Screen freezes

  Redlegs 01:38 12 Mar 2007

Hi there , have got ACER Aspire T 300 and just replaced the original " 248 MB of RAM " with two 512 Sticks , giving me " .99 GB of RAM " ie one GB. Within hours of replacing , computer now freezes after 15 - 20 minutes -- no response from mouse or keyboard ( both wireless ) or " escape " or " ctrl/alt/delete". Have to turn off and wait at least 15 minutes before power on again , then I get another 15 - 20 minutes before same thing happens. Have looked at PC's similar questions , but no joy . Any ideas ?? thanks in advance

hi redlegs,
did you get the correct type of ram,?
if so try installing one stick at a time
you may have bad stick of ram unlikely it would be both sticks though.

Put back the original RAM and take out the new.
In effect put the computer back to when you know it was working and see what happens, if the problem goes away, check the new memory could be faulty/wrong type RAM.

if unsure ram type is correct
put old stick in and go online and check

If there is a sticker/label or manufactures name on the original memory, post full details here as it may help if the new RAM the is wrong type.

Redlegs here , hey thanks for the prompt response
from the four of you.I have been suss of the new RAM installed but being the eternal optimist, and seeing it was working OK on test, I have given the original RAM to the lad who installed the newies. I can get it back in a couple of days.
Guess I will have to be patient.
Thanks again , Redlegs
Irony is I had this response ready , half an hour ago and just about to " submit " it , when the power went off again !!

Redlegs here and my problem fully resolved and want to share with your readers ,especially
" moorie " and "acxxxx ", what it was, in case it happens to someone else.My friend pulled it apart again and discovered a fairly solid dust ball had lodged in the little fan servicing the
"processor" , while giving the case a pretty decent "spring clean " when fitting the larger capacity RAM memory sticks.As the fan could not rotate , the computer operated normally till the processor got too warm and shut itself and the whole computer down .Of course the reason why the duration of the sessions I could get was varied ,was dependent on the temperature of the room ,which also dictated how long before I could fire it up again, -- ie when it had sufficiently cooled down !!! Well there it is -- the
" doover " is working perfectly , many thanks again to "moorie" and "acxxx " who attempted my rescue. I must say that acting on their advice I learnt quite a bit about memory and got quite a bit of useful info from "" and "" regards , Redlegs
