Is the laptop an HP DV 2000, 6000, or 9000 series? If so you could be one of the many afflicted with a problem that caused many HP laptops to go poof. There was an issue with these series of laptops motherboards causing the screen to go black, and then not power on. There was a recall that made the manufacturers warranty a year longer (from 1 to 2 years) but that has long since passed. Since it is the main board of the computer, it's a several hundred dollar repair and is typically more expensive to repair than it would be to buy a new laptop.
Regardless of whether or not this is your issue, I would recommend re-seating the RAM or having someone who is familiar with computers do this for you. Basically by removing and re-inserting the RAM in the computer you ensure there is a snug fit as this could cause a similar problem.
In some of the forums, it has mentioned that the windows update could corrupt the video driver. So try uninstalling the video driver and download the latest video driver from website and install it. This must resolve the issue.
I have a smilar problem, with the ATI enabled the laptop black screens on startup.
If you disable the ATI x600 in Device Manager (using safe mode) the laptop works fine as the ATI is not being used.
Solution is to replace the ATI x600, which unfortunately is a specialist job as this is soldered directly onto the motherboard. Or replace the motherboard.
I have located a company in Manchester (called CRM) that repairs HP computers, and they can repair/replace the ATI for around £175, or replace the motherboard for about £250. Replacing the board gives you a 12months warranty. add VAT to those figures. There phone number is 01618881232, I have found them to be very helpful.
I had the same problem for a year or so. I used vista in the meanwhile, but after a 3D bug I got upset and decided to try fix this bug, finally succeded in it. I'm sure it has something to do with the memory, but still there's a mistery........
The solution : It can be a little wierd, the softwares i used are : ASO - Advanced System Optimizer 2.2 and Mobility Modder 1.0 Final.
Step 1 (ASO) : In the windows optimizer at the System Performance #2 I turned on the : Improve Core Kernael Performance Enable Large System Cache (I made the cache size 1,024 - not sure if this was necessary) Theese options were to force the system to write the swap on memory instead of your HDD
Step 2 (Mobility modder) : First download a new Catalist Driver from anywhere on the net, then the modder from :
