Ive been recently dragging my old sytem kicking and screaming into the 21st century with some very much needed upgrades,
I repalced my ancient E2140 with a Q6600 (i know it's also old but im skint )
upped my Ram from 4GB to 6GB unfortunately my mobo (Asus PQ5L Pro) only supprots DDR2 which is annoying but still.
then i threw in a Sapphire 6870 to replace my old XFX HD 5450
straight forward enough, or so i thought, since putting in ther new card installing drivers andso on, ive been getting random BSOD's and crashes, played BF3 last night for about 2 hours fine, put it on for 10 mins this morning and my system reset itself, ive already unistalled the drivers (from AMD.com) and installed the same drivers but form Sapphire's site, made no difference, im worried that my PSU is not handling the new card well it's a CIT colours 550w gold.
any help would be greatly appreciated.
I think your PSU can be the problem. Those CIT PSU's are some chinese brand. Your PSU could handle the E2140 ,4GB RAM and 5450 , but now all your components need much more power Q6600, 6GB RAM and 6870.
