I have a HP Touchsmart 310 1100z which when I power on there is only a black screen and I hear the fans running. No HP logo or prompt to enter the bios-just a completely black screen.
I have tried:
1) The HP suggested reset of the bios to default settings (http://h10025.www1.hp.com/ewfrf/wc/document?docnam
2) Removing the hard drive, reseating the memory, unplugging all usb accessories
3) Used another power supply from another HP 310
4) changing the jumper on the motherboard from 1-2 to 7-8 and then back to 1-2 to clear the cmos
I'm about to remove the cooling fan and apparatus and reseat the cpu, but I'm wondering if there is anything to try before that.
I'm beginning to think it's a bad motherboard, gpu, or display inverter.
It's out of warrnaty, so if anyone has any advice I would appreciate it.
This seems to be a problem which has been listed in a dozen other posts with no real solution given.

Same issue. Took it to geek squad; total waste of money and time. Was told it was a 'hardware failure' but they could not specify what exactly was wrong with it. Would appreciate someone posting if they find out how to fix.

Took the cooling apparatus off, but I was unable to release and reseat the CPU. The graphics processor is soldered to the motherboard so can’t reseat that.
Don’t think it’s the inverter since a dim image would be present and the pc would boot and I would see it on the network.
A used motherboard was ordered off of Amazon, but someone else is taking over with this problem.
I’m thinking it is the CPU. On an old Dell pc I tried removing the cpu to see what happens when you turn it on. When I do, the fan runs, but there are no beeps and the display is black. So I’m leaning towards thinking it’s the cpu.
Other possibilities in your case may be:
1) A USB port with shorted pins (look inside the port).
2) A bad power supply board (connected to the motherboard).
3) Blown Capacitor on the motherboard
Finally, be aware that HP has Carepacks for out of warranty Touchsmarts (about $199), but they do not cover existing problems, I believe. So be careful about calling HP if you plan to buy a Carepack.
14 months old and dead in the water, this Touchsmart is not making me very comfortable with HP’s engineering skills.

I solved my problem with my 310- it was the CPU. Replaced with the same model AMD cpu bought off of Amazon.
Works fine now.
On my model 310 their is no video card to replace. There is video chip soldered to the motherboard.

I have had mine into the shop 3 times to get the display replaced. It is out now for the 4th time.
The laptop is practically unused - it is in the shop for repairs more than it is home being used.
I suggest - trash it - get something reliable. HP will just keep running you around and making you pay for repairs.
It seems to last just until the warranty runs out....hmmmm.
