Hi guys. Hope you can help. I'm not exactly an expert with this whole computing malarky, but I do know a little, well, enough to change out parts, ordinarily at least. Anyway, I recently recieved an Advent ERT2250 laptop from a friend. But it only had 1 GB ram and a 70GB HDD. So I decided to increase the Ram to 2GB (Kingston) and the HDD to 320GB capacity (WD). As soon as I recieved the laptop, however, I decided I needed to downgrade the OS from Vista to XP. This was done without incident, and all was fine. Anyway, having recieved the upgrade components, I installed them without wasting any time whatsoever, assuming all I would need to do was insert the XP disc and reboot the PC. Alas, this is where I am stuck. I inserted the disc, and when I hit the power button, the disc spins, I think a fan comes on, but the screen remains blank. I tried discharging the power (using a method found on this board by removing all power sources and holding the on button, before replacing only the power chord and trying to turn on). Basically, I have come up with a blank here. Nothing seems to be working for me at all. Any help would be much appreciated. Cheers.
