New Computer sudden shut down problem

Hi there
This is my first post so sorry if it is not in the right place.
I have used Windows XP for about 8 years with absolutely no problems.
I decided to get a new computer with Windows 7 as the old XP was getting slow.
I ordered a computer from a BTO company.
The specs as follows

Windows 7 64bit Ultimate full version (DSP)
Intel (R) Core i5-3450 processor (3.1-3.5GHz / 4 cores / 4 threads / 6MB)
Intel (R) B75 Express Chipset
500GB Serial-ATA II
DDR3 1333 4GB x2 (8GB total) [Dual Channel]
24x Super Multi Drive
Intel HD Graphics (integrated graphics CPU)
Monitor : Flatron E2341

I had it for three days and then suddenly the system crashed like someone had pulled the plug. There was no BSOD.
It restarted but the same thing happened two or three times then it went to a situation where it would not even boot up.
I contacted the BTO company and they asked me to return it.
It came back with the information that they replaced the CPU.

I used it for a day but then the same thing happened but this time it restarts
and I can use for a while. The BIOS screen shows up and countdowns to restart.
This has happened about 4 times.

I am not a computer wiz but I know enough to check the event viewer which had a critical error Kernel-Power Event 41.
The computer experienced an unexpected shutdown or words to that effect.

I am not sure what steps to take next.
Should I contact the company again or is this something I have to sort out myself?
I am a little lost as I have used XP for a long time and I never experienced anything like this.
Thanks in advance for advice.

Bad CPU is very rarely seen especially on a PC... I think the problem is in the PSU - power supply unit. Power failures inside a computer is not something you should solve yourself if the computer is with guarantee. Also shutting down of a PC usually happens from overheating. You can use the free version of Everest to check your CPU/VGA-videocard temperatures. You can also use PC Wizard.

Welcome to Windows Seven Forums.

Please take a look at this Microsoft article: Description of Windows Kernel event ID 41 error in Windows 7 or in Windows Server 2008 R2: "The system has rebooted without cleanly shutting down first"

You've had the CPU replaced so what's happening now is probably related to the motherboard, RAM, or more likely, your power supply.

Personally, I'd take it back and ask for a repair, replacement or refund.

Thanks so much for the quick replies
I also was surprised to see that they had replaced the CPU. However, as it was working again I assumed that that was the answer.
I don't think heat is the problem as this situation happened once within 5 mins of boot up from cold and I actually had no programs running, just the O/S.

I think from what has been said I will contact them again and ask that they sort this out.
I don't want to start messing with things and maybe void the warranty.
Unfortunately this company says they do not do refunds!

I hope I don't have to come back to this forum for more advice!
Thanks again for writing back so promptly.

You don't say where you live, but not giving refunds for faulty goods is likely to be illegal.

I would avoid trading with such a company like the plague.

Yeah I think so too.
But this company was recommended to me by a couple of people who have had
no problems.
Let's hope they give me good service

I contacted them just now and they said send it back

I'll let you know what happens

Sending it back today

Thanks

OK, I hope they do the right thing for you.

I agree with the points above too, send it back get a new unit! You shoudl'nt ever mess with a electrical device if its under warrenty.

Well, I have finally got the computer back today
and so far no problems.
They said that they changed the RAM and also the power supply in case it
was part of the problem. They also ran a battery of tests to check the system
and ran the computer for 12 hours at a time but no shut down occurred.
So I can't really narrow it down to a specific problem but it seems that what they did
is working.
Hopefully will continue that way.
I have marked the problem as solved

OOOOOPS Too early........
I just posted this and then it happened...poof.......
Well ..what to do now?
Keep using for a couple of weeks and see what happens?
What the advice?
Thanks
