2gb Patriot + 2gb Crucial both DDR2-800
Geforce FX5500 (looking to replace with a 8800 gt or g92 gts)
Western Digital 500gb Cavier
Corsair 620hx psu
Lite-On DVD writer
Vista Ultimate 64bit
and i keep getting BSODs with different errors:
IRQL_NOT_LESS_OR_EQUAL - i get this the most often ESPECIALLY when putting my pc on standby (as i click utton
MEMORY_MANAGEMENT - happens at random times, also while watching video
and also an nvidia error but its nonexistant after i installed correct VGA drivers.
i ran Prime95 for ~5hours with no errors (at least i didnt get any dialog boxes and the status looked ok)
Any help is greatly appreciated. any way i can check my hardware, etc. but i think there is no problem with that.
i can't run memtest because it says its not compatibile with 64bit OS, but i will try the 1 brand thing EVEN THOUGH my other pc which is a P35 is running the exact same RAM combo and it works flawlessly.
memtest shouldn't care about the fact that you are running a 64 bit OS - when you are booting up, make sure you have the memtest floppy (or CD) in the drive and boot from it.
Run memtest overnight at least and if you see errors, replace the bad memory. If you don't see any errors in memtest, run a checkdisk from windows on all your drives (it will do the checkdisk when you reboot).
Having the two brands of memory should not cause a problem (assuming that both need the same voltage) - preferably, put one brand memory in one channel.
