Can lack of power cause blue screen crashes

How likely is it that regular video driver blue screen crashes are caused be an insufficient power supply?

Thanks

that sound like memory more than power supply, have you tested you memory?

Yes i have done 2 memory diagnostic checks and both have indicated no problems.

what exactly is happening for you to say the video card driver? starting a game?

Playing a game, watching tv. Occasionally watch videos in media center. Even on one occasion playing an online flash game.

have you tried updating the driver?

Yes several times. I have also tried them from other sources and tried older versions. The problem exists. I have been told that the problem could be caused by the fact that my power supply is not powerful enough. I just want to know if it possible that an insufficient power supply would cause blue screen crashes because if not i can eliminate that as a cause.

list your system specs

in my experience when a power supply goes the drives and so forth do not work right and towards the end you have hard time just booting. i should know, it just happened to me it died over 1 month period of time, but i never had blue screens during that time

AMD Athlon 64 X2 4800+
Asrock AliveSata2-glan M/B
2gb DDR2 4200 Kingston Ram
500gb Seagate SATA HDD
150 Seagate IDE HDD
Lite-on DVD DL RW
Hauppauge Nova T500 tv card
ATI HD 2600 XT (GDDR4 version)

what size power supply? also, what version of windows and what chipset driver are you using?

Its a 400W. I think its just a generic brand. It came with my colors-it case. I am using vista home premium x64 and ati catalyst version 7.10.

you didn't install your chipset driver?

at 400 watt that is a little small for that system, i would get bigger one

spend a little money if you can afford it and get nice power supply

Sorry i dont know what my chipset driver is? How do i find it out? I did think they 400W was a bit small but could understand why it would cause blue screens

well with what you have in your system there is not enough juice to go around, so like for instance if you select to use the tv card and it goes to draw power that is not there it crashes. as far the chipset driver look at the asrock site for the latest on it

i would make sure you have things backed up in case the power supply does go

The asrock website lists all the individual drivers for sound, lan etc and i have got the latest version of all them. Here's the link: ASRock Motherboard - Product - ALiveSATA2-GLAN - Download

The thing i don't understand is that my secondary hard drive has xp on it so i can boot from that and i dont have any problems with blue screens in xp. just vista. Does vista use more power than xp?

no, that is telling me it might be driver related to 64 bit vista
