Starcraft System Crash

I'm using Windows 7 RC x64.
I regularly play starcraft over UDP on my friend's LAN, as well as over Hamachi VPN.
This has happened twice now, where about 15minutes approximately into any game, my game completely locks up and I cannot Alt+Tab, Ctrl+Alt+Del or use any other method to exit the game.
The only thing I CAN do is a hard-reset.
On my friends screens, it's shows me timing out (via the "Drop Player" screen that pops up as soon as my system freezes).

I've played StarCraft extensively in Windows XP and Vista and NEVER had a problem like this.
I'm using 7 RC x64, like I said, and am using a Lenovo ThinkPad (specs below).
This has happened twice now, the first time I thought that Hamachi had dropped the connection. However, this time I was playing over the local network and the same crash happened.
It seems random, the in-game music keeps playing, my mouse freezes where it is and my entire system can't respond.

Quickly checked the Event Viewer under both Windows Logs > Application and Windows Logs > System and didn't find any information at the time of the crash.
EDIT: I will be monitoring my PC's temps in case it's hardware related.
I run TPFanControl to dissipate heat during 3D intensive games (Mirror's Edge, Mass Effect, etc.) and have no problems with GPU/CPU temps (I monitor them in-game using RivaTuner).

I've run StarCraft in both compatibility mode with Windows XP SP3 and without.
I was playing around with the compatibility options because of the color issue StarCraft seems to have (inverted colors, 8-bit colors makes everything look like its on acid, etc.).
It has crashed both running with and without compatibility options. And I am running the latest StarCraft patch, 1.16.1.

It has happened three times now.
My friends computer uses Vista and has had no problems like this ever.
And like I said, I've run it under XP and Vista myself, never any problems crashing.

My DirectX is up to date so I doubt that's the issue.

Just installed Age of Empires 2 today, happened while playing SINGLE PLAYER.
This is really frustrating.
Why on earth would older 2D games cause Win7 to choke like this?
Very frustrating and confusing.

Well, I'm changing drivers every few weeks so I know that with at least three sets of drivers, StarCraft still crashes when playing over LAN. I doubt it's a driver issue, every other game on my computer is stable.

I've used Forceware (via modified INFs @ laptopvideo2go) 181.22, 185.68, 185.81 Vista x64, AND 185.81 Win7 x64.
Currently using 185.68 Vista x64.
All "important" updates are installed via Windows Update.

I read on vistax64 forum that games may freeze because of faulty RAM.
Maybe memtest86 wouldn't be a bad idea, just to be safe?

yeah it can be that...
another thing to check is that if this happens if you play extensively in single player against many AI... (not campaign, i think its called skirmish...) and see if this happens...
if it does not then it might be the network driver...
whats is bothering me is that AoE 2 is not working either...
so bad mem is the most probable cause....:)

Ran memtest86+ v2.11.
50 min later and no errors so my memory seems to be functioning.

In relation to StarCraft and AoE:

• StarCraft would only freeze during LAN games -- I have played full games successfully (4v4 with 3 humans on map). However, every once in a while, five minutes into a match it crashed
• AoE, so far, only crashes during certain points in the single player -- today, it was crashing in a specific tutorial map. Hardly any AI on the map.

Still no closer to an answer...
To be sure, I downloaded DirectX 9.0c Redist for Software Developers and re-run the dxwebsetup from DirectX End-User Runtime.
Didn't make any difference.

EDIT: Sorry to anyone reading this thread, I'm not much help.
EDITEDIT: I'm seriously considering rolling back to Windows XP...
