Assuming that you're running Windows XP, you should have plenty of memory.
Your post is void of any real clues as to what may have caused the problem.
Have you installed any new software or hardware recently that may have caused the change?
If so give the details as to what and how it was installed.
I have an HP Pavilion 5300 series laptop. Two days ago, i noticed when i powered up my laptop, the blue windows screen comes on just before you make your choice which user you use and it "freezes" up; nothing, just dead! i've tried to press Ctrl,Alt and Del and nothing! I've had to do a hard reset by using a pin and press the reset button on the back of the pc. While the pc is on; the hard drive seems to be working; meaning, it's thinking to me. so, i don't think it's the hard drive. however, i'm not sure if it's the memory--maybe i need to up my memory(using 512mb ddr...can anyone help me??
I can upgrade hard drive and memory myself, just want to make sure it's one or the other.
Thanks for reading!
