Try at least 512.
As for the machine freezing when it is too hot, it will, and it will, too, if it gets too cold. Other things to look out for: viruses, parasites, too many unneeded processes or programs running at start up...
Computer Freezes after it warms up?
So my brothers computer seem to freeze up at some pretty strange times. He has a E-Machine 1.4 MHz Celeron processor. We upgraded the RAM this summer to 384 in RAM. Has Windows XP Home.
They said it started happened after he canceled some big download he was trying to do. I got on the computer the first couple of times and I couldn?t really figure out why it would freeze. Sometimes getting on the internet, sometimes maximizing a windows. Finally it seemed like anytime I tried to stop the Windows Security Center it would freeze. (The computer would also freeze in Safe mode).
I finally decided to just uninstall SP2. My brother had downloaded it from the internet. I wasn?t worried because I have it on CD myself. Rebooted, tried a couple of open and closing windows, seemed to be ok. Left the computer that way, just wrote them a note to see if the problem kept happening.
A day later I called to see what the status was. Found out it doesn?t even turn on? Really nothing came up on the screen. I went over there today and it booted just fine. Probably about 5 mins after it had booted up, it froze for a second, then started to reboot itself (Seeing the bios and so forth). That goes through and then just a black screen (where the Windows XP Home edition would come up).
I turned off the computer, tried to get it to go into safe mode. It would then hang at different spots as it was booting up.
It then seemed like it had to be more hardware then software. So I unplugged it all, and took the cover off. Booted it back up, and it booted into safe mode. Was in safe mode for maybe 3 mins and it froze, had to turn it off.
I checked Ram in different stops. Same thing happen. I didn?t really know what else to test? I thought it was the power supply? Could be the hard drive, but that seems to boot just fine.
So I turned the computer off and left it off for 10 mins. Came back and booted it booted into Safe mode. Started the Starfield screen saver, it was probably on for maybe 2 mins and then the computer froze (probably about 5 mins after it had booted). It seems like something is hanging after it gets to hot? That is the only thing I can think of? The Processor has the fan going, but it is a little dusty? Would that cause it to hang?
I am just stumped on what to do? I really want to get the computer up and running enough to back up some of the files on the computer. Then maybe a reload of XP. But the computer doesn?t stay on long enough to back anything up.
