Unstable Software Beahviour - Install Crashes - Windows 7 32Bit
Hi All.
The last month I have observed some very peculiar software behavior on Windows 7. I don' do overclocking at all.
Symptoms: Basic programs and Drivers fail upon install and after some programs do install, fail to run after reboot. Programs don't register correctly for uninstall.
What I have Done: Reinstalled OS7 Ultimate on fresh HDD. I have conducted a thorough CPU, RAM (Memtest86) CPU and PSU test with Raid64 - All check out.
Conducted Malware and Virus tests with 3 different Programs, Avira, Mcafee and AVG - No conspicuous treats found - tagged EXE. from Cracked software - Sorry.
I have tried fresh install of OS7 on 2x different HDD's and problem remains - I cannot even get my MOBO drivers to install - Chipset Driver fails on run, ATI Graphics Catalyst Control does a partial install but fails before complete. Audio Driver refuses and crashes halfway trough install. Network driver is only driver that installs.
Tested all HDD's for issues with Paragon Partition Manager and drives check out fine. Will conduct another test with Crystal Disk Info 6.
Programs like VLC, Media Player, WINRAR become severly corrupt and fail after reboot - in some instances they refuse to run at all upon install. Worth noting that these programs are not displayed when Trying to uninstall them - Windows does not even register them.
I have had the MOBO, CPU and Ram tested at supplier - No faults found, apparently. BIOS was updated. However they did not test programs like VLC, Winrar etc. - so I cannot fully trust their consensus. PC Was tested with their own HDD and most things work....
STILL GOING TO DO:
1. Obtain a spare HDD, do complete and thorough format on drive, Download fresh drivers from applicable vendors and try again from fresh OS7 Install.
2. Use new SATA connectors on drives to illuminate potential fault.
3. Will only run Operating HDD, no spare drives whatsoever.
This sums up what I have tried and still at a lost. From testing it is safe to say that the MOBO, CPU and Ram are fine, so I need to illuminate the variables which the 3 the above test will determine.
QUESTION:
Could a virus be at fault here? I have also noted that certain programs become corrupted when transferring from USB to HDD, after downloading them fresh.
At this point in time I'll be focusing on the HDD as this could also be blamed for corrupt files.
Any further suggestions will be greatly appreciated.
