Hi guys,

I've had this problem with my computer. Every time i play a game my whole system crashes and blue lines come down the screen, it happens about 10 - 20 minutes into the game. Thing is this happened about 6 months ago, one day when it crashed i couldn't even turn it on so i went out and bought a new Motherboard, installed it and still wouldn't turn on so it wasn't the motherboard. Then as i was playing around with the wires it turned on (I had no idea what i done) and the computer worked for a few weeks until it happened again, this time i took out a stick of memory and it worked again. So i went happily playing games for about 5 months without issues when it happened again today while i was playing New Vegas. I don't know what it is, I'm starting to think it's the graphics card. I'm really not sure as it worked for 5 months after it wouldn't turn on.
I'm just confused at what it could be, It's definitely not my monitor. Should i go out and buy a new Video card?


I'm out of ideas and not a very hardware savvy guy.

  • It's the watts we need to know not the voltage. Read More

  • You can't change them, the PS wattage is whatever the mfg made it. If it is a 360w PS it is definitely to low to run that card with a heavy load. I would recommend at least a 700w PS. I play World of Warcraft at the highest possible video … Read More

What power supply has it got in it? You will have too have a look at it's label!

It could possibly be an overheating problem. Grab GPU_z and open it whilst the card is under load.
Record what the top temp is.

It's not an overheating problem, I've checked.

I bought a new PSU about 6 months ago actually, What would i need to check for?

What make and wattage is it and what spec is your PC?

It might also be a good idea to inspect the motherboard to see if any of the capacitors to see if any of them are domed or leaking!

All the wires,

I want to add that i was playing Minecraft today for about 5 hours and it didn't happen, It seems to only happen on graphics heavy games.

The 8800 GTS is quite a power hungry graphics card so I need the info on your power supply!

115/230v, i currently have it on 115v at the moment. Is that too low?

And this is what Xfire says it is -
Processor:
Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz (2 CPUs), ~2.4GHz

It sounds like you are closer to your answer. IMO it is definitely either your PS or the nVidia card. RIK is right the 8800 sucks a lot of juice, when I built my gamebox I originally had 2x9600 nVidia cards in SLI. I had to up my power supply from a 700 to a 1000. But when researching why my system was crashing due to lack of power, it would just completly shut down. I am leaning to the video card especially when you say that it happens during heavy load. I currently run an ATI single 1gb card and have found my core temps have dropped substantially. The prices have dropped on high end cards these days so either way you'll definitely improve your situation with a new card and you will have your answer.

The watts are 165w and 360w. I'm not sure how i can change them.

You can't change them, the PS wattage is whatever the mfg made it. If it is a 360w PS it is definitely to low to run that card with a heavy load. I would recommend at least a 700w PS. I play World of Warcraft at the highest possible video setting (Ultra Mode) and with the 1000w I never have had any problems. The deal is you can never get a PS with to high a voltage, if you are a gamer and it sounds like you are, then I would definitely replace that PS and would consider the VC as well, if it fits in your budget. I bet all of your issues would be solved.

OK, thank you guys!


Thing is i don't know why it worked perfectly for 4 months then started acting up again. I'll buy a new Video card and PSU soon as they're not too expensive.

Sorry I meant to say wattage not voltage in the above response. I wish you well and I hope it all goes great for you. BTW when you deal with any type of hardware issue, intermittent problems are quite common. The fact that it worked for 4 months without incident is really not that anomalous. Either way I hope you get it all solved with the recommendations I have suggested.

Power supplies do actually age, especially when run often at or close to maximum output. The closer to the maximum they are run the hotter they get, the hotter they get the more rapidly the components age.
