I use the computer during normal downloading the computer automatically switches off as though i just unplugged it I changed all the memorys hardrives etc and the drivers are all updated and no explanation marks by them I also have alot of problems like it is very low on memory but has 1 GB 400 MHZ memory sticks a pentium 4 3.2 GHZ cpu with an a-BIT lga 775 motherboard. I changed the mother board aswell seems to run a little better but not fully. I even reved programs down to just windows and no better. The other I thing is the floppy disk drive did not work in an amd processor board 754 and the elite groupe 775 board which does the same problem but worked in an a-bit
if any one could help I would be grateful

many thanks

Sounds like the case and the power supply.

I've seen thermal issues where under load the CPU and HDs generate heat, and the CPU gets too hot and the MB will shut down the system. The solution there would be to add more fans to the case. You might try running the case with the side panel off to see if it helps.

It could also be a flaky power supply that is failing only under load. If you can borrow a power supply and subsititute it in that migth help.

I totally agree with the other post regarding the heat. Also check to see if there is too much or too little thermal grease between the heat sink and P4.

I did actually had a problem in 2004 where a capacitor broke off of a memory stick. I was getting odd lock ups here and there like a thermal issue, like the issue would not show up until enough load was put on the system. I repaired the memory stick, but still had the problem. I replaced my proc (a P4 2.8E) , and have been fine ever since. If you have a compatible P4, and tried all the other items in the second post, swap the 3.2 out and give it a whirl.
