Having problems with your HP Compaq Presario SR1517CL (PX797AA) PC Desktop ?

My computer started freezing for no apparent reason and at random times. All scans came came back clean, and I had plenty of memory available. Now all of a sudden, when I turn it on, I have no video input to my monitor. Any ideas? Its a Compaq Presario desktop SR1517CL.


Answers :

I'd try playing with the graphics card - if it's a card and not on-board, try removing & re-inserting it. Also, try removing the card altogether and using the on-board video controller - if that solves it, the card may need to be replaced.

Also, try running a RAM check. You can use something like Memtest86 (http://www.memtest.org/): burn it on a CD and boot up from it. Even if you have plenty of RAM, a single broken bit can ruin the whole thing. There's also a scenario where you just have to remove and re-insert all the RAM sticks from the motherboard due to static buildup - it would cause the computer to not do anything when you press the power button.

If all of these still don't work, and you say you have absolutely no video output, it could be a problem with the power supply, processor or motherboard. The only way to check is to test replacements for each - replace the power supply and try turning it on, then replace the CPU and try, then mobo (though it's a lot of work).

Good luck

I've got a Toshiba Satellite Pro L300 that I'm trying to connect to my very old TV (16 years). I'm going through the VCR.

Any help would be appreciated. Oh, it go directly to the TV, I would need to convert the PC's VGA to coaxial. I thought it would be easier going through the VCR's RGB.
