Ok, this is a little long and detailed, so I apologize... I'm just trying to get a definitive answer before I decide to shell out some $$.

I have a custom home-built PC with 512 MB DDR RAM, a 1.4 Ghz Athlon, an ECS Elitegroup Mainboard K7S5A, a Geforce 2 Pro vid card, 3 sys fans, 1 very noisy cpu fan w/ very large heatsink (not sure of make/model) all running on Win98se.

Well, my comp started restarting a couple days ago all by itself. To make a long story short:
I found out that my CPU fan was not working. I checked the BIOS and my sys monitor said my CPU was at 104 'C!!! I don't know how long the CPU was at that temp or how long the fan was not working. Needless to say, I shut the system down, and then fiddled with the fan until it worked again. (I plugged it into another fan plug on the MoBo - it worked - then back into it's original slot - it worked again).

So Now, My computer starts up Windows when it feels like it. Sometimes it works and sometimes (most of the time) it doesn't. When it doesn't I get errors like the following:

- upon reg startup, blue screen w/ "an exception OE has occurred at 0028:C0000048 in VXD ---." followed by a black screen saying "While initializing device CONFIGMG: Windows protection error. You need to restart your computer."

-upon Safe mode startup, a black screen w/ "While initializing device VTD: Windows protection error. You need to restart your computer." Then it shuts OFF on it's own soon after.

-upon 'step-by-step confirmation', it goes through and loads everything fine, gets to my last driver "LMOUSE.VXD" and hangs after running it.

The computer loads up DOS fine, and never restarts from DOS.
I've checked the BOOTLOG file and the only thing that fails to load is "ndis2sup.vxd"
I've run MANY scanregs and scandisks (w/ a full surface scan on 2 occasions) and everything checks out ok.
Here's the kicker, WHEN Windows decides to work (which has happened 4 times since the beginning of this whole episode), If I leave it alone to sit at the desktop and do nothing, the comp stays on indefinitely (hours at a time), but as soon as I start to use applications it will restart without warning in anywhere from 5-30 minutes.
Like I said, the fan works now and I have the cover off. The CPU is at a 'cool' 48 'C or thereabouts.

So... what's wrong? In my opinion, the CPU is fried (at least partially) and I need to buy a new one. But, I want to make absolutely sure before I put down the $$.

Are these symptoms of a damaged CPU? or could there be another problem? Is the MoBo damaged too? How can I tell?

thanks in advance

-Matt
