Lockups/Restarts when doing processor-intensive work

pratt121pratt121 Registered User new member
I have an AMD 64 3000+ running on an nForce2 chipset with 2GB DDR. Pretty basic system I've been using since my last one died and I haven't bothered to upgrade since I have a 360 I'm pretty happy with. No overclocking or anything whatsoever. I have an Antec case with two large fans (in front and back) and a side vent fan blowing directly on the sizable processor fan/heatsink. The case gets plenty of airflow.

The problem is:
-Every time I load up a game, even a really old one like KOTOR or Dark Age of Camelot, the system either locks up (and doesn't respond to keyboard input or anything but a cold restart) or restarts randomly.

-The same problem occurs when I try to fullscreen video, either from DVD, harddrive, or Hulu. Seems to work when it's not fullscreen... weird huh?

-While it didn't happen at first I've begun to experience lockups when using PhotoShop, which is kinda the last straw. I need to get something done about this quickly or I'm out of a job with a pissed off client.

-When it locks up, the PC makes a high-pitched damn-near ultrasonic sound... Can't figure out where it's coming from though.

This is my third (and probably last) AMD processor. I've had similiar issues with past processors failing due to overheating, with similar symptoms. Is this the likely culprit? Are there tests I can use to determine this? I'm not into paying someone to tell me I need to get a processor/motherboard (in this case I'd just buy a whole new system and salvage what I can from this)

    Random lockups under load are usually either heat or power related. If you think it's cool enough, I'd start looking at your power supply. High pitch squeal is another giveaway on a power related issue. How big is it? How old is it? Cheap PS's can go bad after awhile and may have never had the muscle to live up to their alleged rating. Unless you're buying top-shelf, replacing one could be a relatively inexpensive fix.

    I learned all this last month the hard way when trying to upgrade my video card and CPU. YMMV

    Did some tests with powersupplies ranging from 400W to 700W and didn't get any better outcomes.

    So I just ordered a new PC:
    -Intel Core i7 860 (2.8GHz)
    -6GB of RAM (3x 2GB) DDR3 1600
    -GeForce GTS250 1GB (figure I can get a better one later, can't afford to go all the way just yet)
    -1.5TB HDD

    And, under the guise of borrowing his PSU to test my busted PC, I hijacked the Blu-Ray drive from my dad's computer and replaced it with a DVD drive. Let's see if he notices, he doesn't have any Blu-Rays, and I doubt he even knew there was a drive in there... So, you could say I "liberated" it.
