I've built all my systems with these exceptions: My laptops The first system I had, which was built by an electrical engineer in the early 1990s, I bought it used from him. Spec on this system: GIGABYTE GA-EP45-UD3R LGA 775 Intel P45 ATX Intel Motherboard Q8200 (2.33Ghz 45nm Core2Quad), copper core stock heatsink/fan PNY 9600 GSO dual DVI PCI-e GPU 2x2GB GSkill blue DDR2-667 RAM EVGA SuperNOVA 550 G2 550W 80 Plus Gold Modular Power Supply MIT MyHD-120 HDTV PCI + daughterboard Hercules Game Theater XP (GTXP) PCI sound card + breakout box 120GB IDE HDD for OS/Apps Western Digital 2TB Red 5400 SATA III HDD for secondary storage Midtower case 2x 120mm fans Since I picked up the mobo and video card from an AT member it seemed to be working fine, at Xmas 2016. Fine except for the fact that it never once recovered from any S3 Suspend. Searching online reveals that this is a common issue with this motherboard. My workaround is to do a wake from shutdown on a daily basis and set the time it wakes up, if I want it on within the next 24 hours.That at least, gets the system booted at the time I need it on to make my programmed HDTV recordings. Well, the system has gone strange for the last couple months or so. Sometimes it seems alright. But it goes bonkers... when or why, I haven't a clue. The most stark symptom is seen when the system starts. Instead of the typical booting video I usually see, there are strange colors (not the usual black and white). I think there's a pervasive green all over the screen (I'm green blind, so that's a guess!), but then there are crazy figures all over as the machine continues into the boot sequence and Windows never loads correctly. Other times, the system will just lock up in Windows. I can overcome this syndrome by booting into Safe Mode (press F8 during boot). Once in Safe Mode, I reboot and it's OK. Well, almost all the time, because yesterday, that didn't fix it and I had to do it again. It's running Windows XP. I've been meaning to try Win7, even a trial, but haven't gotten around to that. I installed a fresh copy of XP in the 3rd boot partition a couple of months ago or so and everything seemed dandy for a while, but then the problems resurfaced, WTF. I ran Memtest on the two 2GB sticks yesterday and it had zero errors after 2 passes. Any ideas what might be wrong? The power supply is pretty top notch and not old. Should I look for another mobo/video card on ebay? Replace the video card? I figure a mobo replacement is probably a good idea so I can have S3. I need that to support the system's main function which is to timeshift HDTV programming. Crucial in a replacement mobo is PCI support... the HDTV card needs that and if I am going to continue to use the sound card, another PCI is necessary. Plus, there needs to be space for the HDTV card's daughterboard, which nestles up against the PCI HDTV card.
