Game crashing randomly, black screen

[anuvi]

Hi!

First time poster, long time lurker... I have been trying to get over my annoying game crashing problem with no results so I thought I might humbly turn to you and ask you guys for help, as a last resort sort of... I recently got a new computer, specs as follows:

Processor:  Phenom II X4 925, AM3 2.8 GHz 95W
Graphics card: Ati Radeon HD 5750 iceQ+, 1GB, GDDR5, 128-bit, PCI
Memory: Kingston HyperX 2x2GB, DDR2 1066MHz, CL5
Operating system: Windows 7 Home Premium 64-bit
directX 11

Problem is, that when I play the game it quite suddenly and randomly shuts everything down. I get most often black screen (once it was red, once light violet, once gray with thin stripes but mostly I get the black one) and the computer stops reacting. I have to reset in order to get my computer alive again. If I boot it, nothing happens, has to be reseted. I have checked with Everest that it's not about over heating and it's not about too much strain on the computer. When I look at the log Everest creates, there is actually no events what so ever to the time when the crash happens.

In the Sims2 Logs folder I have this:

So, being a complete noob in these things, is that " <<NOT FOUND IN DATABASE!>>" very significant and has it something to do with this crashing thing?

There is no difference whether I play completely "pure" game or have my cc and hacks on. There is also no difference if I run the game in XP Compatibility Mode or not. For some reason I can't set the CPU affinity to one core, I get a message that it is not possible.

I have tried to look at my graphic cards settings but, being the noob I am, haven't been able to come to any solusion what should I do with them. I have just resently  updated my drivers (yesterday or the day before). I have directX11.

Any ideas what's going on with my game? I would greatly appreciate any help and I hope I have provided enough information in order to someone get some sort of picture drawn. If you need anymore information, I will gladly give it to you. Thank you for reading about my problems and giving them a thought!

My guess? Overheating. Hard-lock is a driver or hardware malfunction, and "randomly" tends to imply a heat related issue. The other alternative is power shortfalls, if your power supply is not adequate.

Thanks for answering! I have been watching the temperatures with Everest while playing and they seem to be around 50ºC. I have never seen temperatures reach 70ºC. I have an extra fan and my graphic card is supposed to be running a bit cooler than an average. I also have a possibility to adjust my fans and at the moment they are set to run in medium. I think that temperatures around 50ºC during playing are ok? My power supply should be adequate (Antec's TruePower Trio 550W).

Oh, I'm sure there is a logical or reasonable explanation to my problem, I just wish I could figure out what it is. I had been thinking that the problem has something to do with my graphics card and the settings it has but I just can't understand the settings and what I should be adjusting in order to get a balanced and functional system. Well, I just have to dig deeper and google even more. ;-) But thank you for taking time and answering Pescado!
