i cant reinstall my os? windows vista reboot? pc problem?

[Joshua B]

I tried to reinstall my os on my laptop however it says that apparantly I have 248mb of RAM but it requires 512 MB of RAM. I dont understand this because my computer had 1 gb of RAM when i got it...i never knew that RAM could decrease... I have more than enough hard drive space, but I really need to know how to free up this RAM

p.s. could this also be why my computers currently running really slowly?

cheers folks

Hi,

Yes, a lack of ram will slow down the pc.

Check that the ram has not become loose in the slots.

The ram could be faulty or the motherboard.8-((

How much is shown on the screen when you originally boot up before you get to the windows loading screen?

Normally you should see the pc checking the ram in the bios as it boots.
