Computer crashing, confused.. help appreciated..

  [DELETED] 18:03 26 Apr 2006

Hey guys.

First of all my PC specs..

AMD x2 3800
PowerColor ATI Radeon X1800 XT 512MB
MSI K8N Neo4 Platinum nForce4 Ultra
2gb GeIL RAM
Hitachi Deskstar T7K250 NCQ 160GB
NEC ND4570 16x16 DVD±RW
Antec Sonata II Piano Black Quiet Case - 450w Smart Power PSU

I've got both my motherboard and graphics cards' drivers.

I've installed Sims 2 for my sister but it keeps crashing. First time it crashed when she was creating a family (just randomly, she had been playing it about 15 mins) and second time was when she went in to the neighbourhood screen. We managed to get the game in to one of the houses and I pulled all the settings down to the lowest possible and it was running fine. Just as a text I started knocking things up one at a time and eventually, of course, it crashed again.

Aside from Sims 2, 3DMark 05 also crashed too about 30-40 seconds in to the test.

Anyone know what the problem could be? From looking at my spec it's obviously not the Sims 2 or 3DMark are too powerful for my PC to run so I am really confused. CS 1.6, and Yuri's Revenge work absolutely fine..

Could it be my 450w PSU? I'm hoping not because I can imagine what a bugger they are to take out and replace.

There is also a blue and black wired thing coming from my case's PSU and I can't help but feeling it needs to be plugged in but I don't know what it is. From looking at the end of it (two holes) it looks as though it'd fit a fan header..

Also might be worth mentioning that since I installed the motherboard drivers there is a screen that comes up, inbetween the Windows XP loading screen and the Windows XP logon screen, that looks all crashy.. hard to describe heh..

Yeah I've got both my graphics card and motherboard's latest drivers. :(

if you have clone cd on your computer it will conflict with the security of sims 2 and will cause either problems loading or sims 2 to crash

I have Nero, but not Clone CD.

the blue and black wire sounds like the Protection circuit, which should be plugged in to the back of the PSU. Is it a Modular PSU?

Have you plugged in the power supply for the PCI-Express card?

I had a similar problem, with both of my computers, the first one the CPU heat sink was broke, and the processor was overheating I replaced it and haven’t had any problems; you may be able to download software to test the CPU temperature.

On my second one it was the DVD RW, it was slow to boot, or crashed before reaching the Windows splash screen, I removed the drives for the BIOS boot menu.

Hope this might help

if it is the psu it is easy to change, only four screws hold it in.

Suggest you do a disc check from my computer C:\tools\....

  [DELETED] 19:14 26 Apr 2006

Tried that, doesn't come up with any errors.

Did your computer Restart to check the Drive?
