hp z600 wont turn on after I turn it off

Q: hp z600 wont turn on after I turn it off

I got hp z600 and i got geforce gtx 1070, I bought a power adapter 6 pin to 8 pin. I have the issue the PC will turn on and works fine but when i power it off and want to turn it on again it wont turn on at all. I have to unplug it and hold the reset button for few seconds then I plug it back again and it turns on. No it seems it is dead 100%. What can it be? too much power consumption from the video card? I got other hp z600 with gtx 1050 no external power required and it works great. Any suggestion? Thanks

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

Synopsis: PSU died, replaced PSU with different model, system boots to bios successfully but does not recognize any devices in SATA ports, nor do those devices appear to be getting power. Now can't even get to BIOS, entire PC flicks on and off repeatedly as soon as I turn the PSU on regardless of whether I hit the power button on the front of the computer.

System Specifications

Original PSU that died: SeaSonic M12II 750 SS-750AM 750w PSU
CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz
GPUs: ASUS 670 non-top version, SLI (2x)
MOBO: ASRock Z77 extreme 6
RAM: Mushkin Enhanced Blackline 8GB (2 x 4GB) SDRAM DDR3 2133
Optical drive: Sony AD-7280S-0B 24x SATA Internal DVD+/-RW Drive
SSD: SanDisk Extreme 240GB SATA 6.0 Gb-s 2.5-Inch (OS is installed here)
Storage drive: Western Digital Caviar Black 1 TB SATA III (This was not connected when power supply died)

Detailed explanation:About a week ago my PSU (Seasonic 750w) died randomly while the computer was left running in sleep . I RMA'd the dead seasonic. In the mean time I happened to come accross an extremely good deal on a new PSU, so I bought it (Thermaltake smart m850w PSU) to have a backup and to get my machine working again.

I hooked up the new PSU to GPUs, CPU, fans, ATX power connector, and to all of the SATA devices, (the SSD, the HDD, and the Optical drive). I made sure to connect the data cables to the SATA devices in the same configuration they were in when working properly. The computer boots suc... Read more

A:PSU died, new PSU, bios wont recognize SATA devices, now wont turn on

I had a similar problem when I had an Antec PSU die on me. After I replaced it, my Biostar mobo's BIOS would no longer retain settings, and both my Pioneer DVD burners were completely dead. Not recognized in the BIOS, they would not acknowledge any discs inserted, nothing worked. I also started getting BSODs pointing to a corrupt BIOS. Replacing the burners didn't help. Putting the Pioneer burners in a new machine didn't work.

It turned out that the dying Antec PSU had wrecked the Biostar's BIOS chip and both Pioneer DVD burners. Replacing the BIOS chip was more expensive than buying a new motherboard, and reflashing the chip wasn't possible because the flash utility told me I already had the latest BIOS version. I ended up trashing the board and buying an ASRock board and Samsung burners.

If you get a new motherboard (or try another known-good working PC), and you connect your present SATA devices and they don't work, then the dying Seasonic may have burnt them out, too.

18mth old pc. Wont boot. But is temporamental. Sometimes will turn on, make noise, and the dvd drive can open. Other times wont even power up or even the odd time i get to the american trends black screen with some commands like f2 for SETUP , f8 bb popup. Also noticed it said checksum bad

My girlfriends pc this is. It happened when she was using farmville. Got the bsod. PC was working really amazingly beforehand like brand new. Very little software, on it, and no music or movie downloads. No file sharing. Satisfactory AVG etc

A:Newbie bsod. Wont boot, wont even turn on most times, but does sometimes

If I leave it alone for a few hrs, the system might seem like its going to work, the on switch goes blue lit, theres the normal beep it makes, the three lights on the keyboard flash, then i get packard bell screen for split second which gives me options like enter BIOS, but that scares me. Then it will go straight to the American Trends page i explained earlier and wont go further

Then if you switch power off again and see what happens, it may not even power up next time, no blue lit on, a split second of fan noise then nada. Or it may have nothing happen except you can hear the fan running and the dvd drive can open

Of course she cant find her vista disc!!! We will find it 2moro somewhere though. There is no important data on the pc so if it was possible to reinstall vista I would just leave it in to get fixed. I got quoted 25 pounds.

