Friend's PC keeps crashing

[EmSixTeen]

I've no idea about this, but I may as well ask here if anyone can help:

 

 

]After playing a game for 10 seconds, my monitor flickers, freezes and parts of the PC must just shut down (more than likely the graphics card). Have to just hold in the power button till it goes off.

 

This happens for no reason i can find. Drivers for graphics card sound card etc are fine.

 

 

somebody mentioned looking here about the graphics card sharing a port with other hardware.

 

I can't make much use of it so here;

 

 

Specs:

 

Via KT8 Pro lite mobo

AMD 3700+ 939 2.2ghz clock

BFG AGP 6800GT with latest nvidia drivers - 1GHz, 350mhz, 256mb

 

2x1GB Crucial DDR 400 pc3200 DIMM

SATA DVD drive

IDE 80GB Maxtor HDD

 

This may be the problem-

 

LG L194WT LCD Widescreen 5ms 300cmd/s 5000:1 contrast ratio at 1440x900 antive resolution -problem only occured after this monitor.

 

Generic 350W Tsunami PSU

 

terrible generic case -both case and psu from late 2002

 

I have reformatted hard drive since getting monitor etc.

 

I think it's a power issue but I'm not sure.

 

The monitor is connected to a mains plug, and is currently on Digital output from the graphics card.

My old monitor,a  brick 17" CRT, used analogue so is the new digital beast causing too much stress for that awful old psu?

 

Is it my BIOS settings? I've been looking through them and can't find anything out of the norm, my brother switched the graphics card to a direct power source form the PSU, and still the porblem has been getting worse.

 

The graphics card is 2nd hand, and overclocked obviously, so it may be dying

The screen will do stuff like this:

It could be the card dying like he said, but I have a very good feeling that it's the power supply. Since it's 'Generic', it's probably pretty crap.

 

I suggest trying the PC out with another PSU with a decent wattage from a good, reputable brand .

Could be heat issues. Run a temperature monitoring program. Get soemthing like rivatuner or atitool and run the game in a window. That way you can monitor the temps while in game. Rivatuner does have an in-game OSD setting, but it's alot easier to just run the game in a window. I doubt it's a PSU issue because that would appear right after starting a game, not 10 minutes after.

 

Also, maybe take a screeenshot of the IRQ tab in that window you posted.
