[ksrokiller]

Hi,It started while browsing web suddenly the screen blackout tried to turn on there is no power and light went to rma the power supply upon reinstalled back tried to boot it is stuck on the infinite boot loop no display.

Tried resit ram, reinstall cmos battery,take out graphic card to boot only with intergrated graphics, reinstall the connecters(sata cable, front panel cables), anyone experience this before manage to solve it? Thanks!

move your ram from slot 3 & 4 to slot 1 & 2
oh and go into BIOS "Load Optimized Defaults" if needed... GL

can reinstall windows?

 

[ksrokiller]

can reinstall windows?

No i can't,It does not boot into bios, there is nothing on the screen

usually your symptoms tell me its a mobo issue... just get a refurbished mobo.

 

[namex123]

did you test without the ram stick.
start power still the same cpu fan spinning?

 

[undead102]

Could be psu or mobo. Try swap to different working psu or mobo to test.

Yes have tried this also the same cpu fan spinning

I send back psu to corbel again they have check and it was able to boot on their side so psu no issue.i don't have spare mobo to test unfortunately

Thanks will look to into this if not resolved.

Then it could be the mobo. Try a different mobo? Have this issue before and after swapping a new mobo the problem was solve.

Ok will look into this thanks!

I have encountered similar problems quite a number of times in the past.

It was either the RAM or motherboard issues.

(Most of the time, people erroneously think it is due to the PSU when their PCs can't even start booting. Usually, it is not due to PSU).

Quite a few times, it was due to RAMs. Taking them out, cleaning and putting them back solved the problem. RAM seldom spoils.

About 4 times in the past 10 years, it was motherboard malfunction (as recent as just 2 months ago and I have 3 PCs now) and I could only confirm it after testing every other components (including the CPU since I have 2 PCs with CPU using the same socket type) and I deduced that the only possibility was a faulty motherboard. So I bought an old working motherboard to replace it and the PC worked fine again.

Test with just Power supply, Motherboard + CPU + RAM, with onboard/integrated graphics.

No any other peripheral devices.

If it still cannot boot into BIOS, then most likely motherboard or RAM. Although possible, it is rarely the fault of CPU or PSU. Much more likely is motherboard fault than the RAM because motherboards have a much shorter lifespan than RAM.

ps. You can check shopee or aliexpress if you intend to get a motherboard cheap.

Yes have tried this also the same cpu fan spinning

maybe your bios mess up try manual.
CLR BIOS 2 pin. Look video easy to understand how to do 4:10

You also can use tester screwdriver.

Hi,

Thanks for your advice and sharing your experience!

For mine case when the issue started the psu was indeed spoilt send to rma and service centre tech have tested and replaced as still under warranty.

But now i guess it would be the motherboard.

TS had tried reinstalling the CMOS battery.

So that should have cleared the CMOS and reset it back to default already.

Frankly, it is impossible to confirm unless you have spare working components to test.

1) Set up with just PSU, CPU, motherboard running with integrated graphics. No RAM or any other devices or cables installed.

When turned on, motherboard should give beeps sound to inform no RAM. If no beep, then possible motherboard faulty.

Even if there are beeps, we still cannot confirm that the motherboard is ok.

This is because the motherboard may be faulty in some other aspects.

2) Set up with just PSU, CPU, RAM (just 1 stick), motherboard running with integrated graphics. No any other devices or cables installed.

If it cannot POST, then most probably RAM or motherboard.

The beeps if any will give clue.

You then need to have spare RAM or motherboard to confirm which one is faulty.

(ps. In the above, I am assuming the CPU is ok. I have 2 old PCs with LGA775 DDR2 and 1 new PC with LGA1151 DDR4. The 2 old PCs are 10 years old (or more, I can't remember specifically). I have always built my own PCs since year 2001 and their CPUs never fail despite heavy use but motherboards spoiled and replaced. DO NOT rush to get a replacement motherboard unless you are sure that your PSU, CPU and RAM are all working fine.

 

[Nelia8686]

Yeah have build several PCs in the past. Since pentium 4 days until now. Never had a CPU die before. All the CPU is working 100%. The parts that always die and have to be replace is always the motherboard, sometimes the psu and very very seldom the ram stick. If you don't have spare parts to test is very hard to troubleshoot yourself if it is a hardware fault. If software fault is easy to fix.

Thanks! I just tried this with a flat head screw driver, did not resolved it too
