Solved: Windows 7 works for only 60 minutes then stops responding !!

[salam2009]

Hi,
I got this weird/annoying issue yesterday and here goes the scenario:
I could use my Windows 7 for exactly 1 hour then it stops responding which leads me to restart.
After restart, I get an error of boot manager corruption so I have to use Setup disc to fix startup issues since this option won't show up the second reboot.
Anyway, after fixing it and booting successfully, the problem comes back with the same scenario which made me think I have hardware issue.

I did the following so far with no luck
1) Checked the cables inside
2) Resetted CMOS to default
3) Restored Win7 to an older (working) version using Acronis

Here's my config:
OS: Win7 Ultimate x64
MoBo: Gigabyte Ex58 Extreme
RAM: Kingmax DDR3 4x4 1333 Mhz
GPU: nVidia GTX 570
CPU: Intel Core i7 2.8 Ghz
HDD: Corsair SSD 64GB
PSU: Gigabyte 1200 watt
AntiVirus: Kaspersky Internet Security 2012

So, any suggestions?
Thanks in advance

sounds like a timing issue with the mb and ram or a bad ram stick. have you installed all the mb bios patches for your mb there are a lot of them. try running cpu-z check the speed and timing of your ram..if need to change it in the bios and with 4 dimms you may have to bump the voltage up a little. try running memtest to see if your ram is fine...if it passes try running the system wit h2 sicks and see if the error changes. also use hardware monitor to watch your cpu temps and power supply voltages.

I didn't install any new patch for my mb since the new one is beta, besides that I've been using the machine for a long time without problems.
Regarding memtest, it passed without any error.
Also sometimes resetting bios to default solve win7 boot corruption while setup disc couldn't!
Do u think it might be cpu or mb issue that needs a replacement in this case?!
Anyway, I'll do more tests now. thanks for the suggestions.

Turns out the issue was on the SSD Hard drive which needed firmware upgrade and that's what solved my problem!
Thanks anyway
