windows 7 x64 switches on/off before any screen appears

April 8, 2019 at 03:28:18
Specs: Windows 8, 2x4
Hi,
so 1 day W7 did not start, it starts a few seconds then stops, then continues like that.I took it to my local PC store, they said the RAM needed reseating. iT WORKED but later started the same syndrome, unable to staRT UP.
i'VE TRIED, changing RAM seats, using just 1 stick, replugging all parts inside whole PC. Just between startups sometimes, about 1 in 30 it boots as it should, rest of time not at all or with a few seconds on off?
W7 64bit O/S checked and OK
the Mobo: ASRock Z77 Extreme4-M Motherboard Intel Micro ATX Socket 1155
checked and OK
Memory: Corsair - XMS3 4G - RAM - DDR3 SO 1333 x 2 checked in Windows OK but cant use Memtest 86 the interface is different to on website, also unable to boot from Flash drive.
CPU: Processor - Intel Core i7 2600K / 3,4 GHz - LGA1155 Socket - L3 8 Mo
H/D hgst 1tb checked and OK
Wireless: TP-Link - TL-WN851N - Carte WiFi N PCI - 300Mbps - MiMo
Power Supply: Be Quiet - BQT L7-530W - ATX - 530 W appears OK
DVD R/Writer x 2
Internal multi card reader

ANY SUGGESTIONS WOULD BE WELCOMED

RAM issue:
Remove memory, clean contacts with a soft clean pencil eraser both sides, remove dust, then pop them in ans out of slots 4 or 5 times each to burnish contacts in sockets. Try booting again.

Memtest86 can also be run off a bootable CD that you can burn using another computer.

Test:
Can you boot into BIOS Set up? Will it stay on for a while?

What test did you make to ensure power supply is good? This behavior is consistent with with a power supply that is going bad or is gone. The best test if it does not boot into BIOS set up is to swap the power supply out with a known good one either from a working machine or one purchased with the understanding that it could be returned if it is not the problem.
Another way is to Google testing computer power supply with a digital voltmeter and following the instructions.

Test:
With the power off, open the case and carefully wiggle the CPU heat sink. If it moves at all then the heat sink needs to be removed, all old thermal compound needs to be removed and replaced with new (properly) and the heat sink reset and locked down.

You have to be a little bit crazy to keep you from going insane.

try a different power supply, you can ask a shop or a friend of yours.(anything 350Watt or more is good)

if it doesnt boot with a new PSU (powersupply), try re-seating the CPU-heatsink AND re-apply thermalpaste (should only cost about 3$)

"about 1 in 30 it boots as it should, rest of time not at all or with a few seconds on off?"

This could mean the motherboard is just re-training the memory (trying different memory timings for default JEDEC frequency's, JEDEC are certified stable)
Re-training can cause the machine to reboot multiple times, but it should only do this 1~5 times.
The above should only happen once, since after a successful the working memory timings will be saved in the bios.

if you do get into windows, do a full shutdown and manually reboot, then to test RAM, try this free software:
https://hcidesign.com/memtest/

allow it to run till 100% at least, but do not give it more ram than you have available :D

AMAZING REPLIES SO QUICKLY ........ thanks
sO IN REPLY
It's just booted correctly 3 times!
Now to try https://hcidesign.com/memtest/
a lot easire than MEMtest86 which I couldn't get on with at all after hours of trying.
NOW SOME OTHER ANSWERS FROM ME
When I took it into my PC shop they said the grease was replaced, 'processor' and the fan just incase a problem although I never had a problem with it.
I tried Windows Memory Test several times & although it showed no problems during it's use I got no readout after reboot as it said?
''Remove memory, clean contacts with a soft clean pencil eraser both sides, remove dust, then pop them in ans out of slots 4 or 5 times each to burnish contacts in sockets. Try booting again.

Memtest86 can also be run off a bootable CD that you can burn using another computer.

Test:
Can you boot into BIOS Set up? Will it stay on for a while?''
I did remove RAM and clean with a good rubber but only reinserted onnce!
I have given up with memtest86 as it has no professionaly written help that I can reach. My instructions look nothing like available on the net?
I can boot at present for how long I don't know so I can get into bios!
I was told by local company Power Supply OK

You should be testing with either memtest86 or memtest86+. Download, create a bootable disc, boot off it & let it run. One full test series will give you a general idea if there are any problems. If it comes up clean, it's still advisable to let it run for a while just be be sure. Once started, it will run continuously until you manually stop it.
NOTE: you may have to change the boot order in the BIOS.

You can also try booting off a Linux disc. It comes with memtest86 included & you can also try running the Linux OS for a while to see if it's stable or not. If it is, you might have a problem with your HDD or Windows installation. To test the HDD, try CrystalDiskInfo.

Linux Mint is very similar to Windows. You wouldn't be installing it, you would be running it directly from the DVD. No changes would be made to your HDD.

Memtest86 & Memtest86+ are very simple to use. There should be no reason to ask for tech support. I'll make it easy for you - here's a direct download to the ISO file. Unzip it & read the instructions. If you need software to burn the ISO image file to a disc, try CDBurnerXP.

RE #5, that's why i recommended memtest by hci design, had mediocre experience with memtest86.

Here is an example of Buildzoid over at AHOC trying to stabilize a ram module:
https://www.youtube.com/watch?v=mhp...
He does however push his RAM to the limit, but hey so do i.

recommended is to let it run up to 1000%

Could be a bad switch. If you feel comfortable running your PC with the case open and poking around with a screwdriver when the thing's plugged in, you could disconnect the power and reset switches, then try to turn on the PC by tapping the power switch pins with a metal screwdriver.

Could be bad power, especially if the PC shop is competent enough to actually clear the PC of malfunction. Try a UPS sized for your PC.

It's rare that an ATX power switch goes bad. It's just a push button similar to a doorbell button. It's not like the mechanical switches used in the old days of AT.

It could be the power supply. I'm not a fan of "Be Quiet" PSUs although they seem to get OK reviews. Most reviews seem to be German? https://tinyurl.com/y2s4fpgn
