  1. I'd say that one cause is that the cpu is not seated properly, otherwise, the PSU may be faulty?
  2. I think my psu is faulty , its an i ball 250W only but is there a chance that my hard drive is faulty because i can't afford to lose my data , and how can i put cpu properly
  3. A faulty hard drive would not cause this...If you have not touched the CPU and it was working fine before, there should be no need to reseat it.
  4. IMO its PSU that causing trouble check it to your friends pc if it does same then its having problem :)
  5. Ok so now it conformed that my psu is bad , but i just wanted to ask i'm going to buy xfx ati radeon hd 5770 so which psu will be good for me to use 5770 and for other work , not like my iball cheap psu and one more qustion will my asus p5kpl am in be able to handle 5770 please hepl me .
  6. I'd say at least a quality 450w PSU. Your Asus P5kpl will 'handle' the card fine but you may not see too much improvement if your cpu's not up to it. What are the rest of your system specs?
  7. Intel core 2 duo E7500 @ 2.93 ghz
    ram - 2gb
    hdd - 320 gb
    gpu - intel g31 / 33 express chipset

    will 450w will be enough or its just ok and how is my cpu will it use the card will full efficiency .
