Windows 7: Crashing issue

My system is crashing randomly straight to the bios screen.

There is no BSOD or error message.

I can game for hours playing FFXiV or Borderlands with no issues then log out to watch a youtube video and end up staring at my bios screen in a split second.



It also happens when I am gaming. It can happen within 10 minutes of boot up or after 4 hours of gaming. Very random.

This is a new system (had it for about a month now) that I built.

There is nothing in my system health report.

I'm wondering if my power supply is faulty.

Windows 7 64 bit
Intel DP55WB Motherboard
Intel Core i7 875k proc
Intel BXXTS100H DHX-B LGA 1156 CPU Cooler - Copper Base, Aluminum Fins
OCZ OCZ3G1333LV4G Gold 4GB PC10666 DDR3 1333MHz
XFX Radeon 5850 1Gig Vid card
Ultra LSP650 650-Watt Power Supply

Thought I would run it by the experts before I go out and get a new PS.

Thanks in advance.

When you say straight to bios, do you mean a blue screen, or the computer reboots and you see the bios? If the power is just cutting out, it could be a bad psu. And since it can happen minutes or hours, I doubt it's overheating. If it's a blue screen, report back. Otherwise, I'd get the psu.

Thanks Lemur.. it's not a blue screen.

It is really strange.

I can be gaming and then literally in about two seconds I am staring at the bios launch screen and the PC reboots.

No error message at all. It just goes to bios super fast and reboots.

My theory so far is that the power supply just stops supplying enough power to run everything.. but no clue for sure.

I'm sure it is not a heat issue.

Never seen or heard of anything like this.

I will pick up a PSU tomorrow and see if that fixes the problem.

I appreciate the reply!

I've encountered the same problem since installing Final Fantasy XIV and am currently at a lost trying to figure out how to fix it. I've built my computer in March and did not have any problems with it, then I installed the Final Fantasy XIV beta last month and the computer started rebooting in the same way you are describing, except it never happened while playing the game. I can play the game for a couple of hours, then stop playing and maybe 30 minutes later it will reboot straight to the BIOS screen, with the only message in the event log being unexpected restart. It will also reboot if I don't play the game after a fresh power on.

This seems 100% random since I cannot reproduce it. I've run some stress tests and that doesn't seem to make it reboot, and it also seem to run fine in Safe mode. Tried disabling all start-up processes and non-windows services with MSConfig and it still crashes. When I initially got the problem with the beta, I formatted and the computer stopped rebooting and ran normally up to two days ago when I installed the Release version of the game.

I was wondering if changing your PSU fixed your problem, as I don't have any spare PSU around to test my system with.

It wasn't my power supply. I took it in to best buy and had them test it for me.

I formatted my drives and reinstalled and I was still getting the crash to the bios launch screen randomly.

I went out yesterday and bought new ram and I am no longer having the issue.

I don't plan on installing FFXIV again though, so I can't confirm for you if it was my old ram or the game which was causing my issue, sorry.

What video card are you using? a Radeon?

I'm using an XFX Radeon 5770.

I just finished formatting my PC and re-installing Windows 7. and it just did rebooted while doing some windows update. Which means FFXIV wasn't the problem after all, just a coincidence. I'll try running memtest for a while and see if anything comes up. I'm guessing this should be PSU or RAM related as well, just wished I had some spare parts around since there's no store I can go pick up the parts from locally.

Just toss up all your system specs if you don't mind, that way we can compare them and check for similarities.

Mine are in my first post except now instead of the OCZ ram I have 8 megs of Corsair ram.

The strange thing is my ram tested fine.. I just decided I was going to swap out parts till I replaced what was bad and my ram was the obvious first choice.

If you click on the small "My system specs" text on the bottom left corner of my reply, they should be there. Just in case, I'll include them in the post as well :

Just out of curiosity, when you tested your RAM, what program did you use and how many passes did you run?
