HP W7 problems & Nothing displayed on monitor

Hewlett-packard / Pavilion slimline s3505f
August 22, 2010 at 12:17:45
Specs: Windows 7
When I turn on my computer nothing displays, moniter is idle and "In Power Save Mode, Press computer power button or any key on the keyboard or move mouse". The keyboard appears to be off but the mouse still looks fine. When I move it however nothing happens.
It started when I was browsing then suddenly my computer froze. So I held down the computers power button until it shut down. When I tried to turn it on however it froze when Windows 7 was "Starting Windows". I held the power button down again until it shut down and now it won't display anything. I've kept trying to boot back into the computer and one time it worked, and I got to the "Start Windows Normally or Repair Windows Start-up" but then it froze again. I've tried unplugging everything from the computer and replugging it back in but to no avail. I've also tried switching it with another moniter. I think it might be some kind of hardware failure?

Maybe a buildup of dust inside the case? I'm about to try to open it up.

dust build up is always an issue, overheating due to dust can cause these very symptoms.
so can a bad memory stick.
damaged disk files or sectors

blow out and or vacuum as much dust as possible. test the machine for sratup, but go straight into bios and check your running temps.
if the temps remain ok set the bios to default settings and reboot.
if the temps are running high, check which ones and attempt to resolve the airflow, cooling issues, if its the cpu, you may need to remove the coolerblock, clean the fan and the block remove all thermal paste from the block and cpu and then replace paste and cooler block making sure it is a good tight fit.
then see what happens

i hate computers!
but cant help myself....

I cleaned out the dust but I don't think it was the problem. I can't check the bios because nothing is displayed to the moniter. I may just take it to a technician.

Try removing and reseating the memory sticks to see if you have a bad contact there. If that does not help, try to run Memtest. I believe that Memtest86 is the latest and you download the ISO image and burn it onto a CD (obviously on a different machine), then you boot the machine with the CD in the drive. If it boots, that will prove that certain hardware at least is working. Run the tests (all) and read the results. If the test shows a bad memory stick, replace (with multiple sticks, rerun with one at a time to decide which is bad). If all tests OK you will need to test your hard drive. Try booting with your Windows 7 DVD and try a repair.

You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
