PC crashing on start up and when it finally turns on?

Question

Hi.
Recently, i've been having problems with my pc.

I built it myself - Phenom II 965, CM Hyper 212+ cooler, 4gb DDR3 HyperX RAM, Radeon 5770, MSI 870A-G54, OCZ Fatal1ty 750watt PSU.

I tried overclocking, put multiplier up so it was 4ghz - didnt change FSB speed or voltages etc. That ran unstable and blue screened, so took it down to 3.8, same result, 3.6, same result, so back to stock clocks at 3.4. Temperature was never an issue so i assumed then i had a dodgey cpu, but it ran fine at 3.4 so it didnt really bother about it.

However, recently, it has trouble starting up sometimes, and crashes on the MSI bios boot up page, so power off, same again etc, and eventually it works.

But, when it finally does turn on, it then crashes again. no mouse movement, or ctrl - alt - delete will work, so im forced to power off - holding it for 5 seconds, just pressing it wont work, then im faced with the same problems starting up.

Also, when it is on, gaming and prime 95 dont seem to influence it. As in, it happens all the time, even if it is just on the desktop with no open programs, so it isnt under stress.

What is wrong?
How can i fix it?
Do i have a dodgey part?
Could i get it under warranty if it needs replacing?

Thanks

Answer 1

If it crashes during MSI BIOS bootup then most likely this is a memory, motherboard or CPU fault, it won't be the hard drive. I would check the power supply connections though

You have quality power supply and is more than adequate so that is unlikely to be the fault



I would initially do a memory test using memtest.

http://www.memtest.org/

If the memory is clean then that would leave the CPU or motherboard and if they are under warranty then the supplier should replace the faulty part. The problem is identifying which is the faulty part and who pays to dismantle the machine test each part and replace.

I have been in exactly this situation and had to pay a fee to the supplier to test the machine even though they supplied all the parts. If you bought the bits from different suppliers then the situation will be more difficult.

Good Luck

you will need it

sounds like its overheating! i understand you're saying you have a fan blowing on it, yet while the heatsink isn't fixed acceptable with thermal grease, no quantity of air will keep it from overheating as there's no longer a stable touch patch for the warmth to pass to the heatsink. the undeniable fact that the pc is telling you that's overheating added confirms this. First is the CPU fan blowing down onto the CPU cooler, it maximum blow down, and not suck air up, no be counted if that's a side mount cooler, you like air shifting from the front to the back. If those are interior the nicely suited region, then i could get rid of the HSF from the CPU, sparkling the acceptable of the CPU and the backside of HSF with some denatured alcohol, until all the previous compound or pad is long gone as quickly as sparkling do no longer touch the surfaces including your epidermis, the oils will abate the cooling residences. Then word new thermal grease, like Artic Silver5 or ZeroTherm, in user-friendly terms a small quantity, bearing directly to the dimensions of a pea, and unfold it frivolously and as thinly as achievable with a razor blade, or mastercard. Reinstall the HSF onto the CPU, plug interior the fan wires. ability it on and attempt it out.
