Help!! Friend's Rig Broken Shuts Down w/o Warning

I have a rig from a friend of mine. It's a Sony Vaio from BB with a 2.8 Northwood, 512 MB Ram, an 865/75 Intel Chipset and what appears to be an Asus 32 MB GF4MX video card.

The machine started right up and was working just fine for about 1/2 hr. and I actually emailed her saying that it wasn't acting up. Then right after that it spontaneously shut down. I mean it just clicked off and all the fans stopped and it was dead. This is the same problem that she was having with it. Since I had the cover off, I immediately started feeling for heat and trying to smell something either burning up or just smelling wrong. (Pretty scientific, I know.) Anyhow, no luck.

Thing is that when I try to start it back up, it's a no-go. All the fans power up and the HDD light starts blinking, but it doesn't post. The fans stay spinning at max speed indefinitely too, which is weird.

I have tried reseating the ram so far and that doesn't help. I need to grab a screwdriver to check the video card, and I'll probably also take a look at the PSU, although I am pretty sure that Sony would have enough brains not to cut corners on the PSU.

Does anybody know of any suggestions other than these? I'm leaning toward motherboard going to hell at this point, but I'm open to any input and suggestions from you all.

Also, as a sidenote, this started about 2-3 weeks ago and when it did, my friend went to BB to tell them about it. They said heat and that the case needed to be cleaned out. I'm not sure who did the cleaning or how they did it, but the sunofagun's as clean as can be now-which worries me because I am imagining paper towels and windex (I doubt that was the case, but scary nonetheless). Anyway-can anybody give me some suggestions? It's been sitting here, not posting for 45 minutes now but when I first plugged it in it ran fine for about 35 minutes. Lil help please??
 
I would vote power supply. Do you know what the system temps are? You should download motherboard monitor if you don't have anything for the temp information.
 
I will be trying another PSU today. Does MBM work on proprietary mobo's like this one? Any other suggestions if the PSU isn't the fix?
 
Those are classic 'PSU is toast" symptoms. If there is a harwdare monitoring sensor on the board, Everest Home edition should be able to report the temps under the sensor tab.
 
Definitely sounds like a PSU issue. I would keep the case off if you think it's a heating issue. This should give you time to install MBM and monitor temps. Also, the PSU may have caused damage to the video card or RAM, so you may end up having to test with different components once you swap out the PSU until you get it to post.

I would think it would. Looks like a prolly standard Intel chipset. D/L, install and see, won't take long.

If MBM5 works, enable the "sys log" feature, have it record to a text.doc every second. When it cuts off, go back in and look at the text.doc to see if there's any power flucuations or heat issues that may have caused the crash.

Well, I'll know when I get home and swap the PSU's. That won't take a minute anyway, so it's an easy rule-out or in type situation. I am still feeling like mobo because this is exactly what happens if you OC faster than your mobo can handle. This particular machine is stock, but it's the exact same reaction.
 
For those of you who said PSU-you appear to be right. I have swapped in a tester and it works fine so far.

Damn Sony for using proprietary components! The original PSU is only like 4" deep, so whatever I put in for permanence is gonna be literally up against the CDroms.
