Hi, I need my laptop computer to be working asap, and resolving this issue soon would really make my day. I have an HP Pavilion dv6324us. (specs from hp) There have been a few problems with it before, but nothing serious (wireless internet stopped working - probably the biggest other problem, but no big deal) When I turn the computer on, all of the lights light up but nothing shows up on the display. The fan runs at normal speed and then slows down (it did not do this when starting normal) after which it shuts off completely and restarts. This continues until I do a hard shutdown. (each 'cycle' takes about a minute) This problem came completely out of the blue. I was using the computer the previous day with no problems at all. I have not used any resource intensive programs (games, photo editing, etc) for a long time. I'm 99.9% positive I had no viruses or anything last time it was working ok. I have tried taking out the memory and harddrive and re-seating them, and unplugging the RTC battery to reset the CMOS, both to no effect. Any help or ideas would be greatly appreciated.

Had this same thing happen on an HP laptop I was working on. In my situation the problem was the RAM. The fastest way to determine if it is the memory is to pull one of the sticks and then start the computer. If your problem persists then pull that stick of RAM out and put the other one in. If your problem still persists the next step would be to try a new stick of RAM but before you go out unnecessarily buying memory you can confirm that there is a problem (or no problem) with it by running memtest86. Download memtest86 and burn it to CD. Pull one of the sticks of RAM. Start your computer with the memtest86 CD loaded Follow the prompts. If after a few tests you don't see any errors returned on that stick, remove it and repeat above on the next. If HP has a hardware diagnostic tool you may find it less intimidating to use than memtest86. Hope this helps. MJ

Nope, I tried that both with one memory stick at a time and just to be sure I tried putting in some old RAM I have, to no effect. Other things I have done: -I checked the power supply with a voltmeter, it is outputting the 18.5V it is supposed to. It could be possible that it can't keep up with the current demands but that seems unlikely. -The computer will not boot from a disc either. However, I could hear the DVD drive start up/begin to read the disc before it restarted if that means anything. Thanks for the help.

There have been many complaints about the integrated graphics on HP laptops failing at a much higher than expected rate. nVidia admitted there was a problem with their GPU. I don't have links but Google should produce some. Hopefully that isn't your problem, but?
