New machine, constant reboots
show user profile  Amish bob
I recently spent a small fortune on new computer parts.
New mb, i7 cpu, 12 gigs of ram, another 1gig 8800gts and three 24" monitors.
But the system is very unstable. It reboots all the time.
I don't think it's the ram, as i can leave the machine to render heavy scenes for 12 hours without problems.
But if i try watching a dvd, it might reboot 3-4 times.
The 3 monitor setup is alot buggier than i thought it would be, locking up if i rearrange the monitors etc. Is it normal to have problems with multimonitor setups?
I suspect that one of my hard drives is causing it, because the only way i can force a crash is to copy alot of files into a specific folder. Very strange.
Yesterday i was installing mirrors edge, when it froze. Since then i can no longer get into windows. Running repair from the cd now.
If anyone can give me some tips, I'd be very grateful.
Thank's

Remove as much hardware as possible, minimise the variables, isolate the problem.

Sorry to read about it. Your machine sounds great otherwise.

Try removing the hard drive and replacing it with another one.

Install Windows & enough software to test with on the second drive.

If that fixes the problem, it was either a software problem, or the drive.

If not, you've got a hardware problem, so as Nik says, you'll need to minimize the setup to isolate.

If the second drive setup works, wipe your new hard drive, re-install windows on the new drive, try again.

If it's still unstable on the new drive, but works on your second drive, the new drive is faulty.

Ensure you've installed latest drivers for everything.

i used to have this with one of my machines and it turned out to be the PSU. it wasnt giving out enough to the parts and when doing more you are using more power and it would reboot.maybe something to look at

I'll try stripping it down and changing the hd. Will take me all day.
I wish i knew some pc guru i could call, who loved this stuff. Instead of being the guy everyone else calls :p
is'nt there supposed to be a crash log generated?
There is nothing in the event viewer.

I hate how people assume that because you enjoy working with computers, you'll love trying to fix their old piece of junk. Like we all enjoy spending hours getting an old printer to work.

Anyway, I tried copying large amounts of data on a completely seperate drive, it still crashes.
So its' probably not that one hd after all.
The power supply is 700watt. I thougt that was enough. But I'll try to unplug one videocard, to see if that helps.

you could also try looking in the event viewer to see if anything jumps out there. control panel/admin tools/event viewer\system

nv4dsp.dll

?

Have you seen that listed, perhaps with a windows blue screen?

Or are you just getting random hard reboots and have never seen a blue screen so far?

bob, plug in one stick of ram, one graphics card, and one hard drive, then boot, and see if the problem persists. If it goes away, its going to be either your psu cant handle the load, or you have a bad stick of ram. If it continues its going to be a motherboard issue, sometimes theyre just unstable from the get go and need to be RMA'd. Which board is it specifically, I could help a bit more if I knew details (ram model number and manufacturer, board manufacturer and model).

sounds to me like your psu just cant keep up with 12gb of ram and both of those graphics cards if its rebooting during dvd viewing. Any i7 setup with 12gb of ram and more than 1 gpu should really be on no less than 1000watt psu, if for nothing else than to keep the psu in its optimum operating range.

What brand psu is it? A lot of psu companies mis-label their psu's to max burst load and not constant sustainable, so you might have a psu that can handle 700watts burst but can only handle 500watts constant load at max load, so when it tries to pull power its just dying out.

Yeah that sounds like a power supply problem.

I know you already said you don't think its a RAM problem, but my friend had this exact same issue (new computer, random restarts) and it turned out to be a faulty RAM chip.
