|It very well could be the graphics card if you think the timing of the installation of the video card coincides with the freezing. |
Generally speaking, when systems freeze, I think of three things:
1. Diagnostics, 2. Diagnostics, 3. Diagnostics
There's no way to tell what's going on w/o making sure all your system settings are correct in BIOS and OS, correct & updated drivers installed, as well as making sure your system is clean of malware etc. If those are all OK, I'd test everything:
- HDDs: Test with your Hard Disk Drive with the manufacturers HDD diagnostics tools: Seagate\Maxtor: Seatools. Western Digital: DataLifeGuard. Hitachi: HDFT (Hitachi Drive Fitness Test). Samsung: HUTIL. Fujitsu: FJDT (Fujitsu Drive Test) NOTE: Toshiba took over Fujitsu's HDD business; Toshiba (not sure if Toshiba has their own HDD diagnostics utility). NOTE: Some PCs have On-board Diagnostics as well (run the test in the BIOS).
- Optical ROMS
- RAM. Test with your PC Mfgrs Diagnostics, if provided like PC Doctor (IBM, HP), Dell Diagnostics. MEMTEST: http://www.memtest.org/, Windows Memory Diagnostic: http://oca.microsoft.com/en/windiag...
- Power Supply: http://pcsupport.about.com/od/tools...
- Make sure motherboard is correctly mounted in the case.
- Check motherboard for any bulging or leaking capacitors, http://jonrosensystems.com/computer...
- Make sure the RAM modules and Add-In cards are fully seated in their slots, and that the slots themselves look clean and undamaged.
- Look for loose or cracked data & power connection cables (I once found a loose power wire in a MOLEX connector on a flaky system).
- Look for loose, dry (ungreased) CPU/Heatsink.
- Look for noisy or hard to turn fans which indicate bad bearings.
- Is the system clear of ALL dust & debris?
- Does it Freeze in Safe Mode? A system that freezes in Safe Mode is fairly rare.
- If hardware seems ok, are there any firmware updates for HDDs, Optical drives, Video cards etc.
The last PC that I saw freeze , and by freeze I mean it freezes while in the OS, was a P4 single Core CPU, XP system w/ an Intel board. The whole CPU/heatsink/fan assembly was a tad loose from the motherboard and wasn't even fully seated down into the CPU Heat sink snap downs on the motherboard. I'm assuming it was the ahem, "technician" who looked at the system prior to me. That "technician" also installed the main case fan backwards.
Never ASSUME anything.
MOOOOooove! OH and you're welcome!
