Processor: P4 1.67 ghz; Motherboard: Intel P4 D85MVSE; video card: Geforce MX4000; 512kb memory; WinXP Home; Tower case
When computer is upright, will boot up, then lock up after about three minutes. When computer is on it side, boots up and runs fine for hours, even overnight. When I try to move it or tip it back up, computer locks up. I've uninstalled and reseated all cards and memory, checked and doublechecked all electrical connections. Use the screensaver to watch for when freeze up occurs. Even went so far as to have case open on it side while running and used bamboo chopstick to wiggle wires and parts and it ran fine. Moved case and it froze up.
Computer had a AGP video card, thought it might be video so removed card and replaced with above listed PCI video card. No difference.
well, he's asking for any ideas "out there" so I guess the other/other is appropriate It's just surprising that any ideas so far have not included ravaging his anal virginity by WingDing.

Not really since the new DX9 capable graphics cards came out from ATI and NVIDIA that has always been a persons choice for hardware and the New AMD 64's make getting a new CPU a no brainer..........So few now spend much time in the other sections accept for the hundreds weekly that keep installing their CPU's without thermal paste and come onto the CPU forum to ask what the burning smell is.
He proly figured he would get more help from the slummers down in the neither regions.
At least RichPLS is well grounded!! Well in an anime sort of way.
You can touch the real ones Well unless your name is Eno or you look like an Eno. Or basically any pasty skinned British chappy. WHAT? They kicked Hitler's arse.
First of all make sure theres nothing between the M/B and the mounting plate, like a loose screw or something, check your M/B mounting screws for tightness, if all that checks out OK, if you have one, or if a friend has one change out the P/S and test again.
Keep in mind the CDROM drives are really not designed to be run on their side, slot type CDROMS are, and Laptop type snapins are, but the tray type are not!, if you've successfully run a CDROM on its side, you've been lucky so far, if you haven't damaged it, I wouldn't push continuing that.
The MB is a Intel D850MVSE. I've replaced the power supply, still the same problem. In fact, it seems to be getting worse. I could not get the computer to boot up at all with the replacement power supply, Only once got the Intel Pentium splash screen, but after that couldn't even get the green power light to come on. I would get power to the fans and the CDRW/DVDRom light would flash, keyboard lights would flash, HD LED was red, but no green power light. Took out the replacement PS, put the old AGP video card and PS back in, set the tower upright and when I pushed the power button, CDRW/DVDrom flash, keyboard flashed, HD LED was red and I got a green power light, but no boot. Laid it on it side, it booted up to XP logon, logged on, and it froze up. Since then, I've been unable to get the green power light. If I get the power light it may boot; no light, no chance of boot. Someone told me the MD electrical bus sounds screwed up and I should replace the MD. Someone else told me they had this problem with bad RDRAM memory (board has RIMM). So, could it be memory?
I'm not yet convinced it is HD. But, is it possible to take the master drive and jumper it to a slave drive, put it on my system and check it? Or will having an active primary with XP OS on the slave drive mess up my own system?
If you take into account the weirdness of it performing better on its side, and you've made sure all the M/B mounting screws are tight, and in the right place with no overlooked mounting studs where they shouldn't be, and nothing metallic is loose, either on or under the M/B.
Then the only logical things left that could be affected by laying it on its side are either an improperly soldered in M/B connector possibly where the P/S connects[Highly unlikely], or a bad HDD, the RAM if it was bad is all solid state, so laying the computer on its side or standing it up should leave you with the exact same problem, however the HDD has moving parts inside it and could be affected by the movement of the computer, if the reading and writing heads are misaligned, so under those circumstances, with the information you've given, I'd say the HDD could be the problem.
There are literally no other parts in a computer that could be affected by laying it on its side, as long as the CPU's heatsink/fan is securely fastened in place, along with all the PCI cards in the machine, but CDROM drives but that doesn't have a thing to do with initial booting.
I have to ask you was the P/S properly rated for the computer hardware, and you knew for a fact the P/S was good?, if the answer to that question is yes then you've eliminated the P/S as the possible problem. So I would move the HDD to the top of the list as being the problem.
CPU heatsink on right? clips or whatever it uses not bent or stretched?
I was thinking that standing upright the heatsink is pulled away from the cpu.
On its side the weight rests on the cpu.

It was a grounding issue. I took everything out of the case. Put it together on a sheet of cardboard and started it up, booted just fine. Wiggled and tipped the MB and there were no problems, ran chkdsk, too, all was well. Put everything back in the case, no power. Took the MB out, put electrical tape on the back of each mounting hole. Took the four extra metal standoffs out of the case. Put it back together with fiber washers and...it booted!!! It is running just fine as I type this and it's been about 1/2 hour, wiggled the case just for good measure and it's still working. Thank you everyone for the input. Just so you know, this was the first time I've ever taken a computer all apart and put it back together.
P.S. RichPLS, have we met before? The picture is a pretty good likeness
congrats on the fix action. good to hear it is working for ya.

Uhh, yes, PM me for a time...BTW, I am glad you got your computer working and the shorting caused no long term damage.
