My Laptop boots up perfectly and after about 3-8 minutes down the line whether I am working on the system or not ( whether the mouse is moving or not) it goes dark
Faintly I can see the screens in the background .I tried to log off and on and rebooted the system.
Does anyone have a clue
The problem is the graphic card. There are some guys who manage to resolder the ATI Chip on the card but the best thing is to buy a working one on ebay and replace the graphic card under the keyboard. Possible board part numbers 336968-001 or 336969-001 or 336970-001

I think this is a problem with the laptop's LCD display. To verify this connect the laptop to an external display and see if it resolves the issue. If it does then its confirmed that its a display related issue. Since the issue has appeared suddenly I dont think its a serious problem. May be just loose/disconnected connectors. Should be a 10 minute job for a qualified technician. If the external display too doesn't come on then its an issue with the graphics card and you may need to replace it.
You can directly do this with setup boot diskette (came with your laptop). There you'll find the option to format and do a clean installation of windows. For this, you need to configure CD-ROM as your first boot device and follow on-screen instructions after booting.(i am assuming that you've done the formatting and clean setup before)
Sounds like either the LCD or the inverter to the LCD is going bad you on. After it heats up thats when the problem starts. If your laptop is under warranty I would call HP Tech Support and let them troubleshoot with you over the phone either way they will probably replace the LCD and inverter.
By "where I want to go", do you mean going on the internet? If all you are getting is a blank screen, then you have the "about:blank" virus. Go here, print out the instructions, and read them well. Then read them again and follow them closely. At one time I had it on a desktop system and the instructions worked just fine.
Could be another issue dragging the data circuit down for USB functions. If you plug a USB device in with an LED on it does the light come in? If you have electronics or basic electrical knowledge also look to be sure the 5V supply is present. Ive seen Integrated modem/audio chips kill USB function as well as embedded controller chipset issues. Everything shows working in device manager? Try not mapping thru Modem and see if USB returns.. Yell back..
Star looking more closely at the surrounding environment. Is there other electronic equipment in your apartment that may be interfering with your laptop. Where do you set your laptop when you are trying to start it up at your house as opposed to where you set it up at work? etc....
Genuinely appears to be an environmental issue.