Can anyone help me out or have any clue. My brother had a problem last month with a firefox update which gave him similair trouble. But lucky for him, it resolved itself after 3 days of turning it on/off and hoping for the best

Hi, I have recently recieved my HP Split X2 back from HP last week because the docking station would charge but the computer would not and now it's the opposite. I turned on my computer it was working fine, I plug it in to charge and i notice that the battery icon didnt change to charging so i unplugged it and plugged it back in and nothing so i undock the computer and that charges just fine i place it back and next thing i know it shuts off on me. i press the power button and nothing but when I hold it down the Windows button on the computer stays glowing if i continue to hold the power button and if i undock it the led light is red. Also if i have it plugged it the windows button will flash 4 times and on the 4th time itll stay lit up until i release it I just got my computer back and  it's acting up again i would really appreciate a way to fix this

My computer will not shut completely off when I shut it down. The light for the wireless internet connect does not go black, it turns orange, saying that it is off but now the orange light does not come off unless I hold the power button down.  Also when my computer goes to sleep, when I press a key to turn it back on, it does not turn on. The screen stays black and the wireless internet connection light is orange. It does not boot back up anymore. 

A:HP wont shut off all the way and sleep mode wont let me turn...

Hi, Try the following. Open Settings and select System.  Select Power and sleep, then click on Additional power settings - in the following window, click on 'Choose what the power button does' in the left hand pane. In the subsequent window, first click on 'Change settings that are currently unavailable' ( near the top of the Window ) and then remove the checkmark from the box against 'Turn on fast start-up (recommended)'.  Click the Save Settings button, then close any open windows and restart the notebook. When windows has reloaded, download the IMEI driver directly from Intel on the following link, unzip the package and run the installer. https://downloadcenter.intel.com/download/26127/Intel-Management-Engine-Consumer-Driver-for-Intel-NU... When the installation has completed, restart the notebook. When the machine has reloaded, re-enable Fast Start-up and reboot the notebook once again - let Windows fully load for a few minutes before checking. Regards, DP-K

Hi, My laptop was not charge, I was not able to check the percentage of the battery & all of a sudden it shut down. I cant even remember if I shut it down or it shut down on its own, because I went to th rest room.. Few hours later I plugged it in the charger but t seems like it's not charging and then i tried to turn it on but its still not working. I need Help ASAP :-(  


It would help if you posted the product number or complete product name. You have only identified the notebook model series that it came from and that is not quite specific enough. Identify it and I will be able to give you instructions on performing a hard reset of your notebook. Is it still in warranty?Check your warranty status Here. Does the power\charge LED light up when a power adapter is connected to it?

Ad-Hoc requires that you restart the session each time.

Connectify pro has an auto start option that does this but it's a paid version, connectify lite is free but I'm not sure if has auto start.

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

A:Computer Doesn't Turn on, Fans and Some Lights Turn on Automatically

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

Computer was working fine at first. I installer a pcie card for wireless connection beside the slot for the graphics card. Then when i tried to turn my computer on again, there was no output on my monitor, my monitor couldnt detect anything at all from the desktop despite being connected to the correct port and being on the correct channel(hdmi). The desktop then beeps 5 times, pauses, then beeps 5 times again. This continues for a long time. The beeps are kinda long like each beep lasts like 2ish seconds. Please help me figure this out! Oh and no this didnt happen after installing pci drivers or anything,i didnt get to do it cuz this happened immediately after i installed the pcie card and tried to turn my computer on. Thank you

A:Pc wont turn on

Hi Sriram1501, and welcome to TSG. The 5 long beeps would usually indicate that the motherboard has failed at some portion of the Power On Self Test (POST). The exact meaning will depend on the exact brand and model number of the motherboard. If the computer is from a major computer manufacture it should also be possible to determine the meaning of the 5 long beeps based on the manufacturer and the full model number of the computer.

Im currently haveing a problem with my PC. The other day i went to turn it on and the computer would turn on but it wouldnt boot and there were no beeps. So because i didnt hear any beeps but the power turned on everything was running the hardrives the lights and and the moniter but no beeps and it wasnt booting i assumed it was a motherboard problem. Well not knowing enough about the motherboard to check anything the only thing i could think of doing was maybe resetting the CMOS or BIOS or whatever it resets by popping out the battery. So i pop out the battery put it back in and now nothing happens when i push the power button. The power supply still appears to be working as the little LED that tells me the Ethernet cable is plugged in is still on. I havent been able to locate the problem on the internet so i was hopeing for a little help thank you.

