Hi all,
Summary:
Am having a custom-built PC that worked just great for the last 6 months. Then I started getting random issues (BSODs, mouse-keyboard freeze, computer fails to shut-dowm after OS shutting down). For the past two weeks now, the issues are getting more and more frequent. No significant changes were made to the hardware or software. Have run UltimateBootCD scans, removed almost all hardware except bare bones CPU, Mobo, nVidia graphcis card, memory, PS/2 keyboard and mouse, and power supply, plus fresh install of Vista SP1 32 bit/WinXP Pro with/without any third-party drivers. Once a freeze happens, it is a lot faster to happen again even after a fresh reboot. Freeze happens with bootable CD programs also = (that;s why I did not list HDD and DVD drive into the bare bones list above -- if I have one of the two, I can start the system, and issues happen).
Here's the current configuration (see more freezes here than BSODs):
Intel Core2 Quad Q6600 2.4 GHz
Abit Fatal1ty FP-IN9 motherboard. No overclocking.
2 GB RAM (passes UltimateBootCD tests)
EVGA 8500 GT PCI-x graphics card
Antec EarthWatts 650W power supply
Plain old PS/2 keyboard and mouse. USB mouse also has same results.
Vista SP1 32-bit (with and without latest updates). Also tested WinXP SP2 Pro, same issues. Also bootable CDs result in the same issues.
Prior, original configuration (more BSODs than freezes)
4 GB RAM (passes UltimateBootCD tests, Windows Mem diags tests)
Two SATA 3GB/s 500GB Seagate hard-drives (pass all scans Windows, BootCD)
One SATA Samsung DVD-RW
One Sony PATA DVD-RW
Curiously, if I enable boot-up memory tests in Bios, it fails for 4GB and keeps on rebooting. Yet, with bios RAM tests disabled, Windows Mem diags and UltimateBootCDs all pass 100% after 7-10 hours running)
Installed SpeedFan on otherwise fresh OS install. Let it track and show temperature and voltage charts all the way till freeze happens. There is no jump seen in either temperatures or voltages. This is NOT tracking nVidia card temperature though, which does get hot, but not enough to prevent me from touching for several seconds.)
Some folks suggest Power supply may be bad. Also nVidia cards have over-heating issue (per the news all over the place a few months back). Abit (motherboard company) seems to be gone!
Everything (except keyboard, mouse, and Sony DVD-RW, is new and under warranty. Just that I do not know "what" is bad.)
Bought Asus P5Q SE mobo to see if that helps. But a google search before opening the box said that folks have similar problems with that Mobo too!
Please help...
