Counter-Strike Source Crashing with No Error Message

I have been very frustrated with Windows 7 as ever since I installed it my CS:S crashes with no error message anywhere from 2 minutes - 30 minutes of playing.

I would love any solutions on how to fix this or anyone having similar problems.

I've downgraded drivers, upgraded drivers...nothing fixes it so far.

I've verified game files, defragged, run as administrator and tried almost all possible combination's of CS:S settings.

Here's my specs:

CPU: Intel Core 2 Duo 2.99Ghz
MOBO:Abit AB9 Pro
Graphics: PNY Nvidia GeForce 9500GT 1GB
HD:80GB Hard Drive
RAM: 2x1GB DDR2
OS:Windows 7

Nothing is overclocked or overheating, RAM has been tested, tried plenty of different Video card drivers and my hard drive has been scanned for bad sectors with no errors.

I was havin trouble with my COD MW2 also crashing. Come to find out, I changed the resolution in-game to same as my desktop, and whoolah, no more crashing. Beings CS is so old, it may not support the widescreen resolutions.
