Last night, I took my PC downstairs to give it an overdue cleaning (had been about 6 months since last clean). I used some compressed air to clean out the CPU fan, the PSU, two ventilation fans, and gave the case interior a once over as well. I did not disconnect anything on the inside.
I then took the PC back up to the office, reconnected all of the appropriate external wiring and booted up. I got as far as the desktop, then the computer froze. I rebooted the computer and this time, after getting to the desktop, the screen went black except for about 8 thick white diagonal lines across the monitor.
I tried reseating the video card and booted a couple of times with the same results.
This morning, for a lark, I tried booting again.
The first time, I encountered a Post Code beep that was not discernible at first because there was a lot of little beeps all over the place, but then I believe I heard a long beep and a short beep repeating. I'm not 100% on this since it didn't happen again the second time. I looked at the code on the motherboard and while windows was crashing it displayed the code FF, which my mobo manual says is just a boot attempt.
The next time I booted, it booted to desktop and then the screen went black (with no diagonal white lines).
Given that I have only attempted to clean the dust out of my computer, can anyone tell me the most like problem?
My system specs are as follows:
Mobo: Abit AV8 3rd Eye (about 2 years old)
Processor: AMD Athlon 3200+ XP with factory supplied heatsink and fan; arctic silver compound used on initial installation about two years ago. Fan/heatsink and processor has not been removed since initial install.
Memory: 2 x 1GB Apacer PC 3200 DDR 400 (brand new)
Video: EVGA 7600 GT Superclocked (512mb; brand new)
Audio: Soundblaster Audigy (about a year old)
PSU: ATX 450watt (approx 2 years old)
HD1: 80 GB ATA (Master with windows)
HD2: 500 GB SATA (slave; has dual fan cooler attached).
Any help would be greatly appreciated.
