I have a problem with gaming.When I play a resource demanding game like crysis my pc freezes.This happens after a period of 3 to 10 minutes.When I play a game like Warcraft 3 Frozen Throne it does'nt do this.I am in desperate need of help.The exact description of the 'freeze' : Screen loses power (goes into power save[exactly like when screen is on but not pc]) then computer sound continues to play but in 2 second loop ( tik-tik-tik-tik) and then it just keeps on doing this until i reset it.(power button doesnt work - need to use reset button )[and in restart windows does not ask if i would like to boot into safe mode)
My NEW system specs:
MSI K9N Neo V2 Motherboard
AMD 64 X2 5400+ CPU
2 Gig 800FSB Ram ( transcend )
NVidia Chaintech 9600 GT 512 mb ddr3 256 bit GPU
Seagate 500 gb Barrucada Sata 2 drive
550 watt Gigabyte superb Power supply
Windows Vista x64 Ultimate edition
I've got the following cooling :
3 ball bearing case fans.
1 Hdd cooler.
And my entire systems temprature never exceeds 45 degrees celcius as a maximum ( usually runs at 35 - 38 degrees under load)
What I have done to try and fix this and have not yet succeeded :
First : Old PC specs :
MSI K8N Neo V3 motherboard
AMD 64 3000+ CPU
1 gig 400 FSB Ram
Nvidia chaintech 9600GT GPU
Western Digital 160 gig IDE HDD
A open 400 watt power supply
Windows XP Proffesional SP3
The following things I have done :
1. Bought all of the New system hardware except for the GPU
2. Exchanged the GPU at suppliers ( checked if GPU has different serial number and ensured they did not give back the old one)
3.Uprgraded to windows Vista.
4.Changed Bios setting of motherboard back and forth between optimal and fail-safe defaults.And mannualy disabled any performance enhancing bios setting)
I have worked with computers for the last 12 years. I have never ever encountered any situation like this.
PLEASE DO ADVISE ANYONE , I REALLY NEED SOME EXPERTISE ON THIS
First, I would go to the Nvidia web site and download and install the most current vga driver for your system.
If that does not help, then, perhaps try their latest "beta" driver.
Next run some tests:
Memtest 86+ for several passes to verify that all ram is good.
Prime95 for a while to stress the cpu ram and cooling system.
Take the side panel off and test with a house fan directed at the innards. If you do not get the problem, then case cooling is suspect.
Well, seems you've covered everything, except maybe one thing: faulty home circuits?
It's happened only one, and about 10 years ago working for a LAN team, one of our VPN users kept screaming about random reboots/blue screens, so we went through the exact same thing you did; chance every component one by one and formatting.
Didn't fix the problem... I can't remember who thought of trying out a UPS, but that worked. Massive old 1400 UPS fixed it all (only model we had at the time)... he hated the noise it made, but it kept him working heh.
My ATI X800XT does the exact same thing when playing Diablo 2 when the indoor temps go above 77F or so. When I opened the case and put a floor fan to blow directly on the card, the problem stopped. So, it could be a heat problem.
Your original post did not include a sound card in your specs.
Were you using onboard sound, or a sound card?
Some sound cards have had problems with vista drivers.
Onboard HD sound is quite good these days. I would try it for a while.
Thinking a bit more about this, it sounds more like a power problem to the vga caed.
The vga card will use more power when it is pushed to the max. If it does not get what it needs, you will get strange results like yours.
The power comes both from the 6 pin pci-e connector, and also from the pci-e slot.
On your mobo, is the vga card inserted into the primary slot which should be getting the full 75w spec power?
If your psu is modular, are the vga leads secure?
Can you try a different plug for the pci-e power lead?
I can find no info on a gigabyte 500w unit.
Is it possible that the psu is defective or marginal? Your old 400w unit might have been giving the same symptoms because it was underpowered.
Can you try a different PSU?
