My computer runs fine when warm and has been going for a bit..no problems what so ever. I can do restarts fine, shut it down for a bit and boot up fine, however, if I have turned it off the night before..it takes about 20 attempts to get it to boot up. Normally..first boot will boot right into Windows..but freezes after a couple of mouse clicks...then the fun begins. I have to hold the power button in to turn it off..and when I go to start up again..it locks during various stages of bootup. Sometimes it wont even turn the monitor on or start the hard drive, even though the power starts..I just get a black screen. Other times it may get to the memory testing stage, or detecting hard drive stage, or maybe one or two screens later and then it just stops..sometimes restarting itself, other times the monitor just goes off and once again I have to hold the power button in to turn it off. My best method of boot up is..when it locks, turn it off, leave for a few minutes. The longer I leave it, the further into boot up it goes. But if I leave it too long...it all starts over again.
Since this began, I tried leaving the computer on overnight. Thats all good, and if a warm night it is still going the next morning. But on a cold night..and if I have just left it..it will lock itself up at some stage.
So am totally frustrated..and not sure where to start. Sorry this post is long..but trying to cover any questions that may be asked.
Problem started after new hard drive installed. But prior to that..machine was locking at random..and old hard drive sounded sick. So replaced hard drive and these latest problems started. I loaded the bios disk when I set up the new hard drive..but when these problems started I set it back to default settings..no difference whatsoever.
The only thing I can think of is memory..but people are telling me they have never heard of memory not working when cold. But I am attributing other problems to memory as well. If I am running a game, sometimes the pc will restart itself if I have the game paused in the background, but have stopped to check mail or something. Game will normally work fine if I am not using other programs. However before I was able to pause in the background with no other issues.
Am running Windows XP on AMD Athlon 2600+. 1.92GHz, with 512mb DDR. I downloaded the latest NVidia drivers for my video card, and that side seems ok anyway.
Any ideas. This is driving me insane.