Hi and welcome to TS

I had that problem before, my solution was to remove the memory modules, and clean the slots on the motherboard using compressed air (they were full of dust), so you could try that.

I recently got a new computer, a shiny new hp pavilion a1630n, loaded with a Nvidia geforce 6165 LE graphics card. However, i was in the middle of playing a game when the computer shut off, tried to restart, and got as far as powering up and then making a really high pitched beep and then try to restart again, and then it would beep, and so on until i drained the power. Someone told me that this might be a graphics card issue, and it seemed to me like that would make sense since i was in the middle of playing UT2004 when it decided to die.

Does this problem have anything to do with my graphics card, or is it something completely different?

A:Gah!!! It Wont Turn On!!!

There is really no way to tell, and no way that you should be trying to find out, as being a "new computer" it should be under warranty.

I would be onto HP for a repair.

We are currently running 300 workstations, 190 of them use ONE model (Gateway E4620). There are some that had same problem (about 20). Initially it works great until a while later, it will not power on. I had to unplug the power cord and plug it back in then I will be able to power on. The staff have to do that every time.

What is the possible cause? What should I look for to get it FIXED?

A:PC wont turn on

I would start first by purchasing ONE new power supply with sufficient wattage, amperage, and if possible dual 12V rails. Replace one of the workstation's PSU and see if the problem remains. If the issue is fixed after a bit of trial and testing, order more PSUs for the remaining systems and replace them.

That's a start...next culprit if the PSU isn't the issue, is the mobo(s).

well i got a new WD 200 gig Hd for christmas, so I put it in as my slave to my 40 gig. First i forget to plug the cpu fan back in, but it was only on for about 2 seconds(big heat sink anyway). then i plugged it back in and walked off to tell that I had it on. when i got back it said (CPU UNRECOGNIZABLE) so i rebooted. It was stuck on detecting IDE drives... so I made sure to see if the ide cables were tight. then when i plugged my stuff back in the pc turned on for a split second, then it turned back off. Then i tried again and nothing happened. i looked in the case for inspection, but everything was Okay. I tried again and it turned on so that the fans made about one turn and the LEDs didnt even turn on. This is where im stuck.

Here are my specs:
Abit nf7-s v2 mobo

This was an 'ungood' occurrence!

This may have been sufficient to turn your chip into a "CPU UNRECOGNIZABLE"

Two Seconds with no fan at start up is a lot...hopefully the system was able to shut itself off in time as protection?

The symptoms you are now experiencing are indicative of an overheating problem OR a 'cooked' CPU.

The other day I bought some new bits to upgrade my PC with, installed new Mobo and cpu, fine, tried installing new GTX 295, but dont have enough qualifying molex connectors to run it at the mo (lost them) Powered up, worked fine reinstalled vista etc. I then tried to fit my GTX 295 again, with no luck so reinstaled the 8800 i have, tried to power, worked fine, then I smelt a burning smell, near the Dimm slots. Tried to power on again, nothing. My Mobo has LED's on it one red (power from PSU OK) and a green/blue one, to indicate that its running. Only the red light comes on. However if i wiggle tho 20 - 24 pin atx connecter, the blue / green led pulses, the fan spins a fraction and the PSU clicks with the pulses.

About 2 days ago, I figured id actually shut my computer down for once while I left for the weekend. So I come home last night, and it wont turn on. First thing I figure is that the power supply was tripped by a surge from the lightning storm the day before, so I unplug everything and Let it reset. (BTW, pc is running thru a surge protector, go figure). So I plug it all back in, its starts booting off, then suddenly shuts off after about 4 seconds. So, I take a few parts out, thinking I may have a faulty PCI card, and I turn it on, it boots fine and starts up. The computer is running for about 5 mins when I decide id like to sit the tower back upright, an as soon as it goes upright, it shuts off. Im not dropping it or putting it down hard either. I tried htis a few times, and 3 times in a row it shut off when put upright, and now it wont turn on again.

If I leave it off for a while, I will get the fans to turn and such for a split second, and the lights will turn on, but it all turns off imediatly. Yes, I have removed the cmos jumper and battery, and I am at a loss for what to do right now. You might need some sys specs, so here ya go:

P4 2.8 Intel Board (ill have to find out what make im not in the house right now)
450 WATT psu
750 Meg DDR ram

And I assume thats all you need to know.

