Hello, everybody. I've got quite a problem that I can't seem to solve.
Recently, I've upgraded my eMachines T6412 from an Athlon 64 3700+ (and a 350W PSU) to an X2 3800+ (and later a 430W PSU). Windows detected the dual core on its own and made the necessary changes. I didn't have many issues with my computer before this, but ever since I've installed the dual core processor, I've experienced several freezes, reboots and at one point some BSODs. After upgrading my PSU, I haven't had any BSODs, but the computer still reboots. The processor was reported to be working fine when I bought it. My specs:
OS: Windows XP Home SP3
Processor: AMD Athlon 64 X2 3800+
Video: MSI ATI Radeon HD 4670 512MB PCI-E
RAM: 2 GB PC3200 DDR
Sound: Turtle Beach Riviera
HDD: 200 GB HDD (with 80 GB HDD as a slave)
PSU: Antec 430W PSU
Motherboard: MSI MS-7184 (ATI RS480 SB400)
Playing a modern computer game (something like Team Fortress 2 or NBA 2K10) causes it to freeze or reboot. I can navigate through the game menus, but when I try to load a map (or start a match), it reboots. When I tried MLB2K10, it actually loaded the gameplay and ran beautifully with the power of dual core... for three minutes. Then it crashed returned to the desktop instead. Unreal Tournament 2007 made the computer reboot before the game even started.
Sometimes it doesn't have to be a game to deliver a reboot knockout. For one reboot, I merely scrubbed through an online video (albeit a high quality one) in Mozilla Firefox. Merely clicking a link in Firefox made it freeze as well, but this happened after MLB2K10 crashed to the desktop.
I've noticed that when Windows XP loads after BIOS, the loading bar takes much longer than usual. It's the same way with the Welcome screen and loading the desktop - takes a while. I tried running Chkdsk to remedy this. It seemed to improve the speed, but after I restarted, it went back to its slow ways. I ran ComboFix to eliminate any possible viruses, defragged my hard drives, ran a registry cleaner and did another virus check with AVG.
I've already ran memtest for 5 passes overnight, and there were no problems with the RAM. I've already installed the latest ATI processor driver. I also installed ATI's Dual Core Optimizer, but then uninstalled it since I thought that was causing my processor troubles. I did a Google search and saw that it caused BSODs, so I haven't reinstalled it - and I haven't had BSODs since.
I'm not sure if this is a video card issue. I have the latest ATI Catalyst 10.4 drivers, and I am able to play old games like Quake 3 with no problem. On the other hand... when I play a modern game (or do something CPU intensive), the program will crash, or the system reboots/freezes. Sometimes the game will actually play for a few minutes before the crash happens.
Temperature doesn't appear to be an issue. I bought a better case fan and a processor cooler to replace the stock eMachine fans. The processor runs at around 45 C at the BIOS, but I'm not sure how hot it runs under intense loads. The video card runs at 43 C idle, and the fan is set to 100%.
I've run out of ideas as to what the issue can be. It can only be one of the hard drives, the Riviera sound card, my motherboard (which has one blown capacitor, but still runs fine with the single core) or perhaps my copy of Windows XP is done for.
Any help or suggestions would be appreciated. Thanks a lot for reading.
