Just out of curiosity: is it plausible that a CPU with too high TDP fries an underspecced motherboard?

My old desktop became flaky last year, clearly overheating something (judged by smell) until crashing.
Spoiler (click to show/hide)

I took the thing apart and looked at it closely over the last few days, and some circuitry very close to the socket looks sort of... caramelised. Some guessing and web searching shows it's all full of hefty el-caps, power mosfets and throttles, so i suspect it's stuff that provides power to the CPU.
The CPU is an AMD 64 X2 with an ADXnnn identifier - i.e. a 125W TDP processor and the handbook of the motherboard says it can only handle up to 95W TDP; so the OEM slotted in an over-hungry CPU (good job!). The computer worked reliably for ~6 years before getting toasty, which feels plausible for a slightly overburdened circuitry holding up but with significantly reduced life expectancy.

Nothing else in there looks really suspect (no bulging capacitors, no other charred/tanned spots on the board), so is this a likely event? I've just been wondering what exactly messed up the thing. Considering it was a really cheap pre-assembled desktop in 2009 or /10, repairing's out of the question and even the spare part value is strictly self-use or donation.

Many motherboards put a bunch of lytic capacitors all around the cpu socket.  Those contain liquid electrolyte, which will vaporize if it gets hot enough.  Look for barrel shaped metal cans near the CPU, and look to see if the tops are bulged, or if orange goo has leaked out.

I took a second look through the elkos and they all look normal, no bulging, no leakages. The only suspicious thing on visual inspection are the solder points of the power mosfets, which have a brownish sheen. That's why i guessed it might have been the overspecced processor drawing more juice than the transistors could safely deliver, wearing them out over the years. The effect is visible on three of the four mosfets around the CPU socket and not on transistors installed anywhere else on the mobo.

It was a very gradual, almost "soft" failure, as described - the computer could be rebooted and worked normally after rebooting at first. Only after several weeks did it fail to reboot properly. The faint but distinct burnt smell was a clear sign it was a heating issue, and getting the dust out of the fan and radiators made no difference, suggesting it wasn't the processor which was getting too hot.

As mentioned, it's mostly curiosity/diagnostic interest. I'm not likely to buy another machine from that manufacturer anyway, but if their poor system composition actually reduced the lifetime, it'd be pretty damning.

Mmmmh, so I have two gmail accounts linked to thunderbird (latest version) on my windows computer. I just realized now, but apparently, they stopped syncing on 31/12 and I can't get them to update, no new mail shows up. I tried deleting one of the account and re-creating it, but it won't let me (says the username or password is bad, but they are the good ones, and work in the webmail).

Any hint of what it could be?

Configured as imap or pop3?

Also, did google decide to revert an account preference that enables remote mail?

Most likely, you've been spontaneously reconfigured not to allow what Google deems "insecure applications", which happens to me regularly because Google is terrified that someone might not be using Google-approved software.

Happens on my ancient Hotmail account frequently as well. They are terrified that you are getting service out of them without giving them advert impressions. (Oh, the humanity!)

I finally found a solution to my computer's virus problem.

https://malwaretips.com/threads/fake-windows-process-manager-virus.76916/

In this forum thread there's a link to a rootkit remover. I used it and it seems to have worked - the "Client Service" and "Windows Process Manager" items are gone, and I can delete the folders I previously couldn't.

Bay12, I am in need of assistance. I have a laptop. It has to inside-of-it storage thingies where I can put files, C: and D:. C: is also a super speedy ultra thingie that speeds super fast. It is also a lot smaller than D:, the ordinary storage thingie. Well, the computer pretty much defaults to store everything in C:. Which fills up really fast.

Lately I've been having to put unordinarily large files in C: because I've been modding NwN and it's toolset requires you to put new assets in the C:/Users/MyDocuments/NwN folder. It fills up super really fast when you do that. I really annoys me. I don't really want to wast the precious space of the fast drive when I could store all these NwN assets in the spacious hard drive.

So. Do you think there is any way I could change my laptop's structure of whatever to make D: the default/primary drive for random everythings, so that all the User stuff and computer system stuff would go in there instead of C:, and so I could keep the super ultra gotta go fast drive for things I actually want to go even faster stronger better than?

Have you tried opening my computer and right clicking on the my documents folder? On my laptop one of the options the folder has in its properties is location, which can be changed.

That would be great and make me feel like a complete idiot. I assumed the computer needed it in that place because of the whole "user" stuff setup, and that it would just create a new documents folder there if I tried.

Anyway, trying immediately.

Have you considered using junctions? ;P

https://en.wikipedia.org/wiki/NTFS_junction_point

Or even, abusing a .vhd with a mount point?

Basically, you can keep the path on the C: drive, but have the files physically stored on the D: drive, if you know what you are doing.
If you don't, thats OK too, as there is a handy shell extension to ease the pain you would otherwise have to endure at the command prompt.

Despite the name, it does both hardlinks and softlinks. (to link to another partition/drive, you have to use a softlink or a mountpoint.)

Thanks for the response, guys. Khan's suggestion above seem to have worked. And I feel like a complete idiot :P

Yeah, first thing I generally do after setting up a new computer is move all the my documents, pictures, etc, into the D drive, where they won't go missing if I have to wipe windows or something similar.

I picked up a trick with some old(er) windows 8(.1) tablets that have very limited internal flash storage.

First, you need a filter driver to make windows view the external SDcard as permanent storage-- Then you can use something like symmover to move files out of the program files location, and onto the formatted SDcard, and then abuse symbolic links so that programs think it is still on the C: drive.

Similar approach would work fine for big programs that *INSIST* they must be on the C: drive (unless they use hardlinks. Thanks MS! I love how all your shit does that now!), meaning it would work great for systems with an SSD and a traditional spinny disk. (you just dont need the filter driver, for obvious reasons.)
