Upgrade/Troubleshooting mobo

I've been having some gremlins lately, and they're getting worse. I get hard reboots, generally of the kind where my monitors go blank, but the box keeps running for a few seconds - then the audio goes all screwy (sounds like a cd player locking up or something) for a moment, then CRASH! and hard reboot. At first I thought it was the CMOS battery because in the last week or so on post I've been getting intermittent CMOS errors of the "time to change battery" kind (clock resetting).

I'm so glad I just ordered a new CMOS battery (that's sarcasm ).

I would suspect virus/malware or some other software problem but I just did a clean install of XP SP3 about two weeks ago and I've had Kaspersky since then and I don't think that's it. But I'm open to argument there. Anyhoo, I've built my last 5 or so systems and this one feels like a hardware failure of the Mobo or RAM kind. From what I can gather there's no real way for a non-tech to test a mobo so now I guess I'm shopping for a new one. That's pretty much what I need advice on, an upgrade path.

My current system:

ASRock 4CoreDual-VSTA
(VIA PT880 Pro/Ultra/PT894 (Pro) + VT8237A
4xPCI, 1xAGP v3.5 , 1xPCI Express x16)

Intel Pentium Dual Core E2160 1800.0 MHz (socket 775)

2x Corsair VS1GB533D2 1024 MBytes DDR2-SDRAM UDIMM 266.7 MHz (PC4200)

RADEON X1650

4 HDD (3 IDE, 1 SATA)
1 DVD-RAM RW


I'd like to be able to use my current CPU and RAM in the new mobo, obviously, but I'd also like to upgrade to a more modern gaming setup somewhere between 2 and 6 months from now when I'm hopefully more flush. I'm broke at the moment so I want to spend the absolute minimum, but if I can find a happy medium between fixing my rig for minimum cash, and setting up for a decent upgrade later, that'd be great.

So I don't know jack about current hardware; can I get a mobo with two CPU slots, maybe? And then stick another in the second slot when I upgrade? Would that even be the thing to do (would it help me run modern games, or would some other way be more cost-efficient)? Or maybe a newer socket type that can run 775, plus something better coming down the pipe?

My philosophy is to stay at least one price point, generally more, away from cutting edge so don't take this gaming rig goal too literally. I'd just like to see some improvement, don't need to get crazy. It's not like my rig is bad now - plus I always play games about a year or more old, since I only have dialup and broadband is the only reason (for me at least) to worry about what's hot at the moment. Plus older games have been patched .

Thanks in advance for any help. Don't be afraid to ask for clarification, I rambled on and might've forgotten something obvious.

Okay, more info on my mobo troubles. Lately it's been refusing to post after I shut it down. I go in and wiggle things and then it will start. This morning I narrowed it down to the mobo power connector; when I wiggled that it started. Any advice on fixing that without replacing the board? I'm flat broke here and no money to replace mobo.

Well I'm broke so that's a pretty good clue I'm handy.

I'll give that a shot, thanks for the tip.
