Why is my Computer FREEZING randomly?

Recently my computer has recently started Freezing completely, and the motherboard has to be grounded to shut the computer off, it has happened when just browsing the internet, its timing is very random, i can't find a link with any hardware to the cause of this problem, I have done many virus scans, and now I keep hitting dead ends with my searches, I cant find the problem to this, I need some suggestions to help me fix this before I take the PC to a store. I have made one link with it, but this does not explain the web browsing freezing, but it often freezes on the boot up of certain games.

PC Specs:
CPU: Intel Core i7-2600 @3.4GHz
GFX: Gigabyte GTX660 OC
RAM: 8GB @667MHz
MoBo: Dell Inc. 0Y2MRG

Thanks for Reading.

ok. lots of things can cause this... lets just start with the basics.

1) what temps are you getting (cpu/gpu/mb)? High temps can cause some of these problems. if you don't think the temp readings are right, Open the side of the case, stick a fan into it, see if the problem persists.

2) try a different psu. your powersupply might be dying. double check it.

3) this problem doesn't sound like ram breaking down, but lets eliminate that next. Pull all the ram but one, and run memcheck86. repeat till all your ram is tested

4) Pull out the gpu, and use the onboard video, see if the problem persists. your symptoms DO match a gpu dying. lets make sure this isn't the problem.

5) take the motherboard out of the case, make sure it's not grounding out into the case, check that nothing is behind the board. visually inspect the motherboard for dirt, stains and dust. if necessary clean the motherboard using 90% rubbing alcohol and qtips.

~at this point i'd say we've tested everything. if you still have the problem its likely the motherboard causing it.

I think Suggestion No. 2 is probably the factor here, I never thought about it, but I think it because I recently upgraded my GFX card which recomends upto a 500W PSU to operate, but I only have a 370-380W PSU currently, so I think I will Upgrade that, because I have been wanting to upgrade but I didn't think it was the issue. Thank you very Much, and I will let you know how the new PSU works.

I have Some new information, whenever I try and play specific games it crashes instantly on start up every time, this is making me doubt its the PSU.
