Computer restarting during some gaming on Windows 7 and a GeForce GTS 250. Could be power supply?

I think I have an issue with my power supply but I have little knowledge of it. I know enough to install hard drives, video cards and even transfer a mother board to another case. I know how to physically replace a power supply but I'm not sure if I gotta change some settings on the BIOS or whatever. The one I have is pretty old and I think it's causing the problems.



I used this one program CPUID and these are the results

Guess the main question is, do you just swap out the power supply with the new one and what do you guys suggest the voltage on it?



I'm running a Pentium Dual Core 2.50 GHZ, 4 GB ram and a 32 bit Windows 7 Home Premium. Can't remember what type of motherboard exactly but I do know it's an ASUS.Computer restarting during some gaming on Windows 7 and a GeForce GTS 250. Could be power supply?
If it only happens during gaming then the most likely culprits are buggy video drivers or a bad power supply. It's almost certainly the latter if you hear the psu cutting out, or the fan speed changing when the reboots occur.



Yes, you'd just disconnect everything from the old psu and swap the new one into place- only takes about 5 minutes with a screwdriver.



For a GTS 250 a 450W psu is recommended, so get at least 500W (or a 450W from Corsair). Anything higher is just allowing room for future upgrades. But there's usually a big price jump above the 500W mark, as many 550-650W units are SLI/Crossfire certified, providing two PCI-E power connectors for video cards. Great if you have dual cards or a single older power-hungry card that requires two connectors- like a GTX 260, Radeon 4870 etc, Radeon 5850 etc.

If your computer is crashing only during game play, i would recommend checking out your drivers are

up to date to start. Look to make sure your power supply can power your video card and computer Accessories.

I would check the fan on your video card make sure that is working, as this card tends to run hot and the fans on this cards tend to go. I have had to swap 2 pny gts 250 1gb ddr3 video cards cause the fan on them kept dying on me.

Finally got tired and just when i got the new card i went and took out the cover from the heat sink on the video card, i took the heat sink out, cleaned it and reapplied artic silver 5 and replace the thermal tape, and reattached the heat sink. Left the cover out with the fan out and instead i used this fan instead,

I took this apart and just kept the fan and switch part. this fan sits on the heat sink just fine and instead of having it being power by the graphic card, i hooked it up to my mobo.

This worked for me and stopped my PC from locking up cause my video card kept overheating, now im able to play MW2 with no problems.Computer restarting during some gaming on Windows 7 and a GeForce GTS 250. Could be power supply?
Can u please specify the model of your power supply? Besides having a high wattage power supply, I suggest knowing how much current does your psu drive on ur +12v rail. Google said that gts250 requires a PSU with min 400 watts with a current rating of 30Amp or more on the +12 rail.



If for instance u have a 500 watts PSU with only 22amp then ur system will shutdown or worse case ir PSU or even motherboard will short out. to calculate the current rating on ur +12v. Look at the power at ur PSU table and look at the power under ur +12v1 and or +12v2 and divide it by 12.



Example, i have a gigabyte superb 550p.

under my +12v1 and +12v2 i have 360 watts of power, the other 190 watts is driven to my power connectors and motherboard power. so....



360/12 = 30amp

meaning i can juice up any GPU which requires 30amp or less, (my 9800gt requires 26Amp so im good to go) anything above that would hurt ur PSU and even ur pc. Hope it helps.
