?)
- Now takes about 10 minutes to attempt to load the EEETop flash screen
- Then takes another 10 mins or so to then tell me 'Keyboard/Interface Error'
- Cleaning and replacing thermal paste has worked a few times but has stopped making a difference now

Thanks for taking the time to read this, any help would be greatly appreciated!

I agree that it's not the hard drive as the bios/post screen takes a long time as well as the OS. I also agree it isn't "simple overheating" but more of a complicated, damage due to constant/often overheating (your friend may have been experiencing the same thing which is why you were able to acquire it from him/her)

This sounds less like a GPU overheating issue and more like a PSU, motherboard overheating issue. Something (a capacitor or resistor, both are sensitive to heat) may have been damaged by the previous overheating(s) which lead to shut down(s) and is now only partially functional. When enough current and heat are applied to this damaged piece it causes another shut down.

So in my opinion it sounds like the power supply (I'm not sure if they are referred to as a PSU in these types of units) or the motherboard.

From opening it up it's essentially a custom laptop motherboard... the PSU is an external unit like a laptop power cable. My concern is that I don't particularly want to start throwing money at a system with no real replaceable or upgradeable parts. If it's not the external PSU after I replace it, what would the logical next step be wirh regard to testing the motherboard for issues?

Thanks for the reply!

To test the motherboard I would have no idea. From what I've been told, testing the motherboard requires specialized equipment in a high-end shop (the local shop on the corner or the decent shop in town won't be able to do this sort of test)

I would NOT replace that type of power supply. The exterior component will not have suffered from overheating damage. It is the internal components ( I assume that are part of the motherboard) that need to be replaced.

Since this type of computer is essentially a laptop, you may want to ask in the laptop forums about this issue and how/ if you can resolve it. If this were a regular PC I would tell you to replace the PSU and if that didn't correct the problem (which because of the type of unit this is, it won't) I would recommend replacing the motherboard. On a unit like this I'd say that option is not worth it.
