Hope people can give me advice on this problem because it is absolutely puzzling me and I'm just about ready to throw my laptop out of the window. Recently i bought a new 1GB Ram card for my laptop because both Ram card slots on have a 256mb card i had to take 1 out and then put the new 1GB card in, so i upgraded to 1280mb Ram from 512mb. After a couple of days my system shut down automatically and restarted i thought nothing of it at the time and nothing else happened for about 4-5 days, then yesterday and today it has been constantly restarting yesterday about 5 times in 2 hours and then today about once every 5 minutes for the last hour. I think i my have a temp or power supply problem but not sure, I have been monitoring temps of the CPU and HDD and the they are higher than what they were before i added the new card there is not so much difference in the CPU about 2C the CPU temp is currently 45C and doesn't go higher than 50C but the HDD temp has skyrocketed to between 45-50C from about 38-40C so i am thinking the problem is temp and the power supply. If anyone has any thoughts i would greatly appreciate them. I will post my system spec on my profile as well.
