Freezing while playing games, Sapphire HD 2600 Pro

Uhm, this is my old PC, I got 2 PC's, the computer is kinda old:
I installed Windows 7 on it because I had some problems with XP, was unable to find the right driver for the video card.

OS: Windows 7 Ultimate x32
CPU: Intel Pentium 4, 2400 MHz (18 x 133), Prescott
Motherboard: Foxconn 661MX Pro
Memory: 2x512 MB Geil & Kingston
Graphics Card(s): Sapphire HD 2600 PRO AGP, 512 MB, 128 Bit.
Sound Card: Realtek C655 @ SiS 7012 Audio Device PCI (onboard)
Screen Resolution: 1280x1024
Hard Drives: HDS728080PLAT20 ATA Device (Hitachi)
PSU: Green Power (never heard of this manuf name) it says it's 420W but I don't believe.

EDIT: I've ran Aida64 and went to Overclock tab, and I've seen that my GPU is overclocked O.O

Code:

Graphics Processor Properties	
Video Adapter	ATI Radeon HD 2600 Pro AGP (RV630)
GPU Code Name	RV630  (AGP 8x 1002 / 9587, Rev 00)
GPU Clock	594 MHz  (original: 600 MHz)
Memory Clock	495 MHz  (original: 400 MHz, overclock: 24%)

I never overclocked any hardware on this computer. Hum!!!!!!

Plus no WATTAGE'S anywhere. Voltages yes, temps, yes, watts, no.!!

Restore to original.

Alex you do yourself & us a disfavour by saying categorically the above yet quite clearly you are ...

I've noticed another thing, when I run System Rating, at "Direct3D 9 Texture Load Assessment" the computer freezes, so I can't get the rating done.
What Direct3D 9 is?; is it DirectX9?; Getting no sufficient power to run this feature (same with games that use this feature)?
Small games are working fine, like Fruit Ninja, Angry Birds, Big Fish Games, FIFA 09, Extrmeme Trucker...but when it comes to run MW2, the shit freezes, I think because the game uses this feature and because it doesn't get enough power it freezes.
Could be a faulty graphic card...I don't think so, because like a said some games works, never froze while surfing the internet, never seen artifacts & pixelations.

Your power P/S voltages are weak but never take what the BIOs says to be true, use a voltmeter to get true and accurate readings.
How old is this MB?
First thing you want to do is check the MB, look for any bulging or leaking capacitors on the MB, most times the capacitors around the CPU, memory slots and the AGP slot are the ones to leak or bulge.

I've taken a look on the MB, it has no leaking capacitors.
The MB it's from 2004, I think, old shit.
