Hello! Welcome to TechSpot!

Whats the PSU?
may be an under powered stock psu.

i up graded the psu to a 500 w and allthe specs on the psu comply with the card

 

[dant4629]

ohhh by the way i've heard of problems with the chipset and some pci express cards can anyone give me info on drivers that fix this or am i just screwed

Maybe a fresh bios or chipset drivers are in order?
Intel® 915 Express Chipset Family