Help me!

A:Pc wont turn on, need help

Replace the computers power supply and also replace the surge protector. Even after 1 surge, the protector could and probably will be toast

Processor- 2.4Ghz pentium4 HT.

Motherboard- 865GBF ( intel ).

GPU- ATI Radeon 256MB.

Ram- 2 x 512MB DDR 400MHz (hynix).

Hard Disk- 160GB seagate baracuda PATA.

SPMS-mercury 400W.

LAN and modem card seperate.

I used to use the system but after I recently bought another CPU, I stopped using it for 6 months. Now i need to use my old CPU again with the above mentioned config.

But when i start the system by powering it up, the fan runs, the led lights up, the hard disk rotates, the cd tray open and collapse but nothing else happens. not a single subject comes on the monitor not even the intial intel original motherboard logo that used to come earlier. The monitor remains completely inactive.

I checked my hard disk jumper, its in master. I also checked the bios jumper, its too in configure. I also tried to check with by removing the hard drive and just switching it on with a single ram stick of 512 but to no avail any success. I tried to switch on with only my motherboard graphics after removing the GPU card but the result remains unchanged. The fan runs, the SMPS fan runs, the motherboard LED lights up, the hard disk rotates but nothing on display of the monitor.

please help me and tell me were does the problem lies and how to correct it.

last september i built my own computer and it has worked until now. Recently my computer would not turn off even when i commanded it to, so i have had to turn it off manually. today it was working until i was playing a game, fear, and the game froze. i turned off the computer manually and proceeded to turn it back one, and it wouldnt. none of the fans would spin, none of the lights or leds worked, and my router does not indicate thecomputer as connecetd as it usually does when its off. lastly, when my computer was off but working, before this happened, one green indicator light would stay on in the computer, but now it is not. i believe the issue is either the mobo or psu, but i dont know for sure, nor do i know how to test it. please help, i would be grateful!!!!

A:please help pc wont turn on

well now its morning and mobo green led will turn on now. unfortunately the computer itself wont turn on, and the router still does not recognize the computer as being connected, please help me

Hi, well I turned my PC on and the blue light came on as usual. The fans started then they went off and so did the PC. So I turned it on again, but this time it didn't do anything. No lights came on and the fans didn't do anything.

I've tried switching the fuse, switching the plug socket, changing the wire, nothing fixes it. Something with the PC itself is broken.

It hasn't ever overheated, after all, it's a new PC - less than 1 month old.

I want to see if there are any solutions which I can try myself. Although I can't fiddle with the inside of the PC, it'll void my warranty.

If nobody can suggest anything I'll take it to a shop tomorrow.


A:PC wont even turn on

Typically this type of problem comes down to a hardware component and most often - power supply or motherboard.

It can, however, be any of the hardware components. If it's under warranty, you're best bet is to take it in and have them replace whatever it is. Don't trouble yourself with swapping parts, etc. It's not worth your time or money.

i have a Compac Presario S5100UK, its about 3 or 4 years old now i suppose,

the computer was switched on and i was listening to some music on media player while i was giving the place a tidy, but i accidentially knocked the wall socket switch off when i was hoovering and the whole thing powered down.

i left is powered down a good ten mins b4 turning the wall socket back on, but now the PC wont turn on at all.

on closer inspection there is a small green light on the front of the machine that is flashing on and off quite quickly, there is also a little green light on the back of the machine near to the power cable input socket and something inside is clicking as as the little light is fllashing.

i'v had a search on the sight and came accross this thread


which appears to be the same or similar problem tho under different circumstances, but there was no definate solution to the problem.

i tried leaving it unplugged over night and un/re-plugging all the leads in the machine, which is all i feel safe doing with my little knowledge of pc's, i presume it must be a power problem as its not switching on, but the flashing light makes me think that power is getting so far...?

so any tips or advice to help me get the machine going again would be greatly appreiciated

thanks for reading.

A:PC wont turn on.

If there is a switch on the back of the PC turn it off and then plug the main cable into the wall socket....then turn the switch on the back of the PC making sure all the cables are plugged in all the way....

If you get the same problem then it could be your PC power supply...which are inexpensive and easy to change.
