Help

I've got a little problem with my pc.

Yesterday It froze twice, while playing a game. Twice on the windows desktop and once in the bios. Complete freeze, no keyboard response.
Then It didnt start at all. power on but black screen or garbled graphics. When I shutdown windows, the screen goes black but power remains on.
It did boot into bios this morning but it didnt detect my SSD drive. (which is my operation system)

Not overclocked. Did some tests on graphics/memory and cpu. All seemed ok. Temperatures 29C for mb and 38C for cpu. Some voltages seemed slightly higher than most people but only marginally.

I think it's my mainboard that's died or my powersupply but I dont know.
Most of my stuff is under a year old.

Any help much appreciated




I've got:

intel i7 860 2.8ghz
Asus P7P55D LE P55 Socket 1156
Asus 8800GT 512MB GDDR3
OCZ 4GB (2x2GB) DDR3 1333MHz/PC3-10666 Platinum Kit CL7 Unbuffered
OCZ 60GB Agility SSD 2.5" SATA-II
Sony AD-7200S 20X DVD±RW/DL/RAM Internal SATA
Western Digital WD5000AAKS 500GB SATAII 7200RPM 16MB Cache
Coolermaster RealPower 520W Modular PSU

I'll give that a go. But there is nothing different with my machine, nothing has changed over the last 8 months and it's been fine untill now.

I've updated the bios but no change.

I've found that one of my memory sticks is broken so that's at least one problem identified and removing it allows me to shut down from windows again without a problem.

Yesterday it still couldnt find my ocz ssd drive but this morning it did with no problem. running it now. The ssd drive was tested with another machine which was absolutely fine.

Could my power supply be faulty?

thanks

Looking at the config. A PSU of 550W is recommended.

Well, It appears one of my ram sticks was faulty. so now everything works again.
Why that stops my harddisc being detected i dont know.

Is the lack of power really a problem?

Well, I've got new ram that works. I've got a new 1000watts powersupply.
Again the same problem. Yesterday it worked ok. This morning I got a blue screen on startup that tells me windows (xp) has stopped. Can't go into safe mode either. Same message:

stop: 0x0000007e (0x0000005, 0x8054bfcb, 0xb84c3520, 0xb84c321c)

I have noticed that the system seems stable when I disable/disconnect either of my hardddrives.

The only thing I cant think of that i installed is Mafia 2 and I think that updated my directx drivers. But would that cause an intermittend problem?

Thanks for any help

At which stage exactly, you got this 0x0000007E error ? This is mostly related to a driver. Try removing all other third party device drivers and check. You can use msconfig also.

Thanks for the reply.

It happens just as it starts to load windows.
Computer starts up. goes through system check, bios screen. >pop< blue screen.

Same happens with safe mode.

If you have the installation disk, try a repair.

Some more developments.

I started with booting from my windows xp disc and i got the following blue screens in random order after a while when windows loads from cd.

pci.sys (no message apart from: stop: 0x000000be)

PFN_LIST_CORRUPT

IRQL_NOT LESS_OR_EQUAL


Sometimes, it even manages to boot into windows from the harddrive and then crash after loggin on.

I have found that if I unplug either of my harddrives and boot from either, the blue screens stop. And today, It booted up with no problem at all with 2 drives attached.

I'm starting to think my mainboard is broken. Anyone know how I can test it?

Oh and I just got another blue screen telling me:

BAD_POOL_HEADER

The pci.sys error I mentioned earlier tells me this:
pci.sys f73dbd24 base at f73db000, datestamp 41107d31
