driver_irql_not_less_or_equal

[d00d]

i bought some new stuff half a year a go:

asus p5kr mainboard
intel q6600 cpu
2x kingston hyper-x ddr2 800 mhz ram
xpertvision geforce 8800 gt sonic / club 3d geforce 7200 gs

and i used my old psu (Enermax EG465AX-VE(G)(FMA), 433 Watts), harddisks (1x 160 gb ide, 1x 320 gb ide) and i'm on windows xp. no overclocking, ram timings are set up correctly.

i often get a bluescreen which says driver_irql_not_less_or_equai, i tried several driver versions for my graphics card, chipset and so on. the error occurs with both graphics cardsi even returned the memory and mainboard to eliminate faulty hardware. but i still got that errormessage, sometimes 5 minutes after booting the system, sometimes 2 hours later.

then i switched to vista 32 bit and right after the 1st boot after installing the os i got another blue screen. right now i'm at my wit's end.

i was thinking of getting a new psu or mainboard to finally get rid of these ******* bluescreens. any ideas ?

my bios only provides the "load default settings" option but that doesn't help at all. i noticed during the last few days that the computer everytime crashes 5 minutes after i turned it on. thats very strange.
